feat: responsive pause/stop, non-blocking update with progress bar, delete saved sessions (1.5.0)

- carve: check cancellation inside chunks and per hit; reassembly stage is cancellable
- status exposes `stopping`; UI shows "Pausing…" immediately
- Tauri update commands run off the UI thread; download percentage reported
- delete autosaved sessions manually (one/all) and by retention setting
- chore(release): 1.5.0

+## [1.5.0] - 2026-11-03
+
+### Added
+- **Update progress bar.** The in-app update shows a real download percentage bar followed by the verify/install/restart phases.
+- **Delete saved sessions.** Each autosaved session in the sidebar has a delete button, plus a "delete all" button. Settings gained "Delete autosaved sessions after" (never, 7, 30 or 90 days), applied on startup. Sessions open in the app are never removed automatically.
+
+### Fixed
+- **Updating no longer freezes the app.** The update check and install ran on the UI thread; they now run in the background.
+- **Pause and Stop respond right away.** The signature scan only checked for the request once per 8 MiB block; it now checks continuously, and the UI shows "Pausing…" immediately.
+
+## [1.4.0] - 2026-11-03
+
+### Added
+- **Browse by folder.** A Folders view next to grid and list shows what was found one folder at a time, like a file manager: subfolders first with their file count and size, then the files, under a clickable breadcrumb. The sidebar folder tree navigates in this view, and filters still apply.
+- **Recover whole folders or parts of them.** Folders and files are ticked with tri-state boxes that persist while navigating; a ticked folder takes everything inside it, and unticked subfolders or files stay out. Each ticked folder is recreated in the destination from itself down (`Documents/Clients/Project` → `Project/...`), with the usual hash manifest.

+## [1.5.0] - 2026-11-03
+
+### Adicionado
+- **Barra de progresso da atualização.** A atualização dentro do app mostra uma barra com a porcentagem real do download, seguida das fases de verificação, instalação e reinício.
+- **Apagar sessões salvas.** Cada sessão salva sozinha na lateral tem um botão de apagar, além de um botão "apagar todas". As configurações ganharam "Apagar sessões salvas sozinhas após" (nunca, 7, 30 ou 90 dias), aplicado ao abrir. Sessões abertas no app nunca são removidas automaticamente.
+
+### Corrigido
+- **Atualizar não trava mais o app.** A verificação e a instalação rodavam na thread da interface; agora rodam em segundo plano.
+- **Pausar e Parar respondem na hora.** A varredura por assinatura só checava o pedido a cada bloco de 8 MiB; agora checa continuamente, e a interface mostra "Pausando…" imediatamente.
+
+## [1.4.0] - 2026-11-03
+
+### Adicionado
+- **Navegação por pastas.** Uma visualização Pastas, ao lado de grade e lista, mostra o que foi encontrado uma pasta por vez, como num gerenciador de arquivos: primeiro as subpastas, com número de arquivos e tamanho, depois os arquivos, sob um caminho clicável. A árvore de pastas da barra lateral navega nessa visualização, e os filtros continuam valendo.
+- **Recuperar pastas inteiras ou partes delas.** Pastas e arquivos são marcados por caixas de três estados que continuam ao navegar; uma pasta marcada leva tudo o que está dentro dela, e subpastas ou arquivos desmarcados ficam de fora. Cada pasta marcada é recriada no destino a partir dela mesma (`Documentos/Clientes/Projeto` → `Projeto/...`), com o manifesto de hashes de sempre.

 After a scan, results open in a file-manager style explorer built for thousands of items:
 
 - **Left:** navigation by type, real photo date (EXIF, by year and month), folder, camera, confidence and GPS, with an option to hide small files and duplicates.
-- **Center:** thumbnail grid or list, grouped by day or month, with virtual scrolling. A filter chip shows what is active and clears it in one click.
+- **Center:** thumbnail grid or list, grouped by day or month, with virtual scrolling, or the **Folders** view (below) to browse one folder at a time. A filter chip shows what is active and clears it in one click.
 - **Right:** details panel with the preview, folder, dates (taken, modified, created, accessed), camera, resolution and the file metadata. The badge shows the **confidence** of the file (high, medium or low).
 - **Bottom bar:** selection count and the recovery buttons. Recovery always goes to another folder and writes a manifest with MD5, SHA-1 and SHA-256.
 
 Arrow keys move through the files, and Space opens the full-screen quick look. Selection works like Finder or Explorer (Ctrl, Shift, keyboard).
 
