Liang Wu 89ef39998b fix(live): Buffer tool calls and emit them together upon turn completion
The `receive` method now accumulates function calls from multiple `LiveServerMessage` instances. These accumulated tool calls are yielded as a single `LlmResponse` containing all function call parts only when a turn_complete message is received.

Without the change, the tool_1's response is sent to the model as soon as it's generated, triggering a second call for tool_2. Upon receiving two consecutive tool_2's responses, the model utters the same message twice.
Fixes issue #4902

Lusha Wang dff4c44040 fix: Update agent_engine_sandbox_code_executor in ADK
1. For prototyping and testing purposes, sandbox name can be provided, and it will be used for all requests across the lifecycle of an agent
2. If no sandbox name is provided, agent engine name will be provided, and we will automatically create one sandbox per session, and the sandbox has TTL set for a year.
If the sandbox stored in the session hits the TTL, it will not be in "STATE_RUNNING" so a new sandbox will be created.

Haiyuan Cao 223d9a7ff5 feat: Agent Skills spec compliance — validation, aliases, scripts, and auto-injection
Close gaps between ADK's Agent Skills implementation and the public
Agent Skills spec (agentskills.io/specification):

- Frontmatter: add field validators for name (kebab-case, max 64),
  description (non-empty, max 1024), compatibility (max 500);
  add allowed-tools alias; add extra='allow'; add populate_by_name
- utils: extract _parse_skill_md helper; use model_validate() for
  alias support; enforce name-dir matching; add validate_skill_dir()
  and read_skill_properties()
- prompt: accept Union[Frontmatter, Skill];
- skill_toolset: add scripts/ resource loading; auto-inject system
  instruction (with inject_instruction opt-out); duplicate name check;
  _list_skills() returns Skill objects
- sample agent: remove manual instruction (auto-injected now)

Sahaja Reddy Pabbathi Reddy bef3f117b4 feat: Bigquery ADK support for search catalog tool
Merge https://github.com/google/adk-python/pull/4171

**Problem:**
The BigQuery ADK tools currently lack the ability to search for and discover BigQuery assets using the Dataplex Catalog. Users cannot leverage Dataplex's search capabilities within the ADK to find relevant data assets before querying them.

**Solution:**
This PR integrates a new search_catalog_tool into the BigQuery ADK. This tool utilizes the dataplex catalog client library to interact with the Dataplex API, allowing users to search the catalog.

**Unit Tests:**

- [x] I have added or updated unit tests for my change.
- [x] All unit tests pass locally.

Added the screenshots of the manual adk web UI tests - https://docs.google.com/document/d/1c_lMW7NYGKuLAvPFmSkLehbqySeNyXQIhzQlvo3ixmQ/edit?usp=sharing

Google Team Member 6a53f414d3 chore: set a maximum number of rows for BigQuery query results in the sample agent
The `BigQueryToolConfig` now sets `max_query_result_rows=50` explicitly to showcase this particular configuration.

Hiroaki Sano 657acfadbb docs: Add PostgreSQL session storage sample and documentation
Merge https://github.com/google/adk-python/pull/3926

### Link to Issue or Description of Change

**1. Link to an existing issue (if applicable):**

- Related: #3916

**2. Or, if no issue exists, describe the change:**

**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.

Files added:
- contributing/samples/postgres_session_service/README.md - Comprehensive guide
- contributing/samples/postgres_session_service/agent.py - Sample agent
- contributing/samples/postgres_session_service/main.py - Usage example
