feat+test+docs: D68-D70 — bin/olp-connect + /health.anonymousKey + ADR 0011 (#43)

* feat+test+docs: D68+D69+D70 — bin/olp-connect + /health.anonymousKey + ADR 0011

Third substantive Phase 4 implementation. 3 D-days bundled per Iron Rule
11 IDR — olp-connect consumes /health.anonymousKey for zero-config
client setup, both governed by ADR 0011's trusted-LAN-only invariant.

## D68 — bin/olp-connect (zero-config client setup)

Ports OCP ocp-connect (721 lines) → OLP olp-connect (564 lines, pure bash).
Bash over Node (per ADR 0010 § Notes) because client machines may lack
recent Node; bash + curl + python3 = max portability.

CLI: `olp-connect <host-ip> [--port PORT] [--key API_KEY] [--no-system-env]
                            [--dry-run] [--help] [--version]`

Workflow:
1. Connectivity probe (curl /health, 5s timeout, distinguishes TCP
   unreachable from auth-required)
2. Auth resolution: --key flag → /health.anonymousKey (D69) → interactive
   prompt fallback
3. Smoke test (GET /v1/models with bearer)
4. IDE detection + per-IDE config:
   - Claude Code: detect + warn (NOT supported as OLP client per ADR 0010)
   - Cline: detect + print manual VSCode-settings snippet
   - Continue.dev: detect (extension OR ~/.continue/config.yaml) + write
     idempotent models: entry
   - Cursor: detect + print snippet + WARNING (per prior-art known
     base-URL fragility)
   - Aider: detect + write OPENAI_API_BASE + OPENAI_API_KEY to rc files
   - OpenClaw: detect + print "install /olp plugin (D71-D73 deliverable)"
5. System-level env: macOS launchctl setenv / Linux ~/.config/environment.d
   (so VSCode/Cursor started via Dock inherit)
6. Summary + test command

Idempotent (bracketed `# OLP LAN (added by olp-connect)` ... `# /OLP LAN`
blocks in rc files). --dry-run exercises every state-change site without
modifying anything. Exit 0/1/2 conventions.

Installed via package.json bin so `npx olp-connect` works.

## D69 — /health.anonymousKey + auth.advertise_anonymous_key

server.mjs handleHealth emits OPTIONAL `anonymousKey: "olp_..."` field
when ALL THREE prerequisites hold:
1. config.json auth.advertise_anonymous_key === true
2. config.json auth.allow_anonymous === true (per ADR 0007 § 7)
3. At least one non-revoked key has plaintext_advertise field set

Default-off: field is ABSENT (not null) — preserves v0.3.x /health shape;
existing tests don't regress.

bin/olp-keys.mjs new flags: `keygen --anonymous --advertise` writes the
plaintext into the manifest's optional `plaintext_advertise` field AND
prints a WARNING about disk-storage + /health exposure + ADR 0011
pointer. Owner-tier --advertise rejected at BOTH CLI + lib layers.

Implementation note: reused existing guest tier (no new owner_tier:
'anonymous'); plaintext_advertise is a forward-compat optional manifest
field per ADR 0007 § 4 unknown-fields-allowed convention. Cleaner than
introducing a new tier.

anonymousKey appears in BOTH trimmed AND full /health payloads — the
trimmed payload's purpose is to be readable by anonymous clients so they
can self-bootstrap. Tested.

Startup warns on prereq failure (anonymous_key_advertised_but_denied /
anonymous_key_advertised_but_no_anonymous_key_exists) so the relaxed-
posture failure mode is observable. Graceful-degrade: server still
boots; handleHealth re-checks at request time and silently omits the
field when any prereq fails (defense-in-depth).

## D70 — ADR 0011 (anonymous-key deployment-context limits)

New ADR codifying the trusted-LAN-only invariant.

Trade-off documented: anonymous key advertised via /health = anyone who
can reach the server can read /health and use the key. Acceptable ONLY
when "anyone who can reach the server" ≈ "trusted family on the LAN".
Public-internet deployment = instant compromise.

Soft enforcement: server logs startup warn if BIND_ADDRESS resolves to
a public IP AND advertise_anonymous_key: true. No hard allowlist (TLS-
fronted private networks indistinguishable from public from server's
perspective).

Re-evaluation trigger: any time OLP gains "expose to public internet"
deployment mode (e.g., Cloudflare Tunnel guidance in README), revisit.

D68-D70 line, OCP server.mjs:148/1454/1488/1555 (PROXY_ANONYMOUS_KEY
reference).

## Test count

658 → 672 (+14 D68-D70 tests across Suite 34: 5 keys.mjs unit + 6 /health
HTTP integration + 3 CLI integration).

## Scope discipline

NO /v1/messages entry surface (out of Phase 4 per ADR 0010).
NO olp-plugin/ Telegram plugin (D71-D73).
NO docs/integrations/*.md files (D71-D73).
NO CHANGELOG / package.json version bump (Phase 4 close handles versioning;
only package.json bin entry for olp-connect added).
NO new npm deps.

* fix: D68-D70 reviewer P1 + P2 fold-in — README impact note + listKeys redaction + schema_version note

Reviewer APPROVE WITH MINOR — 0 P0, 1 P1, 2 P2; all three folded in.

P1 — README impact note for new Phase 4 user-visible surfaces.

Per CLAUDE.md release_kit.new_feature_doc_expectations:
- new env / config knob → README § Environment Variables
- new endpoint or response field → README § API Endpoints
- new CLI surface → dedicated §

README now documents:
- /health.anonymousKey optional field (in API Endpoints table) with cross-
  ref to ADR 0011 + the three-prereq gate
- streaming.heartbeat_interval_ms config (D61) + auth.advertise_anonymous_key
  config (D69) under new "config.json keys introduced at Phase 4" subsection
- Operator CLI surfaces summary: olp / olp-connect / olp-keys keygen
  --anonymous --advertise, with cross-refs to ADR 0010 + 0002 Amendment 7

P2-1 — lib/keys.mjs listKeys() now strips plaintext_advertise alongside
token_hash. Callers wanting the advertised plaintext for the /health
publication path MUST go through findAdvertisedKey() — the only sanctioned
read site. Defends against a future caller of listKeys() leaking the
plaintext into logs / HTTP responses / dashboards. Tests still pass
(no in-repo caller of listKeys depends on plaintext_advertise being
present).

P2-2 — ADR 0011 now documents the schema_version-stays-at-1 decision
explicitly. Additive optional fields don't require bump per ADR 0007 § 4,
but a future archaeologist asking "why didn't D69 bump schema_version?"
now has a one-line answer. Same paragraph documents the listKeys()
redaction policy in plain text alongside the manifest-field contract.

672/672 tests still pass.
