fix: Windows git clone failures — URL reinstall + pipe deadlock + file lock (#2726)

Three fixes for Windows E2E failures:

1. cm_cli reinstall_node(): URL-based node specs used the full URL
   as lookup key, but internal dicts are keyed by repo basename or
   cnr_id. Use get_cnr_by_repo() for CNR-aware lookup with correct
   is_unknown flag.

2. git_helper.py gitclone(): disable tqdm progress when stderr is
   piped (sys.stderr.isatty() gate) to prevent pipe buffer deadlock.
   Also move stale directories from previous failed clones into
   .disabled/.trash/ before cloning (GitPython handle leak on Windows).

3. try_rmtree(): 3-tier deletion strategy for Windows file locks:
   retry 3x with delay, rename into .disabled/.trash/, then lazy-delete
   via reserve_script as final fallback.
