feat: add inline comment tool to allowed tools for code-review plugin

When the code-review@claude-code-plugins plugin is specified in agent mode
for PRs, automatically add mcp__github_inline_comment__create_inline_comment
to the allowed tools list. This ensures Claude can use the inline comment
tool once the MCP server is enabled.

Changes:
- Check for code-review plugin in agent mode prepare
- Add inline comment tool to allowed tools for PR contexts
- Tool is only added when both plugin is present and context is a PR
