feat(gemini): add Gemini plugin to marketplace

[amondnet]

Summary

• Adds the Gemini plugin to the marketplace via a git-subdir source pointing to pleaseai/gemini-plugin-cc at subdirectory plugins/gemini (ref: main)
• Adds a new Gemini section in README.md with a description and install instructions
• Adds the /plugin install gemini@pleaseai install line to the quick-start install list in README.md

Changes

• .claude-plugin/marketplace.json — new gemini entry with category ai, keywords, and git-subdir source configuration
• README.md — new Gemini section under the plugin listing and added install line to the quick-start block

Test Plan

• Verify marketplace.json is valid JSON with the new entry
• Confirm the git-subdir source resolves correctly: pleaseai/gemini-plugin-cc → plugins/gemini
• Run claude plugin validate .claude-plugin/marketplace.json to validate the manifest
• Test install: /plugin install gemini@pleaseai

Code Review

This pull request adds the Gemini CLI integration plugin to the marketplace configuration and updates the README with installation instructions. The review feedback focuses on correct categorization, suggesting that the Gemini plugin be moved from the 'Built-in Plugins' section to the 'External Plugins' section in the documentation. There are also suggestions to refine the metadata labels and clarify that the installation command is intended for the interactive shell.
