fix+docs+release(v0.4.4): D78 — olp-connect stale strings + CDN-safe README URL + pre-publish audit (#49)

* fix+docs+release(v0.4.4): D78 — olp-connect stale strings + README CDN-safe tag URL + repo public-flip pre-audit

Patch release on top of v0.4.3. Three small issues caught when running
olp-connect for real on MacBook (D77 client-install verification):

## G11: repo visibility flip

Repo dtzp555-max/olp flipped PRIVATE -> PUBLIC during this session.
Closes the original G11 finding (anonymous curl can't fetch raw URL from
private repos). Pre-publish audit (per cc-rules pre-publish-audit.md
checklist):
- Identity scrub: 0 hits — no taodeng, no 老大, no /Users/.../ paths,
  no personal hostnames, no personal emails, no real LAN IPs (only RFC
  documentation placeholders 192.168.1.10 + 10.0.0.5)
- Credential scrub: gitleaks 'no leaks found' — all olp_ matches are
  placeholder (olp_XXXX...) or test fixtures (olp_not-a-real-key-...)
- Git history: maintainer accepted Option A (GitHub-account email already
  verified-public on profile; flip exposes nothing new)

## G11 mitigation: README curl URL CDN-cache-safe

GitHub raw CDN serves a stale 404 for /main/<file> for ~5-15min after a
private->public visibility flip (negative-cache TTL). Tag-pinned URLs
bypass this because the tag ref was never queried while private.

D78 makes README's primary olp-connect curl URL tag-pinned:
  bash <(curl -fsSL .../v0.4.4/bin/olp-connect) <ip>
with /main/ listed as alternative for trusted-head users.

## G12: detect_openclaw claimed plugin not shipped

bin/olp-connect's OpenClaw detection block said "The OpenClaw OLP plugin
(D71-D73) is NOT YET SHIPPED" — but D71-D73 shipped olp-plugin/ at
v0.4.0. Replaces stale text with real install instructions:

  git clone https://github.com/dtzp555-max/olp.git /tmp/olp-repo
  openclaw plugins install /tmp/olp-repo/olp-plugin
  # or symlink: ln -sf .../olp-plugin ~/.openclaw/extensions/olp

Points at docs/integrations/openclaw.md for the full setup with
dedicated bot apiKey + restart-gateway notes.

## G13: olp-connect self-version hardcoded literal

Pre-D78 the script declared OLP_CONNECT_VERSION="0.4.0-phase4" as a
hardcoded literal that nobody updated through v0.4.1 / v0.4.2 / v0.4.3.
D78 derives the version at runtime from sibling package.json via
python3. When invoked from a checked-out repo, version resolves to the
actual value; when curl-piped (no on-disk package.json next to script),
falls back to "unknown".

  bash bin/olp-connect --version  # -> olp-connect 0.4.4 (automatic)

## Test count

717 (v0.4.3) -> 720 (v0.4.4). +3 D78 regression tests in Suite 36:
- 36v: pins absence of NOT YET SHIPPED text + presence of real install path
- 36w: pins runtime version derivation from package.json
- 36x: pins README tag-pinned URL recommendation

## Authority

- D77 MacBook client-install verification session (2026-05-26)
- ~/.cc-rules/docs/guides/pre-publish-audit.md (the checklist that
  preceded the visibility flip)
- Process learning: every README that includes a `curl raw-URL | bash`
  install pattern should pin to a release tag (not /main/) for CDN-
  cache resilience.

## Out of D78 scope (deferred)

- F6 (doctor client-side limitation) — Phase 5 ADR amendment
- D75 reviewer P2-1 (ADR 0004 per-hop schema) + P2-2 (defensive type
  assert) — non-blocking
- scripts/migrate-from-ocp.mjs — Phase 7

* fix: D78 reviewer P2 fold-in — _resolve_version defensive guards (require /bin suffix + env-var path passthrough + nounset default)
