Ports the #645/#608 chained-receiver mechanism to Pascal/Delphi — which I'd
previously mis-scoped as blocked. The paren'd chained form extracts fine; it just
hit the chained-call gap like the others (with a decoy, `TFoo.GetInstance().DoIt()`
mis-resolved to a same-named method on an unrelated class).
- pascal.ts: getReturnType reads the method's `typeref` (a `function GetInstance:
TBar` returns TBar; an interface return `IFoo` is captured too).
- tree-sitter.ts: extractPascalCall now re-encodes a chained call `TFoo.GetInstance().DoIt`
(the exprDot's receiver is an exprCall) instead of collapsing it to bare `DoIt`.
Gated on the Delphi type-naming convention (`TFoo`/`IFoo`) so a capitalized
VARIABLE chain (Pascal capitalizes locals too — `Curve.X().Y()`, `Self.X().Y()`)
stays bare and keeps its existing bare-name resolution.
- name-matcher.ts: `pascal` joins the dotted-chain gate + CHAIN_LANGUAGES +
CONSTRUCTS_VIA_BARE_CALL (a `TFoo(x)` typecast yields a TFoo). When the factory's
return type wasn't captured (a `constructor Create` has no `: TBar` but returns
its class), resolve the method on the factory class itself. resolveMethodOnType
validates, so a wrong inference yields no edge.
Validation: 4 synthetic tests (factory+decoy, constructor chain, typecast chain,
absent-method safety). Real-repo A/B on PascalCoin (772 files): +19 / -18 — 15 of
the -18 are correct class→interface retargets (`GetInstance(): IAsn1OctetString`
resolves `.GetOctets` on the declared interface, not baseline's concrete-class
guess); 3 are negligible drops (0.02%). EXTRACTION_VERSION 15->16. Full suite green.

Splits the monolithic tree-sitter.ts (3,358 lines) into modular files:
- 14 language config files under src/extraction/languages/
- 3 standalone extractors (Liquid, Svelte, DFM)
- Shared helpers and types modules to avoid circular imports
Also fixes a bug where Java's extractImport hook incorrectly set
handledRefs: true, preventing unresolved reference creation and
degrading codegraph_explore results for Java codebases.
