chore: add golangci-lint, GitHub Actions CI, and pre-commit hooks
Adds .golangci.yml (errcheck, govet, staticcheck, revive, gocyclo,
gocritic, nilerr, errorlint, etc.). Fixes all lint issues found:
- RpcError/wrapRpc renamed to RPCError/wrapRPC (revive var-naming)
- Shadow vars resolved in process.go, outline.go, project.go
- nilerr suppressed with justifying comments in git/collect.go and
auto/detector.go (WalkDir / intentional empty-returns)
- if-else chain rewritten as switch in format.go (gocritic)
- gofmt applied to detector.go and client.go
Adds .github/workflows/ci.yml: lint (ubuntu), build+vet+test matrix
(ubuntu/windows/macos), and Roslyn helper build (windows). Validated
with actionlint (0 issues).
Adds .githooks/pre-commit + pre-commit.ps1 for local pre-commit checks.
