v0.5.0: visible "✓ LARRY UPDATED" banner at startup

When self_update() actually did something (phase A synced files, or phase B
self-replaced + relaunched), print a green/bold box at REPL startup with
the from→to versions and file count. Stays silent when nothing happened.

Phase B now also passes LARRY_PREV_VERSION across the exec relaunch so the
new script can report the prior version, not just "updated to 0.5.0".

Verified locally against file:// base URL: first launch shows
  ═══════════════════════════════════════════════════════════════
    ✓  LARRY UPDATED
       first-run sync at v0.5.0 (34 files synced from manifest)
  ═══════════════════════════════════════════════════════════════
Second launch is silent (.last-sync-version matches running LARRY_VERSION).
