fix(skill): use FC temp OSS for skill code packages

[117503445]

Summary

• Change ar skill create --code-dir to upload the skill ZIP to FC TempBucket OSS and create a SKILL/CODE_PACKAGE tool.
• Implement FC 2016 tempBucketToken signing with Authorization: FC ... instead of POP/CommonRequest auth.
• Send codeConfiguration.ossBucketName/ossObjectName/language/command and stop sending inline zipFile for normal create.
• Add placeholder main.py injection for skill directories that do not contain an entrypoint.
• Add unit/integration coverage and update English/Chinese docs.

Real verification

Ran a real 149 cn-hangzhou smoke test with the patched CLI:

tool_name: codeclaw-cli-fc-temp-skill-20260702195801
tool_id: 7af864e0-37c0-493d-b032-a167ee820334
status: READY

Review notes

Ran three Paseo sub-agent reviews with non-Codex providers:

• claude/opus: found missing-account-id error handling gap; fixed and added regression test.
• claude/qwen3.7-max: suggested normalizing Date header lookup; fixed.
• claude/glm-5.2: suggested FC signature golden test; added.

Tests

ruff check src/ tests/
ruff format --check src/ tests/
mypy src/agentrun_cli
pytest tests/unit tests/integration --cov=agentrun_cli --cov-fail-under=95

Result: 584 passed, total coverage 95.27%.

Pull request overview

This PR updates the ar skill create --code-dir workflow to upload skill code as a ZIP to Function Compute (FC) TempBucket OSS and create the skill as a CODE_PACKAGE tool, rather than sending an inline zipFile. It also adds FC 2016-style request signing and improves skill packaging behavior by injecting a placeholder main.py when missing.

Changes:

• Implement FC TempBucket token retrieval + OSS upload flow, and pass ossBucketName/ossObjectName/language/command in codeConfiguration for skill creation.
• Add FC 2016 Authorization: FC ... signing and helper utilities (_fc_authorization, endpoint/object-name helpers).
• Add unit/integration tests and update both English/Chinese skill docs to reflect the new code-package behavior.
