Kidus Abebe d3b80ca247 feat: add Nix flake for reproducible dev environment (#238) ...

* feat: add Nix flake for reproducible dev environment

- flake.nix with devShell (Node.js 24, pnpm, oxlint, Playwright, gh)
- nix/checks.nix for hermetic lint/typecheck/test via nix flake check
- shell.nix for backward compat, .envrc for direnv integration

* fix: use corepack for exact pnpm version pinning
- corepack reads packageManager field from package.json
- --install-directory to writable .corepack/bin (Nix store is read-only)
- COREPACK_ENABLE_DOWNLOAD_PROMPT=0 for non-interactive downloads
- Remove checks.nix (sandboxed pnpm install infeasible)
- Fix stale check to use .modules.yaml
- Remove Playwright from Nix (let pnpm manage)
- Pin shell.nix to flake-compat rev from flake.lock

* chore: address review feedback on Nix dev shell

- Remove unused lib and stdenv function arguments
- Replace no-op PLAYWRIGHT_SKIP_BROWSER_DOWNLOAD env var with comments
  documenting why we don't use Nix-provided browsers and the NixOS
  system library limitation
- Make pnpm install non-fatal in shellHook so the shell still opens
  cleanly if the lockfile is stale
- Improve staleness check readability (use -f guard instead of
  2>/dev/null redirect)
