[FEATURE] Reload local plugins on startup

Problem Statement

When developing plugins locally, file changes/adds are not reflected even after restarting Claude Code.

Current workflow to update plugin placed locally:

1. Bump the version in marketplace.json
2. Run /plugin (opens interactive menu)
3. Select the plugin to update

Hidden trap: If the version is not changed, the update is silently ignored with no error or warning message.

This creates unnecessary friction during local plugin development.

Proposed Solution

For plugins installed from local file-based marketplaces, automatically reload their contents when Claude Code starts, without requiring version changes.
