Add plugin entry: plan-mode

[bottlebrushes]

Summary

This adds the Plan Mode plugin (plan-mode) to the BB Community Marketplace.

Plan Mode gives any agent in BB a dedicated planning and exploration phase before it writes code, edits files, or runs commands. When active, it injects an instructional directive into the agent's turn instructions that enforces read-only codebase analysis and explicitly refuses code execution until the user switches to Implement mode.
