Fixes#54 — `codegraph init -i` crashes with "Fatal process out of memory: Zone"
on large codebases because all 16 tree-sitter WASM grammar modules were compiled
upfront by V8, exhausting the WASM Zone allocator.
Changes:
- initGrammars() now only initializes the tree-sitter WASM runtime (Parser.init()),
no longer eagerly loads all grammar files
- New loadGrammarsForLanguages() loads only grammars for languages actually present
in the project (e.g. a Dart project loads ~2-3 grammars instead of 16)
- Orchestrator detects needed languages after file scan, before parsing begins
- Embedding pipeline now uses quantized model (~67MB vs ~270MB) to further reduce
WASM memory pressure when embeddings are enabled
Replace native tree-sitter with web-tree-sitter + tree-sitter-wasms for
universal cross-platform support. Add node-sqlite3-wasm as a fallback
when better-sqlite3 native bindings aren't available. Move better-sqlite3
and sqlite-vss to optionalDependencies so installs never fail.
Fix installer to use npx fallback when global npm install fails, so MCP
config, hooks, and quick-start instructions all work without the bare
codegraph command in PATH.
Fix tests: update schema version expectation, fix db test paths and
method names, extract MAX_OUTPUT_LENGTH as module constant, normalize
Windows path separators in import resolver.
- Fix Float32Array embedder bug: was creating zero-filled array instead
of copying data from TypedArray-like objects
- Fix VSS search query: use subquery pattern so LIMIT applies before JOIN
- Pin tree-sitter versions: remove caret ranges for ABI stability, add
overrides to lock tree-sitter core at 0.22.4
- Lazy grammar loading: load native bindings on first use per language
instead of all at startup, so one missing grammar doesn't affect others
- Remove stale src/extraction/queries copy from copy-assets script

Adds support for Dart and Liquid languages with tree-sitter parsing.
Improves accuracy of code symbol extraction for existing languages.
Indexes project files to enhance code navigation features.
Migrates build system to facilitate code contributions.
Removes git hook functionality.
Integrates Sentry for error tracking and reporting.
Enhances project initialization and configuration loading.
The nomic-ai model is now downloaded during npm install via a postinstall
script and stored globally in ~/.codegraph/models (shared across projects)
instead of per-project in .codegraph/models.

Change static import to dynamic import() for @xenova/transformers
which is an ESM-only package. This fixes ERR_REQUIRE_ESM when
running via npx in CommonJS environments.
