feat(extraction): index string-literal names in generic tuple type aliases (#634) (#740)

TypeScript service/RPC contracts written as a tuple of generic types —
`type List = [Service<'query_apply_record', Req, Resp>, …]` — carry their
names only as string-literal type arguments, so static extraction never
indexed them and `codegraph query query_apply_record` returned nothing.

Add a narrow TS/TSX type-alias pass that emits each tuple entry's
string-literal name as a `method` node under the alias (qualifiedName
`List::query_apply_record`), making it searchable. Scope is limited to a
direct literal arg of a generic that is a direct tuple element, with a
valid-identifier filter — so utility types (Pick/Omit/Record), deeper
nested generics, and route paths produce no noise.

Bumps EXTRACTION_VERSION so existing indexes get a re-index hint.
