chore: expand gitignore, document PKGBUILD deps, fix branch ref

- .gitignore: add compile_commands.json, language server caches
  (.ccls-cache, .cache/clangd), and tag files (ctags, cscope)
- PKGBUILD: add per-dependency comments explaining purpose (SRP auth,
  Warden emulation, MPQ extraction, shader compilation, etc.)
- PKGBUILD: fix source branch from main → master (matches remote HEAD)
