Wes 5511b56fcf fix(relay): exclude ephemeral activity from message quota (#7736)
## Summary

Stop charging ephemeral WebSocket activity against the per-minute
`Messages` quota. Presence, typing, and observer traffic should not
consume the allowance intended for persistable event attempts.

- Use the existing `buzz_core::kind::is_ephemeral` predicate (kinds
`20000..=29999`) at the second admission gate. All authenticated
EVENT/REQ/COUNT traffic still consumes the shared `WsEvents` budget
first. Non-ephemeral EVENT attempts remain charged, including attempts
later rejected by authorization or validation.
- Add bounded `bucket` labels (`messages`, `ws_operations`, `api_calls`)
to `buzz_admission_rejections_total`. HTTP changes are metric labeling
only. Wire rejection text remains byte-for-byte unchanged, preserving
existing client parsers.
- Add real-Redis admission regressions and select them in the existing
relay integration CI job. No quota increases, identity/keying changes,
client changes, new limiter, or deployment. Downstream authorization and
fail-closed Redis behavior are unchanged.

### Related issue

Duplicate search found overlapping work: open #4912 and closed #4902.
They propose the same ephemeral-accounting correction alongside broader
wire/client/config changes. The relay fix is a deliberately narrower
four-file implementation on the current admission module, with
metrics-only diagnostics and real-Redis regression coverage. A separate
test-only CI repair is documented below. It does not close or claim to
supersede those PRs.

Related symptom: #7411. This PR does **not** resolve subscription bursts
exhausting the shared WS budget; that budget is intentionally preserved.
It also does not establish or fix the cause of HTTP quota exhaustion.

### Testing

Validation ran against base `779af8886caae1317b4de962082429867ab61503`
plus the exact patch now committed as
`70ea0528594e25e6dcb40cd74620bd5ef0177592` (binary diff SHA-256
`5064e1cbb87ecb9eff10336bae14b912cac442e1edc247aa4f093de30e4f9717`).
Normal commit/push hooks subsequently passed on the committed head,
without bypass.

Passed:
- Independent review and rerun: 11 rejection tests (including real
Redis) plus 4 admission tests. Covers ephemeral range boundaries,
human/agent budgets, persistable events, ephemeral admission after
message exhaustion, mixed EVENT/REQ/COUNT flood exhaustion, Redis
outage, exact wire payloads, and bucket metrics. Three mutations were
caught: reintroducing ephemeral billing, exempting stored events, and
bypassing WS rejection.
- `just test-unit`: all 17 runner groups; `just test-integration`: all 3
runner groups. Auth integration reported no tests; ignored database
integration tests are not claimed as executed.
- Relay all-target Clippy, formatting, workflow actionlint,
pre-commit/signoff hooks, and all applicable pre-push lanes
(`push-head-scope`, `branch-skew`, `file-size-check`, `rust-tests`,
`desktop-tauri-checks`).
- Release relay/CLI/admin build and isolated release-binary workflow:
channel creation, signed root/reply sends, exact-ID readback, and thread
retrieval. Debug and release WS smoke admitted three presence events
with a Messages limit of two, admitted two persistable events, rejected
the third, still admitted presence afterward, and rejected author
mismatch. Debug Prometheus confirmed `bucket="messages"`.

**Outstanding validation gap:** the additional `cargo test -p buzz-relay
--no-fail-fast` run was not green: library 1,055 passed / 2 failed / 100
ignored; binary 13 passed / 1 ignored; boot integration 9 passed.
Failures were
`api::mesh_demo::tests::demo_join_forwarded_arm_round_trips_echo` (504
instead of 200) and
`telemetry::tests::trace_context_lookup_does_not_enable_callsites`
(tracing assertion). Neither failure was diagnosed or repaired in this
scope, and this PR does not claim a fully green package suite. `just ci`
was not run locally; hosted CI remains to validate the PR.

All runtime tests used isolated local services. Owned services have been
stopped; nothing was deployed and no production data was touched.


### CI cancellation-test repair

At the original relay head, hosted Rust unit tests failed on the
pre-existing cancellation harness race tracked in #4945. With owner
authorization, this PR now adapts the one-file repair from #5003
(original commit `cc8dc6124957acfd67fe2336396b58e0ff43ec60`), preserving
author credit. #5003's old hosted workflows failed without starting
jobs; their status is not used as validation evidence.

Commit `55fe5f16618a51d03ad48d6f2f97b2f8b463607a` holds the fake
provider response until a successful cancellation acknowledgement, then
replays all pre-acknowledgement usage/prompt frames in order. It retains
the cancellation and usage-before-response assertions and explicitly
requires prompt completion. No production code changes in this
follow-up.

Validation on parent `70ea052859` plus this test patch, before the
pre-commit-only assertion wrapping: full `cargo test -p buzz-agent
--no-fail-fast` passed (715 tests, one ignored); 100 targeted
repetitions passed with four concurrent workers; all-target buzz-agent
Clippy passed. The unmodified parent also passed 50 local repetitions,
so this is not claimed as a local reproduction of the intermittent CI
failure. The synchronization defect was confirmed from the source,
original CI log, and #4945. Hosted CI must validate the updated head.

Independent source review cleared exact commit
`55fe5f16618a51d03ad48d6f2f97b2f8b463607a`. Normal pre-commit/signoff
and all applicable pre-push hooks passed without bypass. The original
relay-package mesh-demo and telemetry failures remain disclosed above
and were not modified by this test-only repair.
