chore: final pre-submission polish for JOSS

- Add CITATION.cff for GitHub citation support and Zenodo/JOSS integration
- Fix ossim reference URL in references.bib (was pointing to unrelated repo)
- Remove broken favicon reference from index.html (no public/ directory exists)
- Add meta description to index.html
- Fix sidebar title inconsistency: "Process Simulator" → "Process Scheduler Simulator"
- Rebuild dist.tar.gz with production assets

 # Summary
 
-The **Process Scheduler Simulator (PSS)** is an open-source, browser-based interactive tool designed to help students, instructors, and practitioners understand and compare classical CPU scheduling algorithms from the field of Operating Systems (OS). PSS runs entirely client-side — no server, no installation — making it instantly accessible via any modern web browser at [https://pss.lucasrguerra.dev.br](https://pss.lucasrguerra.dev.br).

 Users define a set of processes, each with an arbitrary sequence of alternating CPU and I/O bursts, and select one of eight scheduling algorithms. The simulator then executes the schedule tick by tick, rendering a live Gantt chart and computing a comprehensive set of performance metrics for each process and for the simulation as a whole. PSS supports First Come First Served (FCFS), Shortest Job First (SJF), Shortest Remaining Time First (SRTF), Round Robin (RR), non-preemptive and preemptive Priority Scheduling (with optional aging), Highest Response Ratio Next (HRRN), and Multilevel Queue scheduling.

 # State of the Field
 
 Several browser-based and desktop scheduling simulators exist. OS-sim [@ossim] offers a graphical simulation of a full operating system, including scheduling, but targets upper-division students and requires local installation. The CPU Scheduling Simulator by Mitchell [@mitchelljava] is a Java desktop application that covers a subset of algorithms without I/O burst modeling. Web-based tools such as Process Scheduling Simulator by Nikhil Anand cover FCFS, SJF, and RR, but do not support aging, HRRN, or Multilevel Queue, and lack composable I/O burst sequences.
 
-PSS distinguishes itself in three key ways. First, it models **full CPU-I/O burst sequences** for each process, rather than a single CPU burst, enabling simulation of realistic workloads and the CPU Bound vs. I/O Bound classification. Second, it implements a broader set of algorithms — including HRRN and Multilevel Queue with per-queue quantum — than most comparable tools. Third, the entire application is deployed as a **static single-page application** with no backend dependency, enabling one-click access and offline use via Docker, which lowers the barrier for classroom adoption.
