Will PflegerandGitHub 114d40d9d3 feat(relay): gate kind 30178 team-catalog reads behind the shared tag (#3358 )

Team catalog projections (`kind:30178`) embed every member's system
prompt, so they need the same read gate personas already have: only the
author sees an unshared event. The gate was hardcoded to `kind:30175` at
six read surfaces plus the SQL pushdown, so rather than adding a second
special case it becomes kind-generic over `SHARED_GATED_KINDS = {30175,
30178}`.

## Kind 30178

New parameterized-replaceable kind, addressed by `(pubkey_o, 30178,
team_id)`. It embeds sanitized member projections instead of referencing
`kind:30175` heads — a foreign reader of a shared team could not
otherwise hydrate members whose own persona events are unshared or, for
built-ins, absent entirely. `kind:30176`'s wire body is untouched, so
device sync keeps its contract.

## Kind-generic shared gate

`buzz_core::kind` replaces `is_persona_shared_kind` /
`is_unshared_persona_event` / `persona_event_is_shared` with
`SHARED_GATED_KINDS` and the kind-agnostic `is_shared_gated_kind` /
`is_unshared_gated_event` / `event_is_shared`. Every read surface
consults the set:

| Surface | File |
|---|---|
| REQ historical delivery + `ids` lookup |
`crates/buzz-relay/src/handlers/req.rs` |
| Live fan-out | `crates/buzz-relay/src/handlers/event.rs` |
| COUNT fallback | `crates/buzz-relay/src/handlers/count.rs` |
| NIP-98 HTTP `/query`, `/count`, `/search` |
`crates/buzz-relay/src/api/bridge.rs` |
| Pre-`LIMIT` SQL pushdown | `crates/buzz-db/src/event.rs` |

The SQL clause generalizes from `kind != 30175` to `kind NOT IN (...)`
bound from `SHARED_GATED_KINDS`, still applied before `ORDER BY … LIMIT`
so a page of newer private events cannot starve an older shared one off
the candidate set. `EventQuery::persona_reader` is renamed
`shared_gated_reader` and `needs_persona_filtering` to
`needs_shared_gate_filtering` to match.

Because the `buzz-core` rename has consumers outside the relay, the four
desktop call sites of `persona_event_is_shared` travel with it:
`desktop/src-tauri/src/commands/personas/pending.rs`,
`desktop/src-tauri/src/event_sync.rs`, and two in
`desktop/src-tauri/src/managed_agents/persona_events.rs`. Each call is
unchanged apart from the name — the persona `shared` projection behaves
exactly as before.

## Ingest validation

`validate_persona_envelope` splits into two reusable pieces —
`validate_shared_tag` (exactly-two-element `["shared","true"]`, at most
one occurrence) and `single_bounded_d_tag` (exactly one `d` tag,
non-empty, `<=64` chars, no ASCII control characters or whitespace).
`validate_team_catalog_envelope` composes both; personas additionally
keep the slug grammar `^[a-z0-9][a-z0-9_-]{0,63}$`.

`kind:30178` deliberately does **not** get the slug grammar. Team ids
are UUIDs or built-in identifiers such as `builtin-team:welcome`, and
the colon is not slug-legal; rewriting ids to fit would break NIP-33
addressing against the team's own `kind:30176` head. The non-empty and
exactly-one checks are load-bearing regardless — without them generic
NIP-33 storage maps a missing `d` onto `(pubkey_o, 30178, "")` and every
team overwrites its predecessor.

The exact two-element `shared` shape is enforced because the SQL
visibility clause is JSONB containment (`tags @>
'[["shared","true"]]'`), which would match a three-element superset such
as `["shared","true","extra"]`.

`kind:30178` is also added to the `Scope::UsersWrite` allowlist and to
`is_global_only_kind`, so a stray `h` tag cannot channel-scope an
owner-authored definition.

## Deferred

`kind:30176` is deliberately not a gate member. Its writers never emit
`shared`, so catalog opt-in semantics do not describe it — it needs
owner-private reads driven by an authenticated principal set, tracked as
a separate follow-up.

## Tests

- 19 new `ingest.rs` unit tests covering the 30178 envelope (UUID and
colon `d` tags, 64-char boundary, non-ASCII bound,
empty/valueless/duplicate/missing `d`, embedded newline, `shared`
false/three-element/duplicate, scope and global-only membership).
- Persona regressions for the valueless `["d"]` shapes, since the
`d`-tag helper is shared by both validators.
- Existing `kind.rs` gate tests generalized and extended to assert the
gate applies to 30178 as it does to 30175.
- New `crates/buzz-test-client/tests/e2e_team_catalog.rs`: 9 WS-level
tests over a live relay covering author reads of unshared heads, foreign
omission from REQ, `ids`-lookup denial, COUNT existence-leak, share and
unshare transitions, and the mixed-kind filter case.
- `.github/workflows/ci.yml` adds `--test e2e_team_catalog` to the Relay
E2E job so the new suite runs.

## Docs

`docs/nips/NIP-AP.md` gains a "Team catalog projection: kind:30178"
section and an "Ingest validation: kind:30178" subsection, records the
gate as kind-generic, documents 30178 deletion vs. unshare semantics,
and adds a security note that sharing a team exposes every member's
instructions even when that member's own `kind:30175` head is unshared.
