fix(init): quote cce binary path in SessionStart hook command

[rajkumarsakthivel]

Summary

Fixes #145. On Windows, cce init writes an unquoted backslash path into .claude/settings.local.json:

"command": "C:\\Users\\fahmid\\.local\\bin\\cce.exe status --oneline"

Claude Code runs hook commands through bash (Git Bash on Windows), which interprets unquoted backslashes as escape characters. The path collapses to C:Usersfahmid.localbincce.exe and every session start fails with "command not found."

The fix reuses the existing _quote_hook_path helper from hook_installer.py (already used by the settings.json lifecycle hooks) to properly quote the path. This helper handles both POSIX (shlex.quote) and Windows (cmd-style double quotes).

One-line change. Existing projects need to re-run cce init --agent claude (or manually quote the path in settings.local.json) to pick up the fix.

Pull request overview

This PR fixes Windows session startup failures caused by an unquoted cce binary path written into .claude/settings.local.json by cce init, by reusing the existing cross-platform hook-path quoting helper.

Changes:

• Import and reuse context_engine.memory.hook_installer._quote_hook_path when generating the SessionStart “cce status” hook command.
• Quote the resolved cce binary path before appending status --oneline so Git Bash doesn’t treat backslashes as escapes.

• The idempotency check uses marker "cce status", but the command uses an absolute binary path (now also quoted), so the substring "cce status" typically won’t be present (e.g. ".../cce" or "cce.exe"), causing cce init to append duplicate SessionStart hooks on subsequent runs (especially on Windows). Use a marker that matches the stable suffix of the hook command instead (e.g. "status --oneline").

    session_hooks = hooks.setdefault("SessionStart", [])
    if not _has_cce_hook(session_hooks, "cce status"):
        session_hooks.append({
            "matcher": "",
            "hooks": [{"type": "command", "command": f"{_quote_hook_path(Path(cce_cmd))} status --oneline"}],
