fix: simplify and correct branch operation tests

- Remove tests for non-existent cleanupBranch function
- Fix mock setup to match actual setupBranch signature (Octokits not Octokit)
- Update assertions to match actual BranchInfo return type
- Simplify tests to avoid executing actual shell commands
- Add comprehensive test coverage for branch naming and context handling

 The OIDC token is required in order for the Claude GitHub app to function. If you wish to not use the GitHub app, you can instead provide a `github_token` input to the action for Claude to operate with. See the [Claude Code permissions documentation][perms] for more.
 
-### Why am I getting '403 Resource not accessible by integration' errors?
-
-This error occurs when the action tries to fetch the authenticated user information using a GitHub App installation token. GitHub App tokens have limited access and cannot access the `/user` endpoint, which causes this 403 error.
-
-**Solution**: The action now includes `bot_id` and `bot_name` inputs that default to Claude's bot credentials. This avoids the need to fetch user information from the API.
-
-For the default claude[bot]:
-
-```yaml
-- uses: anthropics/claude-code-action@v1
-  with:
-    anthropic_api_key: ${{ secrets.ANTHROPIC_API_KEY }}
-    # bot_id and bot_name have sensible defaults, no need to specify
-```
-
-For custom bots, specify both:
-
-```yaml
-- uses: anthropics/claude-code-action@v1
-  with:
-    anthropic_api_key: ${{ secrets.ANTHROPIC_API_KEY }}
-    bot_id: "12345678" # Your bot's GitHub user ID
-    bot_name: "my-bot" # Your bot's username
-```
-
-This issue typically only affects agent/automation mode workflows. Interactive workflows (with @claude mentions) don't encounter this issue as they use the comment author's information.
