Default session and artifact services to in-memory when running in Cloud Run/Kubernetes (or when agents_dir isn’t writable) to prevent startup failures from attempting to create .adk under read-only/unwritable container paths (e.g. /app/agents/.adk). Local development defaults are unchanged.
- ADK_FORCE_LOCAL_STORAGE=1 to always use .adk defaults
- ADK_DISABLE_LOCAL_STORAGE=1 to always avoid local storage
If local artifact initialization raises PermissionError, fall back to in-memory and log a warning

The `adk create` command now checks if the provided agent name is a valid Python identifier. An invalid name, such as one containing hyphens, will raise a `click.BadParameter` error before any files are created.

Before Python 3.10, asyncio.Queue() required a running event loop at creation time. This was deprecated in 3.8-3.9 and fully removed in 3.10. ADK requires Python 3.10+, thus remove this unecessary logic

Final part of https://github.com/google/adk-python/discussions/3605.
This change introduces:
- A new `adk migrate session` CLI command to run database schema upgrades.
- A migration script to upgrade from the old Pickle-based session schema (v0) to the new JSON-based schema (v1).
- A migration runner that orchestrates the upgrade process, handling sequential migrations and using temporary SQLite databases for intermediate steps if needed.
- Unit tests for the v0 to v1 migration.

This change modifies `load_dotenv_for_agent` to first capture the environment variables already set in the process. After loading the `.env` file with `override=True`, it restores the values of these initially set variables, ensuring that explicitly set environment variables are not overwritten by the `.env` file. A new environment variable, `ADK_DISABLE_LOAD_DOTENV`, is also introduced to completely skip the `.env` loading process

This change modifies the /run_sse endpoint to split events that contain both content and an artifactDelta. The original event is split into two separate SSE events: one containing only the content (with artifactDelta cleared) and another containing only the artifactDelta (with content cleared)
