Summary

Jira: https://jiraeu.epam.com/browse/EPMCDME-15769

Hooks written into an installed extension (~/.codemie/claude-plugin/hooks/hooks.json) kept pointing at a removed codemie, because BaseExtensionInstaller.install() returned early on already_exists and never looked at the hooks again. Every Claude Code start then showed a SessionStart hook error and no CodeMie hooks ran.

Changes

• hook-command.ts: new hasStaleCodemieCommand / repairStaleHooksCommandTree. They match only a leading absolute codemie path (or the Windows quoted node.exe + codemie*.js pair, including paths with spaces) that is missing on disk. Bare codemie, relative paths and other programs are left alone.
• BaseExtensionInstaller: the already_exists branch now calls repairStaleHooks. It reads hooks.json and does an existsSync per command, and only calls resolveCodemieBinary() when something is stale. It writes only when the tree changed, skips quietly when hooks.json is missing (Kimi), and never rewrites to a bare codemie fallback.
• resolveHookCommand is unchanged, so migration 006 and codemie-code.plugin.ts behave as before. This applies to every extension that goes through BaseExtensionInstaller.

Impact

Before: install at path A, remove A, install again gives already_exists and hooks still point at A. After: hooks are rewritten to the current codemie; a path that still exists is untouched and hooks.json is not written.

Checklist

• Self-reviewed
• Manual testing performed (lint, typecheck, --project unit and --project cli pass; mutation check: removing the repair makes the new tests fail; replayed the reported case with the built CLI's ClaudePluginInstaller on a test HOME: hooks are repaired, a valid path is left untouched)
• Documentation updated (if needed) (none needed)
• No breaking changes (or clearly documented)
