Adds the two cases the deep-dive flagged as untested: a receiver-based method
collision (Get/get on the same type) and the all-salted branch where no member
is the unique exported one (Run/RUN). Also adds the CHANGELOG entry.

Node ids casefold (deliberately, for AST/LLM/builder parity), but Go is
case-sensitive and uses case for visibility: exported `Run` and unexported
`run` in one file collapsed to one id, so the second was dropped by add_node
and a local `run()` call phantomed to a same-named symbol in another package.
The Go extractor now salts the non-canonical half of a same-file case-only
collision (exported keeps the stable plain id), so both survive and the
in-file resolver binds the unexported call locally. ids.py / normalize_id are
untouched, so the id contract holds and non-Go corpora are unaffected.

Prevent package-qualified calls and types from collapsing onto unrelated bare-name symbols. Preserve Go import evidence, resolve internal packages exactly, canonicalize external type stubs, and support incremental resolution context.
