add schedule & workflow dispatch paths. Also make prepare logic conditional (#353)

* feat: add agent mode for automation scenarios

- Add agent mode that always triggers without checking for mentions
- Implement Mode interface with support for mode-specific tool configuration
- Add getAllowedTools() and getDisallowedTools() methods to Mode interface
- Simplify tests by combining related test cases
- Update documentation and examples to include agent mode
- Fix TypeScript imports to prevent circular dependencies

Agent mode is designed for automation and workflow_dispatch scenarios
where Claude should always run without requiring trigger phrases.

* Minor update to readme (from @main to @beta)

* Since workflow_dispatch isn't in the base action, update the examples accordingly

* minor formatting issue

* Update to say beta instead of main

* Fix missed tracking comment to be false

* add schedule & workflow dispatch paths. Also make prepare logic conditional

* tests

* Add test workflow for workflow_dispatch functionality

* Update workflow to use correct branch reference

* remove test workflow dispatch file

* minor lint update

* update workflow dispatch agent example

* minor lint update

* refactor: simplify prepare logic with mode-specific implementations

* ensure tag mode can't work with workflow dispatch and schedule tasks

* simplify: remove workflow_dispatch/schedule from create-prompt

- Remove workflow_dispatch and schedule event handling from create-prompt
  since agent mode doesn't use the standard prompt generation flow
- Enforce mode compatibility at selection time in the registry instead
  of runtime validation in tag mode
- Add explanatory comment in agent mode about why prompt file is needed
- Update tests to reflect simplified event handling

This reduces code duplication and makes the separation between tag mode
(entity-based events) and agent mode (automation events) clearer.

* simplify PR by making agent mode only work with workflow dispatch and schedule events

* remove unnecessary changes

* remove unnecessary changes from PR

- Revert update-comment-link.ts changes (agent mode doesn't use this)
- Revert create-initial.ts changes (agent mode doesn't create comments)
- Remove unused default-branch.ts file
- Revert install-mcp-server.ts changes (agent mode uses minimal MCP)

These files are only used by tag mode for entity-based events, not needed
for workflow_dispatch/schedule support via agent mode.

* fix: handle optional entityNumber for TypeScript

- Add runtime checks in files that require entityNumber
- These files are only used by tag mode which always has entityNumber
- Agent mode (workflow_dispatch/schedule) doesn't use these files

* linting update
