Add tests for repository-level instrumentation

[Copilot]

No test coverage existed for actions/instrument/repository — unlike workflow and checksuite instrumentation which already had smoke tests in test_github.yml.

Changes

• repository-smoke job: Runs the repository action with the ambient workflow_call event context, validating the always-executed path (dependency install, resource attributes, contributor count metric).

• Individual event jobs (each needs: repository-smoke): One job per event type, each passing a minimal static event_body JSON to exercise the corresponding branch in main.sh:

  Job	event_name	event_action	Code path exercised
  repository-pull-request-opened	pull_request	opened	vcs.change.count +1
  repository-pull-request-closed	pull_request	closed	no merge — vcs.change.duration
  repository-pull-request-merged	pull_request	closed	merged — vcs.change.time_to_merge
  repository-pull-request-reopened	pull_request	reopened	change state toggle
  repository-pull-request-review-submitted	pull_request_review	submitted	vcs.change.time_to_approval (approved)
  repository-create	create	—	vcs.ref.count +1
  repository-delete	delete	—	vcs.ref.count -1
  repository-push	push	—	push without base_ref (no GitHub API comparison call)

All jobs use console exporters + OTEL_SHELL_SDK_OUTPUT_REDIRECT: /dev/null; no output assertions, consistent with the checksuite-smoke pattern.

@copilot split these non smoke tests au into individual jobs

Done in 04606d2. The single repository job has been replaced with 8 individual jobs (repository-pull-request-opened, repository-pull-request-closed, repository-pull-request-merged, repository-pull-request-reopened, repository-pull-request-review-submitted, repository-create, repository-delete, repository-push), each depending on repository-smoke.

Pull request overview

Adds GitHub Actions smoke coverage for repository-level instrumentation (previously untested), aligning it with existing workflow/checksuite smoke coverage in this repo’s CI.

Changes:

• Adds a repository-smoke job that runs ./actions/instrument/repository under the ambient workflow_call context to exercise the always-executed path.
• Adds per-event jobs (all needs: repository-smoke) that run the repository action with minimal static event_body JSON to hit key branches in actions/instrument/repository/main.sh.
