docs(framework): P4.1 — fix stale install.sh comments + cmp-equal early-exit

Non-blocking fast-follow from #590 dual-engine review:
- install.sh: PRESERVE_PATHS "(never overwritten)" and the seed-block "never be
  overwritten once customized" comments contradicted P4's framework-owned
  overwrite — clarified both (PRESERVE protects from rsync --delete; reconcile
  re-applies framework-owned with backup-once).
- reconcile (install.sh + file-adapter.ts): skip the copy when content already
  matches (cmp-equal early-exit) to avoid mtime churn. Parity preserved.

install.sh fixtures 14/14 green; gate green; prettier clean.

Refs #542, closes #592
