chore: clean up nolint directives in act package (#864)

Removes 88 `nolint` directives (386 → 298) via mechanical, zero-regression cleanups:

- **38 `bodyclose`** in `act/artifactcache/handler_test.go`: replaced by `defer resp.Body.Close()` after each HTTP call.
- **21 dead directives** (`gocyclo`, `dogsled`, `contextcheck`): none of these linters are enabled in `.golangci.yml`, so the directives were doing nothing.
- **29 `testifylint`** directives whose underlying issues were addressed by mechanical rewrites:
  - `assert.Nil(t, err)` → `assert.NoError(t, err)`
  - `assert.NotNil(t, err)` → `assert.Error(t, err)`
  - `assert.Equal(t, true/false, x)` → `assert.True/False(t, x)`
  - `assert.Equal(t, 0, len(x))` → `assert.Empty(t, x)`
  - `assert.Equal(t, N, len(x))` → `assert.Len(t, x, N)`
  - `assert.Len(t, x, 0)` → `assert.Empty(t, x)`

Many `testifylint` directives still apply because they flag `require-error` (i.e. testifylint wants `require.NoError` instead of `assert.NoError` for early bail-out). That's a behavior change (fail-fast vs continue) and out of scope for this purely mechanical cleanup — those can be addressed in a follow-up. Same for `expected-actual`, `equal-values`, `error-is-as`, and the remaining `nilnil` / `unparam` / `forbidigo` / `staticcheck` / `goheader` / `dupl` directives.

`golangci-lint run` is clean. Tests pass for all touched packages.
