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
