[AAASM-3537] ✨ (examples): Add Agno tool-policy example (re-land on master)

[Chisanan232]

What changed

Adds the python/agno-tool-policy/ example to the canonical master branch, plus its shared wiring:

• .github/workflows/verify-python.yml — new agno-tool-policy CI job
• root README.md — Agno gallery row under the Python table
• python/README.md — matching table row

Why

The Agno tool-policy example originally landed via PR #151, which was merged into the stale main branch by mistake. main is ~491 commits behind the repo's actual default branch master, where every other example lives. So python/agno-tool-policy/ existed on main but was missing from master.

This PR re-lands the example on the correct canonical master branch. The example directory was brought over verbatim from main; the shared entries were re-added against master's current versions (not main's stale copies) so nothing else regresses.

How to verify

cd python/agno-tool-policy
uv sync --extra dev
uv run pytest tests/ -v     # 6 passed
uv run python src/main.py    # allow get_weather/summarize_docs, deny execute_sql

The uv.lock was refreshed against the current python-sdk master tip (which ships the merged Agno adapter), so import agent_assembly.adapters.agno resolves. Smoke passes (6/6) and the adapter imports cleanly locally.

Closes AAASM-3537.