+### Browsing by folder
+
+<p align="center"><img src="img/folders-light-en.png" width="900" alt="The Folders view: the root of the recovered files with DCIM ticked, Viagens partly ticked, the selection total at the bottom and the folder details on the right"></p>
+
+The third view button (the folder icon, next to grid and list) turns the explorer into a file manager over what was found. The center shows **one folder at a time**: its subfolders first, each with how many files and how much space it holds counting everything below it, then the files directly inside. A breadcrumb at the top (`Root › Documents › Project`) goes back up; double-click or Enter opens a folder, Backspace or Alt+↑ goes up, and clicking a folder in the sidebar tree jumps to it. Files found only by signature, which have no known folder, sit in **By signature** at the root. Filters (type, date, confidence…) still apply and change the counts.
+
+To recover, tick folders and files with their boxes; the selection survives navigation. Ticking a folder takes **everything inside it**, at any depth, even what the active filters hide. Unticking a subfolder or a file inside a ticked folder leaves the folder half-ticked and keeps that item out. The bottom bar shows the exact total, and **Recover selection** recreates each ticked folder in the destination **from itself down**: recovering `Documents/Clients/Project` writes `Project/...` with all its subfolders. Files ticked on their own go to the root of the destination, and two ticked folders with the same name become `Project` and `Project (2)`. The manifest with MD5, SHA-1 and SHA-256 is written as always.
+
+Only folders that hold at least one recovered file appear: Guará knows folders through the paths of the files it finds.

 Depois da varredura, os resultados abrem num explorador no estilo de um gerenciador de arquivos, pensado para milhares de itens:
 
 - **Esquerda:** navegação por tipo, data real da foto (EXIF, por ano e mês), pasta, câmera, confiança e GPS, com opção de ocultar arquivos pequenos e duplicadas.
-- **Centro:** grade de miniaturas ou lista, agrupadas por dia ou mês, com rolagem virtual. Uma etiqueta mostra o filtro ativo e o remove com um clique.
+- **Centro:** grade de miniaturas ou lista, agrupadas por dia ou mês, com rolagem virtual, ou a visualização **Pastas** (abaixo) para navegar uma pasta por vez. Uma etiqueta mostra o filtro ativo e o remove com um clique.
 - **Direita:** painel de detalhes com a pré-visualização, pasta, datas (tirada, modificada, criada, acessada), câmera, resolução e os metadados do arquivo. O selo mostra a **confiança** do arquivo (alta, média ou baixa).
 - **Barra inferior:** quantidade selecionada e os botões de recuperação. A recuperação sempre vai para outra pasta e grava um manifesto com MD5, SHA-1 e SHA-256.
 
 As setas navegam pelos arquivos e a barra de espaço abre a visualização rápida em tela cheia. A seleção funciona como no Finder ou no Explorer (Ctrl, Shift e teclado).
 
+### Navegando por pastas
+
+<p align="center"><img src="../img/folders-light-pt.png" width="900" alt="A visualização Pastas: a raiz dos arquivos encontrados com DCIM marcada, Viagens parcialmente marcada, o total da seleção embaixo e os detalhes da pasta à direita"></p>
+
+O terceiro botão de visualização (o ícone de pasta, ao lado de grade e lista) transforma o explorador num gerenciador de arquivos sobre o que foi encontrado. O centro mostra **uma pasta por vez**: primeiro as subpastas, cada uma com quantos arquivos e quanto espaço contém somando tudo abaixo dela, depois os arquivos que estão diretamente nela. Um caminho no topo (`Raiz › Documentos › Projeto`) volta para cima; duplo clique ou Enter abre uma pasta, Backspace ou Alt+↑ sobe, e clicar numa pasta da árvore lateral vai direto até ela. Arquivos achados só por assinatura, que não têm pasta conhecida, ficam em **Por assinatura** na raiz. Os filtros (tipo, data, confiança…) continuam valendo e mudam as contagens.
+
+Para recuperar, marque pastas e arquivos pelas caixas; a seleção continua ao navegar. Marcar uma pasta leva **tudo o que está dentro dela**, em qualquer profundidade, inclusive o que os filtros ativos escondem. Desmarcar uma subpasta ou um arquivo dentro de uma pasta marcada deixa a pasta parcialmente marcada e mantém aquele item de fora. A barra de baixo mostra o total exato, e **Recuperar seleção** recria cada pasta marcada no destino **a partir dela mesma**: recuperar `Documentos/Clientes/Projeto` grava `Projeto/...` com todas as subpastas. Arquivos marcados soltos vão para a raiz do destino, e duas pastas marcadas com o mesmo nome viram `Projeto` e `Projeto (2)`. O manifesto com MD5, SHA-1 e SHA-256 é gravado como sempre.
+
+Só aparecem pastas que contêm pelo menos um arquivo recuperado: o Guará conhece as pastas pelos caminhos dos arquivos que encontra.
