#683 hooks: rollover _find_repo_root fails loud + edit_gate soft entry-count guard (#664 follow-up).

Two hardening items surfaced during #664 that @memory could not touch (cross-branch edit gate blocked it).

ITEM 1 — _find_repo_root fail-loud (lifecycle/rollover.py). The PreCompact rollover hook's _find_repo_root() returned None SILENTLY when AIPASS_HOME/cwd was wrong -> rollover no-ops invisibly (the exact silent-skip that hid #664 for months). Now logs a logger.error with the AIPASS_HOME value + cwd before returning None (still degrades, just visibly).

ITEM 2 — edit_gate soft entry-count guard (security/edit_gate.py). edit_gate enforced per-entry CHARACTER caps but not entry COUNTS, so a branch could drift past its count cap between rollovers. New _check_section_counts warns (NEVER blocks) when a rolling section exceeds its cap, reading the SAME memory.config.json rollover caps @memory uses (config_loader.section('rollover') -> per_branch/defaults -> count); wrapped so a config-import failure degrades silently.

Built by @hooks, verified by devpulse: 70 tests green (+14 incl never-blocks guarantee, boundary cases, per-branch override, import-failure resilience); LIVE repro proves item1 logs the error on a bad root and item2 warns over-cap (20/15) without blocking; config structure confirmed to match memory's real caps (not inert).

Rides PR#659 (issue-clearing, no main-merge). Source: #664 verify (S292).
