feat(cmake): add pinned native grammar with five-platform qualification

[harjotgill]

Purpose

Provide source-bound CMake declarations for deterministic review context. This package parses CMake syntax; it does not execute CMake, resolve dependencies, or infer active build configurations. Shared registry integration and reviewer adoption are separate dependent changes.

Changes

• Vendor unchanged MIT-licensed tree-sitter-cmake 0.7.2.post1 generated C sources with verified SHA-256 provenance.
• Add native grammar registration, offline maintainer build, smoke tests, and a five-target packaging guard.
• Add non-publishing CI qualification for Linux x64/ARM64, macOS x64/ARM64, and Windows x64; test both build-tree and installed-package layouts.
• Pin napi 0.45.3 in the pnpm lockfile. No runtime downloads, install scripts, or compiler fallback.

Validation and limits

Local build/load succeeds on Linux x64/ARM64 and macOS ARM64. Cross-compiled macOS x64 passes under Rosetta; this is not native Intel CI qualification. Product extraction checks pass on those runtimes (24 repeated controls, including a pinned public Dusk declaration). These are portability/assembly tests, not review efficacy evidence.

Frozen filtered installation, scoped Biome checks, actionlint, and whitespace checks pass. Windows has not been tested locally; require the hosted matrix before considering release. The initial Rosetta compiler-launcher failure is retained in the research record, not treated as a passing build.

No binaries are committed. No npm publish or production dependency update is included. Packaging intentionally fails without all five prebuilds. The existing upstream-delegating publication workflow is not used by this PR.

Summary by CodeRabbit

• New Features

  • Added a CMake grammar package for parsing CMake files across Linux, macOS, and Windows on supported x64 and ARM64 platforms.
  • Added platform-specific native builds and prebuilt package support.
  • Added TypeScript metadata for CMake file extensions and language registration.

• Bug Fixes

  • Added parser validation for comments, strings, variables, and malformed input recovery.

• Documentation

  • Added package usage, build, qualification, licensing, and publishing documentation.

📝 Walkthrough

Walkthrough

Adds a pinned native CMake grammar package with verified vendored sources, parser registration, offline builds, smoke tests, and required prebuild checks. Adds qualification across Linux, macOS, and Windows targets. The workflow tests both build-tree and installed-package layouts. Documentation defines parsing scope, packaging layout, licensing, and platform qualification details. Vendor files retain exact bytes on Windows.

Priority: ⬇️ Low

Merge Risk: 🟡 Moderate · up to c6684

TypeScript users following the established default-import grammar API can fail to consume the new CMake package. Align its declaration before merging.
