feat: add bot_id input to handle GitHub App authentication errors (#534)

Browse Source 
Adds a new optional bot_id input parameter that defaults to the github-actions[bot] ID (41898282). This resolves the "403 Resource not accessible by integration" error that occurs when using GitHub App installation tokens, which cannot access the /user endpoint.

Changes:
- Add bot_id input to action.yml with default value
- Update context parsing to include bot_id from environment
- Modify agent mode to use bot_id when available, avoiding API calls that fail with GitHub App tokens
- Add clear error handling for GitHub App token limitations
- Update documentation in usage.md and faq.md
- Fix test mocks to include bot_id field

This allows users to specify a custom bot user ID or use the default github-actions[bot] ID automatically, preventing 403 errors in automation workflows.

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.
