fix(module): align imports with declared module path

[BinaryHusk]

Summary

This PR updates the module path and internal imports from
github.com/aanogueira/git-context to github.com/techquestsdev/git-context.

The depguard allowlist in .golangci.yml was updated as well so linting
continues to allow this module's internal imports.

This appears to be a leftover path from the previous repository location.

Reproduction

go install github.com/techquestsdev/git-context@latest

Observed:

go: github.com/techquestsdev/git-context@v1.4.2 requires go >= 1.25.0; switching to go1.25.10
go: github.com/techquestsdev/git-context@latest: version constraints conflict:
        github.com/techquestsdev/git-context@v1.4.2: parsing go.mod:
        module declares its path as: github.com/aanogueira/git-context
                but was required as: github.com/techquestsdev/git-context
