chore(deps): regenerate artifacts for napi 3.9.0 bump

Rebuilding the code-validator guest host crate with napi/napi-derive 3.x
makes
api build emit a generated loader (host/index.js) alongside the
already-ignored host/index.d.ts. Both are build artifacts: the canonical
loader/types live in src/code-validator/guest/index.{js,d.ts}, so ignore
host/index.js in .gitignore and .prettierignore for consistency.

Also prune the now-orphaned convert_case 0.10.0 entry from the guest
Cargo.lock (only napi-derive 2 pulled it in; napi-derive 3 uses 0.11.0).

Verified on Linux+KVM: TS suite (2505) and analysis-guest Rust tests
(124) pass, including the previously-failing mcp/module-store runtime
integrity checks; prettier, tsc, and guest clippy/fmt are clean.
