feat(tools): add Shell Script (Bash/Sh) Formatter

[rishima17]

Description
A formatting tool for shell scripts to enforce consistent indentation and style. Ideally includes basic linting for common pitfalls (like missing quotes around variables).

Rationale
Shell scripts are often "quick and dirty". Having a quick way to pretty-print and check them prevents production bugs in deployment scripts.

Expected Behavior
Input area for shell code.
"Format" button to beautify code.
Basic linting warnings (e.g., SC2086 "Double quote to prevent globbing").
Implementation Tasks
Create shellFormatter.tsx.
Integrate a library like shfmt (WASM version if available) or use a beautifier logic.
Add syntax highlighting for Shell scripts.

Hi @rishima17, I’d like to work on this issue.

My plan is to create a shellFormatter.tsx component, integrate shfmt (WASM version if available) for formatting, and add basic linting warnings (like SC2086). I’ll also include syntax highlighting for shell scripts.

Please let me know if this approach aligns with the project’s direction or if you’d prefer any adjustments.
Happy to get started once I have your confirmation!
