fix(ocp-cli): replace eval-curl with bash array to preserve JSON body quoting

`eval curl "$_AUTH_HEADER" "$@"` re-tokenizes its argument list according
to bash word-splitting rules. When OCP_ADMIN_KEY is set, the JSON body
`'{"name": "laptop"}'` (which contains a space) gets split into
`'{name:'` and `'laptop}'` — two separate args — so curl receives a
malformed body and the server rejects the request.

Fix: replace the `_AUTH_HEADER` string + `eval` pattern with a bash array
`_AUTH_ARGS`. Array expansion via `"${_AUTH_ARGS[@]}"` preserves word
boundaries across substitution with no eval required. Both code paths
(OCP_ADMIN_KEY env var and ~/.ocp/admin-key file fallback) and the empty
case (no admin key) are preserved unchanged.

Verified via `bash -x` trace:
  Before: `curl … -d '{name:' 'laptop}'` (body split, malformed)
  After:  `curl … -d '{"name": "testkey-pr-c"}'` (body intact, single arg)

Identified during fresh-state Round 2 testing on MacBook.

 # Changelog
 
-## v3.14.0 — 2026-05-10
-
-### Features (security hardening)
-
-- **Per-key session isolation** (PR #86, S1) — the `sessions` Map in `server.mjs` is now keyed by `${keyName}|${conversationId}` instead of bare `conversationId`. Before this fix, two clients using distinct API keys but the same `session_id` value (e.g. both defaulting to `"default"`) would share the same `cli.js` subprocess and conversation history, creating a cross-tenant leak path. Post-fix each (key, session) pair is isolated end-to-end, extending the per-key cache isolation shipped in v3.13.0 D1 to the session layer.
-- **On-disk credential file modes 0700/0600** (PR #87, S2) — `setup.mjs` now creates `~/.ocp` at mode 0700 and both `admin-key` and `ocp.db` at mode 0600. An idempotent `reconcileFileModes()` call in `server.mjs` startup tightens any existing installation to these modes automatically on every launch, so existing prod boxes fix themselves without manual `chmod`. Before this fix, all three files were created at the process's default umask (typically world-readable 0644 / 0755), leaving plaintext credentials readable by other local users.
-- **`/api/usage` default scope = self; admin all-keys requires `?all=true`** (PR #88, S3) — the usage endpoint now applies a least-privilege default: anonymous callers receive only their own rows, non-admin authenticated callers receive only their own rows, and admin callers receive only their own rows unless they explicitly pass `?all=true`. When `?all=true` is used, an audit log line is emitted. Before this fix, any admin-token holder could silently enumerate usage data for every key on the server.
-
-### Behavior changes
-
-- **Breaking change for admin tooling**: `/api/usage` no longer returns all-keys data by default. Existing cron jobs, dashboards, or scripts that rely on the admin token seeing all-keys output must add `?all=true` to their request URL after upgrading to v3.14.0.
-- **File mode reconcile at server startup** logs a one-line notice per path when mode is tightened (e.g. `[security] tightened ~/.ocp/ocp.db → 0600`). No action is required from the operator; the reconcile is idempotent and silent when modes are already correct.
-- **`sessions` Map key is now `${keyName}|${conversationId}` internally.** No client-visible wire change — the `session_id` field in request/response is unchanged.
-
-### Verification
-
-- Stress-test pass: 11/11 phases including S1/S2/S3 security regression checks (Phase E, I, J). 35-minute sustained run, 60 calls, 0 errors, 0 timeouts. RSS dropped 51→47 MB across the window. Per-key cache isolation, singleflight, cache_control bypass, quota enforcement, file-mode reconcile, and scope guard against escalation all verified against running code.
-
-### Governance
-
-- All three PRs (#86, #87, #88) include the explicit `cli.js`-citation-not-applicable disclaimer (per PR #75 pattern) since they are OCP-internal access-control, session-state, and file-permission changes with no corresponding `cli.js` operation to cite.
-
-### No new env vars / no public API surface change beyond the documented breaking change
-
-This release adds no new env vars or endpoints. The only externally visible change is the `/api/usage` scope guard (breaking for admin all-keys consumers; see Behavior changes above).

 ### Anonymous Access (optional)
 
 In `multi` mode, the admin can designate a single well-known "anonymous" key that bypasses `validateKey()` and grants public read/write access. This is useful for letting LAN users (or clients like OpenClaw multi-agent setups) connect without individual per-user keys.
 
 **Enable**:
 
-The anonymous key is wired into the service unit (launchd plist on macOS, systemd unit on Linux) at install time. Export `PROXY_ANONYMOUS_KEY` in your shell before running `setup.mjs`, and `setup.mjs` will write it into the service unit env so the auto-started proxy picks it up:
-
 ```bash
 export PROXY_ANONYMOUS_KEY=ocp_public_anon   # or any string of your choice
-node setup.mjs --bind 0.0.0.0 --auth-mode multi
+ocp start                                    # or however you start the server
 ```
 
-If OCP is already installed without it, re-export the env var and re-run `node setup.mjs` (the installer is idempotent — it refreshes the service unit). Then `ocp restart` so the running proxy picks up the new env. Setting `PROXY_ANONYMOUS_KEY` only in your interactive shell **does not** affect the auto-started proxy — the service unit is the source of truth for its environment.
-
 **Client side**: the anonymous key value is exposed via `GET /health` as the field `anonymousKey` (null when not set). Clients like `ocp-connect` can auto-discover and use it, so the end user doesn't need to get a personal key from the admin.
 
 **Security note**: setting this env var is an **opt-in** to public access — anyone who can reach your OCP endpoint can use it, up to any rate limits you configure. Don't enable this on internet-exposed OCP instances without additional protection.
