Completes Swift in the #750 chained-call series (after Java #751, Kotlin #752,
C# #753, conformance #754). Two parts:
1. Swift chained-call resolution (the #645/#608 mechanism): capture Swift return
types (positional, member types -> last segment), encode capitalized-receiver
chains `Foo.make().draw()` / `Foo(args).draw()`, resolve+validate via the
shared matchDottedCallChain (+ constructor branch). Fixes the decoy wrong-edge
bug where a chained method dropped to a bare name and attached to a same-named
method on an unrelated class.
2. Nested-type extension naming fix: `extension KF.Builder: KFOptionSetter` parsed
as a class_declaration named `KF.Builder` (dot) — inconsistent with the type's
own declaration `KF::Builder` (name `Builder`) — so the extension's conformances
and members were invisible to a chained call on the type. A Swift resolveName
now names a nested-type extension by its last segment (`Builder`), so its
`implements`/`extends` edges and methods are found by the supertype walk
(conformance #754) and the simple-name method match.
Validated: synthetic decoy + args + constructor + absent-method tests; full suite
green; nested-extension repro (`KF.url().onSuccess()` resolves via conformance to
the protocol method). Real-repo A/B vs main (conformance) — Alamofire and
Kingfisher both **0 added / 0 removed, node count unchanged**: NEUTRAL and SAFE.
The prior -168 Kingfisher regression (from the naming inconsistency) is eliminated;
Swift's unique-named fluent methods already resolved by bare name, so the chain
path lands the same edges — the value here is decoy-collision correctness, the
nested-extension naming fix, and consistency with the other four languages.
EXTRACTION_VERSION 9 -> 10.

Extends AST parsing to identify and extract individual enum members/cases for better code analysis. Adds enumMemberTypes configuration to each language extractor with language-specific node types (e.g., 'enum_variant' for Rust, 'enum_case' for PHP, 'enum_entry' for Swift/Kotlin). Implements flexible member name resolution supporting both field-based and identifier-based extraction patterns.
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.
