* feat: add ssh_signing_key input for SSH commit signing
Add a new ssh_signing_key input that allows passing an SSH signing key
for commit signing, as an alternative to the existing use_commit_signing
(which uses GitHub API-based commits).
When ssh_signing_key is provided:
- Git is configured to use SSH signing (gpg.format=ssh, commit.gpgsign=true)
- The key is written to ~/.ssh/claude_signing_key with 0600 permissions
- Git CLI commands are used (not MCP file ops)
- The key is cleaned up in a post step for security
Behavior matrix:
| ssh_signing_key | use_commit_signing | Result |
|-----------------|-------------------|--------|
| not set | false | Regular git, no signing |
| not set | true | GitHub API (MCP), verified commits |
| set | false | Git CLI with SSH signing |
| set | true | Git CLI with SSH signing (ssh_signing_key takes precedence)
* docs: add SSH signing key documentation
- Update security.md with detailed setup instructions for both signing options
- Explain that ssh_signing_key enables full git CLI operations (rebasing, etc.)
- Add ssh_signing_key to inputs table in usage.md
- Update bot_id/bot_name descriptions to note they're needed for verified commits
* fix: address security review feedback for SSH signing
- Write SSH key atomically with mode 0o600 (fixes TOCTOU race condition)
- Create .ssh directory with mode 0o700 (SSH best practices)
- Add input validation for SSH key format
- Remove unused chmod import
- Add tests for validation logic
Clarifies which permissions are currently used (Contents, Pull Requests, Issues) versus those requested for planned future features (Discussions, Actions, Checks, Workflows).

* feat: skip permission check for GitHub App bot users
GitHub Apps (users ending with [bot]) now bypass permission checks
as they have their own authorization mechanism.

* feat: add allow_bot_users option to control bot user access
- Add allow_bot_users input parameter (default: false)
- Modify checkHumanActor to optionally allow bot users
- Add comprehensive tests for bot user handling
- Improve security by blocking bot users by default
This change prevents potential prompt injection attacks from bot users
while providing flexibility for trusted bot integrations.
