chore(deps): bump claude-agent-sdk 0.2.148 -> 0.2.152

[github-actions]

Automated bump opened by the Check claude-agent-sdk version workflow.

Bumps the SDK pin in pyproject.toml from 0.2.148 to 0.2.152 and regenerates poetry.lock. Scope is deliberately limited to the pin + lock so the human reviewer owns the release coordination.

References:

• Release notes: https://github.com/anthropics/claude-agent-sdk-python/releases/tag/v0.2.152
• Full changelog: anthropics/claude-agent-sdk-python@v0.2.148...v0.2.152
• PyPI: https://pypi.org/project/claude-agent-sdk/0.2.152/

Reviewer checklist before merging:

• Bump version in pyproject.toml [tool.poetry] version and src/__init__.py
• Add a new ## [x.y.z] section to CHANGELOG.md describing this bump
• Confirm the [otel] extra is still present on the pin (the SDK unconditionally imports opentelemetry.propagate)
• Push an empty commit (git commit --allow-empty) so the test matrix fires: PRs opened with the default GITHUB_TOKEN do not trigger downstream pull_request workflow runs by design
• Confirm all CI checks pass

Mark the PR ready for review once the items above are in place.
