This can fix unit test github action error by removing `--extra eval`. `--extra a2a` is not needed because it's included in `test`. All tests are still passing.

This enables to re-use the ADK web interface in other contexts more easily.
For example, when having an own run-time the web interface can be exposed
for visualization during development.
Also add documentation for function.

Remove the release-please GitHub App config files and add an Actions-based
release pipeline with candidate branch strategy. This includes workflows for
cutting releases, running release-please, finalizing releases, publishing to
PyPI, and cherry-picking fixes to release candidates.

**Problem:**
While `DatabaseSessionService` already supports PostgreSQL through SQLAlchemy, there is no documentation or sample code showing users how to configure and use it.
**Solution:**
Add a comprehensive sample under `contributing/samples/postgres_session_service/` that demonstrates:
- How to configure `DatabaseSessionService` with PostgreSQL
- The auto-generated database schema (sessions, events, app_states, user_states tables)
- Connection URL format and configuration options
- A working sample agent with session persistence
### Testing Plan
**Unit Tests:**
- [x] I have added or updated unit tests for my change.
- [x] All unit tests pass locally.
This is a documentation-only change (new sample), so no new unit tests are required. Existing tests continue to pass.
**Manual End-to-End (E2E) Tests:**
Tested locally with the following steps:
1. Started PostgreSQL using `docker compose up -d`
2. Set environment variables:
```bash
export POSTGRES_URL=postgresql+asyncpg://postgres:postgres@localhost:5432/adk_sessions
export GOOGLE_CLOUD_PROJECT=$(gcloud config get-value project)
export GOOGLE_CLOUD_LOCATION=us-central1
export GOOGLE_GENAI_USE_VERTEXAI=true
```
3. Ran `pip install google-adk asyncpg greenlet` to install the required packages
4. Ran `python main.py` - session created successfully
5. Ran `python main.py` again - previous session resumed with event history
6. Verified tables and rows created in PostgreSQL (sessions, events, app_states, user_states)
### Checklist
- [x] I have read the https://github.com/google/adk-python/blob/main/CONTRIBUTING.md document.
- [x] I have performed a self-review of my own code.
- [x] I have commented my code, particularly in hard-to-understand areas.
- [x] I have added tests that prove my fix is effective or that my feature works.
- [x] New and existing unit tests pass locally with my changes.
- [x] I have manually tested my changes end-to-end.
- [x] Any dependent changes have been merged and published in downstream modules.
### Additional context
This PR adds documentation and a working sample for an already-supported feature. The DatabaseSessionService class already handles PostgreSQL through its DynamicJSON type decorator which uses JSONB for PostgreSQL.

### Link to Issue or Description of Change
- Closes: #4302
**Problem:**
`VertexAiSessionService.list_sessions()` only returns the first ~100 sessions. The `sessions_iterator` from `api_client.agent_engines.sessions.list()` is an `AsyncPager` — it implements `__aiter__`/`__anext__` for fetching subsequent pages, but the code uses a plain `for` loop which only calls `__iter__`/`__next__`, so it never fetches beyond the first page.
**Solution:**
Changed `for api_session in sessions_iterator` to `async for api_session in sessions_iterator` so the `AsyncPager` actually paginates. Updated the test mock to return an `AsyncIterableList` (supports both sync and async iteration) instead of a bare list, so the tests properly simulate real `AsyncPager` behaviour.
### Testing Plan
**Unit Tests:**
```
$ pytest tests/unittests/sessions/
115 passed, 1 warning in 2.25s
```
The existing `test_list_sessions`, `test_list_sessions_with_pagination`, and `test_list_sessions_all_users` all continue to pass with the updated mock.

Sessions were being erroneously cached and reused across different asyncio event loops, causing "Event loop is closed" in environments with transient loops. This updates the session caching to be loop-aware: before reusing a cached session, check that the stored loop matches the current loop. Also, if session is disconnected and loops do not match, discard the cached entry without calling aclose().
