Add Strands Agents hook to common AI provider
## Summary
Add [AWS Strands Agents](https://strandsagents.com/) as a new agent backend
for `AgentOperator` and `@task.agent` in the common AI provider, building on
the `BaseAIHook` contract.
- Introduce `StrandsHook` (shared Strands SDK integration) and
`StrandsGeminiHook` as the first backend (`conn_type`: `strands-gemini`,
default connection ID: `strands_default`)
- Wire toolsets through `_tool_spec_to_native`, converting `ToolSpec`
instances to Strands-native tools
- Add skills support end-to-end: `SkillSpec` dataclass on `BaseAIHook`,
`skills` / `skills_params` on `AgentRunRequest` and `AgentOperator`, and
Strands `AgentSkills` plugin integration for filesystem paths and inline skill
definitions
- Register the new connection type in `provider.yaml` /
`get_provider_info.py` and add optional dependency:
```bash
pip install 'apache-airflow-providers-common-ai[strands]'
```
(`strands-agents[gemini]>=1.0.0`)
- Add example DAGs (`example_strands.py`) covering basic operator usage,
skills, inline `SkillSpec` + SQL toolset, direct hook usage, and `@task.agent`
- Document connection setup, hook usage, and operator skills in new/updated
RST pages
### Depends on
BaseAIHook PR https://github.com/apache/airflow/pull/67438
---
## Follow-ups
### Durable execution for Strands (`durable=True`)
`StrandsHook` currently sets `supports_durable=False`. A follow-up PR should
mirror the pydantic-ai durable path so Strands agents can resume from cached
steps on task retry.
**Out of scope for this PR:** usage limits for Strands hooks.
### Skills for Pydantic AI (`pydantic-ai-skills`)
`PydanticAIHook` currently leaves `supports_skills=False`, so
`AgentOperator.skills` / `skills_params` only work with Strands backends in
this PR. A follow-up should wire the same operator-level skills API to
pydantic-ai via the
[`pydantic-ai-skills`](https://github.com/DougTrajano/pydantic-ai-skills)
library (Agent Skills / [agentskills.io](https://agentskills.io) spec with
progressive disclosure).
