feat(relay): Phase 4 thread lifecycle — handoff threads, semantic renames, reply_to context, hello command manifest (#71624)

- RelayAdapter.create_handoff_thread → one op-gated thread_create op
  (Discord channel thread / Telegram forum topic / Slack named seed root);
  None fallback contract preserved for the handoff watcher.
- RelayAdapter.rename_thread → thread_rename with only_if_current_name
  no-clobber guard on the wire (connector enforces; Telegram guarded
  renames fail safe). The native semantic-rename lane
  (_is_discord_auto_thread_lane) lights over the relay via the
  connector-stamped auto_thread_created/auto_thread_initial_name markers
  parsed onto SessionSource in _event_from_wire.
- reply_to {text, author, is_own} wire parse onto the SAME MessageEvent
  reply-context fields native adapters populate.
- gateway/relay/command_manifest.py: the gateway-declared slash-command
  manifest (native Discord tree mirror) sent on the DISCORD hello; the
  connector reconciles Discord's global registration (additive field,
  older connectors ignore).
- Contract doc §OutboundAction ops + Phase 4 semantics sections.
- 12 new tests (tests/gateway/relay/test_relay_threads.py); relay suite
  266 passed.

**`thread_create` / `thread_rename` (Phase 4 thread lifecycle).** One
platform-abstract pair covers handoff threads, Telegram DM/forum topics, and
LLM-title semantic renames. `thread_create`: Discord posts a channel thread
(type 11) or a message-anchored thread when `message_id` is set; Telegram
`createForumTopic` (topic id returned); Slack posts a NAMED seed root
message and returns its `ts` (threads there are message-anchored — an
explicit `message_id` anchor is echoed back verbatim). The created id rides
`SendResult.thread_id`. `thread_rename`: Discord PATCHes the thread channel;
Telegram `editForumTopic`. The **`only_if_current_name` no-clobber guard**
is the native adapters' human-rename-wins semantics, enforced
CONNECTOR-side: Discord reads the current name first and no-ops (structured
`success:false`) on mismatch; Telegram has no topic-name read, so a GUARDED
rename is unsatisfiable and fails safe (unguarded renames proceed). Slack
does not advertise `thread_rename` (a root message's text is content, not a
name). WhatsApp advertises neither (no threads).
**Auto-thread markers + gateway-declared command manifest (Phase 4
inbound/handshake).** When the connector's auto-thread egress policy creates
a Discord thread, later inbound events from that thread carry
`source.auto_thread_created: true` + `source.auto_thread_initial_name` — the
connector-observed evidence that lights the gateway's semantic-rename lane
(the LLM session title renames the thread via a GUARDED `thread_rename`;
per-instance memory, so in an N>1 fleet a miss simply never lights the
lane). The gateway may also declare its slash-command set on the Discord
`hello` frame (`command_manifest: [{name, description, options?}]`); the
connector reconciles Discord's GLOBAL application-command registration
against it (GET → diff → bulk PUT overwrite; idempotent, debounced,
best-effort — a registration failure never affects the handshake). Commands
still dispatch through the passthrough plane as before; the manifest only
keeps Discord's registry in sync with what the gateway's dispatcher handles.
**Inbound `reply_to` enrichment (Phase 4).** A platform reply may carry
`reply_to: {text?, author?, is_own?}` alongside `reply_to_message_id` — what
the user QUOTED, populated only from data the connector already had in hand
(Discord's inline `referenced_message`, Telegram's inline
`reply_to_message`, WhatsApp `context.from` + a bounded per-instance
inbound-text cache for the text leg). Absent fields mean the platform didn't
carry the data — never triggers an extra platform API call. `is_own` = the
quoted message was authored by the fronted bot (same evidence as the
`is_reply_to_bot` relevance marker). The gateway maps these onto the same
MessageEvent reply-context fields native adapters populate.
**`typing` `content?` (Slack status clear).** A `typing` frame normally omits
`content` — the connector renders its platform's active indicator ("is
typing…" Assistant status on Slack, one-shot typing elsewhere). An **empty

"""Gateway-declared slash-command manifest for the relay lane (Phase 4).
The native Discord adapter registers its slash commands directly on the
Discord command tree (`_register_slash_commands`,
plugins/platforms/discord/adapter.py) it holds the bot token. Over the
relay the CONNECTOR holds the token, so the gateway DECLARES the same
command set on its `hello` frame (`command_manifest`) and the connector
reconciles Discord's global application-command registration against it
(gateway-gateway `DiscordCommandRegistrar`: GET diff bulk PUT,
idempotent, best-effort).
This module is that declaration: the single source of truth for what the
relay lane advertises. It MIRRORS the native tree same names, same
descriptions so a user moving between a native-Discord deployment and a
hosted/relay one sees the same command palette. Interactions come back over
the passthrough plane and are normalized by
RelayAdapter._discord_interaction_to_event into the same "/name args"
COMMAND events the dispatcher already routes, so declaring a command here
requires NO new handler the dispatcher's existing slash surface is the
handler.

Discord option objects passed through verbatim. Names must satisfy
