Merge gitea/act into act/
Merges the `gitea.com/gitea/act` fork into this repository as the `act/` directory and consumes it as a local package. The `replace github.com/nektos/act => gitea.com/gitea/act` directive is removed; act's dependencies are merged into the root `go.mod`. - Imports rewritten: `github.com/nektos/act/pkg/...` → `gitea.com/gitea/act_runner/act/...` (flattened — `pkg/` boundary dropped to match the layout forgejo-runner adopted). - Dropped act's CLI (`cmd/`, `main.go`) and all upstream project files; kept the library tree + `LICENSE`. - Added `// Copyright <year> The Gitea Authors ...` / `// Copyright <year> nektos` headers to 104 `.go` files. - Pre-existing act lint violations annotated inline with `//nolint:<linter> // pre-existing issue from nektos/act`. `.golangci.yml` is unchanged vs `main`. - Makefile test target: `-race -short` (matches forgejo-runner). - Pre-existing integration test failures fixed: race in parallel executor (atomic counters); TestSetupEnv / command_test / expression_test / run_context_test updated to match gitea fork runtime; TestJobExecutor and TestActionCache gated on `testing.Short()`. Full `gitea/act` commit history is reachable via the second parent. Co-Authored-By: Claude (Opus 4.7) <noreply@anthropic.com>
