fix(tui): a null message_id on the first hook fire must not disarm the F1 guard

Residual found by the independent reviewer's second pass, by PROBING the fixed code rather
than reading it — the F1 fix was correct but its ARMING could be skipped entirely.

TuiDeltaAssembler.messageId was initialized to `null`. A first MessageDisplay payload carrying
message_id:null therefore compared EQUAL to the sentinel, registered no boundary, and left
`messages` at 0. When the real boundary then arrived, `else if (this.messages > 1)` evaluated
1 > 1 === false, so restartedAfterEmit never armed, and the `released` branch forwarded the
auth banner to the client — the exact leak F1 closed, reachable again through a single null
field. parseDeltaChunk does not validate message_id, so such a payload does reach push().

Two changes, both narrowing:
  - messageId now initializes to a Symbol sentinel, which is === to nothing a JSON payload can
    produce, so the first fire ALWAYS registers as message 1 whatever its message_id is.
  - the boundary branch drops the `this.messages > 1` sub-condition. It bought nothing and was
    the sole cause. The real invariant is "a boundary occurred while emitted !== ''" — which is
    unrecoverable regardless of how many messages have been seen — and that is now what the
    code says.

Whether claude ever emits message_id:null is unverified (the observed contract has it present),
so this is defense-in-depth, not a live bug. But the guard is the mechanism this feature
nominates as its primary safety property; it should not be disarmable by a field's absence.

Mutation-tested: restore the null sentinel + the messages>1 condition and the new test fails;
with the fix, 317 passed / 0 failed (was 316).

Class B (ADR 0007, OCP-owned TUI spawn) — cli.js does NOT perform this operation.

-// Resolved LAZILY, on first getDb() — not at module top-level. Two reasons, and the second is
-// the bug this fixes:
-//
-//  1. Merely IMPORTING keys.mjs should not, as a side effect, create directories in the
-//     operator's home.
-//  2. OCP_DIR_OVERRIDE exists so the test suite can point the key store at a scratch dir — and
-//     because ESM hoists imports, a top-level `const OCP_DIR = ...` here would be evaluated
-//     BEFORE an importing module's body could set the env var. Eager resolution made the
-//     override unsettable in the one place that needs it. (test-features.mjs carried a comment
-//     claiming it could "set env before the first getDb() call" — it could not, because nothing
-//     here ever read an env var. So `npm test` wrote real, UNREVOKED api_keys rows into the
-//     operator's live ~/.ocp/ocp.db: two per run, unbounded — 737 junk keys against 12 real ones
-//     on the maintainer's host — and two concurrent runs raced one file, which is the ~1-in-6
-//     flake in `listKeys includes quota fields`.)

-// comment describing an intention that nothing enforces). A production server runs without
-// NODE_ENV, so it CANNOT honor the override, however the variable got into its environment
