Subject: [PATCH 1/3] chore: add golangci-lint with new-from-merge-base
 baseline
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Configure golangci-lint v2 with the standard linter set (errcheck, govet,
ineffassign, unused) plus forbidigo, which enforces the Ginkgo/Gomega-only
test convention from .agents/coding-style.md by rejecting stdlib testing
calls (t.Errorf, t.Fatalf, t.Run, ...). staticcheck is disabled — the
codebase has many pre-existing QF-style suggestions not worth gating on.

issues.new-from-merge-base = master makes the lint job a gate for new
issues only; the ~1300 pre-existing baseline stays visible via
'make lint-all' for incremental cleanup. CI runs 'make lint'.

Backends needing C/C++ headers we don't install in the lint runner are
excluded via a deny list in the Makefile (backend/go/{piper,silero-vad,
llm}, cmd/launcher). Discovery still flows through 'go list ./...', so
new packages are scanned automatically.

To make backend/go/{sam3-cpp,stablediffusion-ggml,whisper} typecheckable,
move their .cpp/.h sources into cpp/ subdirs (matching qwen3-tts-cpp /
acestep-cpp). Without this 'go list' rejects the package because Go does
not allow .cpp alongside .go without cgo.

Fix two real bugs found by lint in tests/integration/ (run only via
'make test-stores', not default CI): a stale zerolog reference left over
from the slog migration (c37785b7) and an unused 'os' import.

 ## Documentation
 
 The project documentation is located in `docs/content`. When adding new features or changing existing functionality, it is crucial to update the documentation to reflect these changes. This helps users understand how to use the new capabilities and ensures the documentation stays relevant.

Subject: [PATCH 2/3] ci(lint): generate proto sources and fetch full history

The lint job was failing for two reasons:

- pkg/grpc/proto/*.go is generated, not checked in. Several packages
  import it, so without 'make protogen-go' typecheck fails project-wide
  with "no required module provides package github.com/mudler/LocalAI/
  pkg/grpc/proto".

- golangci-lint's new-from-merge-base needs to git-merge-base the PR
  against master, but actions/checkout's default shallow clone doesn't
  fetch master. fetch-depth: 0 brings full history; the config now
  references origin/master (the remote-tracking branch that survives
  the shallow checkout) instead of bare master (which doesn't exist
  locally after checkout).

core/http/app.go has //go:embed react-ui/dist/*. The glob must match at
least one non-hidden entry or typecheck fails the whole core/http
package. We don't need the real React bundle to lint Go code, so just
touch an empty index.html to satisfy the embed.
