fix(plugins): plugin manifest check misses paths that differ only in case #3158

Component

Scripts (scripts/plugins/Sync-PluginManifest.ps1)

Bug Description

Sync-PluginManifest.ps1 compares plugin.json with the derived manifest using -ne (line 829) and the component lists with -notin (lines 462-463). Both ignore case, so after a component file is renamed to a different case, plugin.json keeps the old path. -Check reports it in sync and sync leaves it alone, though that path no longer exists on a case-sensitive file system.

Expected Behavior

-Check reports a path that differs only in case as drift, and npm run plugin:sync rewrites it to the tracked casing.

Steps to Reproduce

1. Commit .github/agents/pkg/Code-Review.agent.md in a plugin, run npm run plugin:sync, and commit plugin.json.
2. git mv the file to code-review.agent.md and commit.
3. Sync-PluginManifest.ps1 -Check prints Plugin manifest and catalog are in sync and exits 0; sync prints plugin.json is already current.
