Name matching was creating false `calls` edges between unrelated modules
in monorepos because `findBestMatch()` had no concept of directory
proximity — functions with common names (e.g. `navigate`) in different
apps scored identically and resolved to whichever came first.
Adds path proximity scoring (shared directory segments) so same-module
candidates strongly win over cross-boundary ones, and lowers confidence
for distant matches so import-based resolution takes precedence.
Closes#67

- Fix defProc method lookup collisions when multiple classes share
method names (e.g. Create) by indexing qualified forms
- Remove overly broad 'Id' prefix filter that swallowed user-defined
symbols like Identifier or IdleTimer
- Use case-insensitive extension matching for DFM/FMX routing

Integrate main branch changes (WASM grammar architecture, centralized
resolution caches, SQLite adapter) with delphi-support branch. Pascal
grammar is now built as WASM and shipped in src/extraction/wasm/ for
consistency with the WASM-based grammar loading approach.

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.
Two major optimizations for the ref resolution phase:
1. Cache extractImportMappings() results per file path — previously
re-read and re-parsed the source file for every single ref from
that file (e.g. 100 refs from one file = 100 identical file reads)
2. Replace linear scan in matchFuzzy() with a lazily-built
case-insensitive Map index — O(1) lookup instead of iterating
all function/method/class nodes for every unresolved ref.
Also drop low-value prefix matching (confidence 0.3).

Two optimizations that eliminate the O(n²) bottleneck:
1. Add Pascal built-in filtering to isBuiltInOrExternal() — skips
resolution attempts for System.*, Vcl.*, Fmx.* and ~60 common
RTL identifiers (WriteLn, Create, Free, TObject, etc.)
2. Cache getNodesByKind() results during warm cache phase — matchFuzzy()
was calling the database 3 times per unresolved reference instead
of using the in-memory cache that warmCaches() already builds.

The resolving refs phase stalled on large projects (3400+ files, 38k+ nodes)
because matchFuzzy loaded ALL functions/methods/classes per ref, import
mappings were re-extracted per ref, and fileExists hit disk every call.
Add kindCache, lowerNameCache, importMappingCache, and knownFiles set to
warmCaches(). Rewrite matchFuzzy to use O(1) lowercase index lookup instead
of 3x getNodesByKind scans. Cache import mappings per file. Pre-build file
existence set from the index for O(1) fileExists checks.
- Add 'svelte' to Language type, DEFAULT_CONFIG includes, grammars, and config validation
- Add SvelteExtractor that extracts <script> blocks and delegates to TS/JS TreeSitterExtractor
- Add Svelte framework resolver for runes ($state, $derived, $effect, etc.), store auto-subscriptions, SvelteKit module aliases ($app/*, $env/*, $lib/*), and SvelteKit route detection
- Update README to list Svelte and Dart in supported languages

- Fix arrow function extraction: explicitly call extractFunction() for
arrow functions/function expressions in variable declarations instead
of silently skipping them (all 6 arrow function tests now pass)
- Best-candidate resolution: collect candidates from all strategies and
return highest confidence match instead of first match
- Fix graph traversal 'both' direction: correctly determine next node
for mixed incoming/outgoing edges in BFS and DFS

- SQLite performance pragmas: synchronous=NORMAL, 64MB cache,
memory temp store, 256MB mmap (safe with WAL mode)
- Batch insert for unresolved refs: single transaction instead of
N individual inserts per file
- Symbol caching (warmCaches): pre-load all nodes into memory maps
before resolution, eliminating repeated SQLite queries per ref
- Async file I/O: fs.stat/readFile in indexFile() are now non-blocking
- Denormalize filePath/language onto UnresolvedReference: avoids N
node lookups during resolution, with schema migration v2
