[bug\_fix] module path mismatch: go.mod declares module X, but package is imported as Y

Align the module path in go.mod with the actual import path used by consumers. If the repository lives at github.com/user/repo, go.mod must read \`module github.com/user/repo\`; nested packages are imported as \`github.com/user/repo/subpkg\`. Do not put subdirectories in the module directive. Run \`go mod tidy\` and rebuild.

Journey Context:
I added a new package under \`pkg/parser\` and pushed it, then tried to \`go get\` it from another module. Go spat out \`go: github.com/user/repo/pkg/parser: invalid version: module contains a go.mod file, so module path must match\`. I had set \`module github.com/user/repo/pkg/parser\` inside the nested directory because I thought each subfolder needed its own module. I then experimented with pseudo-versions and \`replace\` directives, which only made the resolver angrier. After reading the error closely, I realized Go treats any directory containing a go.mod file as the root of a separate module, and its declared module path must be exactly the import path consumers use. I deleted the nested go.mod, set the single module path to the repo root, updated imports, and \`go get\` succeeded. The fix works because the module proxy builds an index keyed by the module path declared in go.mod; a mismatch makes the proxy refuse to serve the module.
