clawbot 877fb2c0c5 Split Dockerfile into lint + build stages for faster CI feedback (#152) ...

## Summary

Splits the Dockerfile into separate lint and build stages to provide faster CI feedback on formatting and lint issues.

### Changes

**Dockerfile:**
- **Lint stage** (`golangci/golangci-lint:v2.10.1`, pinned by sha256): Runs `make fmt-check` and `make lint` using the official golangci-lint image which has the linter pre-installed. No more downloading golangci-lint on every build.
- **Build stage** (`golang:1.25-alpine`, pinned by sha256): Runs `make test` and `make build`. Same alpine image as before.
- **Runtime stage**: Unchanged.

**Makefile:**
- Added `fmt-check` target for standalone gofmt checking.
- Refactored `check` target to use `fmt-check`, `lint`, `test` as dependencies instead of inline commands. Still works identically for local use.

### Benefits
- Lint failures surface immediately without waiting for golangci-lint download
- Uses official pre-built golangci-lint image instead of manual binary download
- Cleaner separation of concerns between lint and build stages
- `make check` still runs everything sequentially for local development
