Describe the bug

The CLAUDE_APP_BOT_ID constant in src/github/constants.ts is set to 41898282, which is actually the ID for github-actions[bot], not claude[bot].

The correct ID for claude[bot] is 209825114.

Evidence

Verified via GitHub API:

{"id": 41898282, "login": "github-actions[bot]", "type": "Bot"}
{"id": 209825114, "login": "claude[bot]", "type": "Bot"}

Looking at action.yml, the defaults are:

• bot_id: "41898282" ← WRONG (this is github-actions[bot])
• bot_name: "claude[bot]" ← Correct name, but mismatched with ID

Impact

When commits are made via git CLI (fallback when API commit signing fails), the commits have:

• Author: 41898282+claude[bot]@users.noreply.github.com
• This creates an identity mismatch and results in unsigned commits

Compare to correctly-signed commits made via GitHub API:

• Author: 209825114+claude[bot]@users.noreply.github.com
• Committer: GitHub <noreply@github.com>
• These are verified/signed by GitHub

Reproduction

1. Enable use_commit_signing: true in a workflow
2. Trigger Claude to make a commit
3. In some cases, commits fall back to git CLI instead of API
4. These commits show as unsigned in GitHub

Workaround

Explicitly set the correct bot_id in workflow:

- uses: anthropics/claude-code-action@v1
  with:
    use_commit_signing: true
    bot_id: "209825114"  # ← Workaround: correct claude[bot] ID

Suggested Fix

Update src/github/constants.ts:

// Before (incorrect)
export const CLAUDE_APP_BOT_ID = 41898282;

// After (correct)
export const CLAUDE_APP_BOT_ID = 209825114;

And update the default in action.yml:

bot_id:
  description: "GitHub user ID to use for git operations"
  required: false
  default: "209825114"  # claude[bot] ID

This may be related to #281 / #282 (commits not verified), though those issues focus on when git CLI is used rather than the incorrect bot ID.
