fix(git): refine deno formatting hook with config and update options

Key Changes Made:

* Removed --ext flag - Now uses deno fmt without extensions to respect deno.json
* Expanded file detection - Checks for .ts .js .tsx .jsx .md .json .jsonc (what Deno actually formats)
* Skip duplicate markdown formatting - Deno projects don't need separate Prettier for markdown since deno fmt handles it
* Better logging - More accurate messages about what was formatted

No deno.json Changes Needed! The hook will now:

* Respect exclude patterns
* Use existing fmt and lint configurations
* Work with existing deno task fmt and deno task lint commands
