`pkga.FuncX(...)` cross-package calls in Go monorepos were dropping
through the import resolver — `isExternalImport(go)` flagged any
non-`/internal/` import as third-party because the resolver had no idea
what the project's own module path was. Resolution fell back to name
matching with path-proximity scoring, which on a layered codebase picks
one accidental candidate per call site (~<1% recall per #388's
5,303-vs-1 figure).
- `src/resolution/go-module.ts` (new) parses the `module ...` directive
from project-root `go.mod`, exposed via `getGoModule()` on
`ResolutionContext`.
- `isExternalImport(go)` treats `<module-path>/...` imports as in-module;
the existing `/internal/` escape hatch is preserved for repos without
a parsed go.mod.
- `resolveViaImport` gets a Go cross-package branch that strips the
module prefix to a project-relative directory, then resolves the
qualified member via `getNodesByName(member)` filtered to that exact
directory and `isExported=true`. Sub-packages don't collide with their
parents; same-name funcs in different packages don't false-merge.
- Go extractor sets `isExported` from the identifier's first character
(Go's universal uppercase=exported convention). The resolver depends
on this to filter candidates.
Validation on gRPC-Go (1,031 .go files, layered package tree):
total `calls` edges: 23,803 -> 34,105 (+43%)
cross-pkg `calls`: 10,880 -> 19,929 (+83%)
fmt/strconv/etc. stdlib calls: stay external (no false positives)
Tests cover in-module disambiguation with same-name funcs in two
packages, aliased imports, and stdlib calls not being false-resolved to
in-project nodes.
Closes#388.
