Replace REST-based Discord liveness probe with local WebSocket/heartbeat
state detection. REST success doesn't prove Gateway event delivery — a
half-closed WebSocket can leave Bot.start() alive while REST returns 200.
Now samples ready/open/ACK state and heartbeat latency; consecutive
unhealthy samples emit one retryable fatal code so GatewayRunner rebuilds
the adapter through the existing reconnect path.
Also fixes three lifecycle gaps in the recovery path:
1. asyncio.wait_for() can remain blocked if adapter cleanup swallows
cancellation — now uses bounded asyncio.wait() with task detachment.
2. Multiplexed secondary-profile adapters had no profile-scoped reconnect
owner — now uses one runner-owned reconnect slot per profile.
3. An in-flight turn could send its final text through the disconnected
adapter after a replacement was registered — now resolves the live
same-profile replacement for unsent final responses only (message IDs
never migrate, edits/deletes stay on the old transport).
Adds an opt-in Linux/systemd event-loop watchdog (gateway.systemd_watchdog_seconds,
default 0) for the failure mode where the whole asyncio loop stops making
progress and no in-process liveness task can run. stdlib-only sd_notify,
Type=notify/WatchdogSec generation, READY/STOPPING lifecycle.

With the mode-conditional check centralized, default (websocket) Feishu
no longer counts as port-binding in the secondary batch report — pin the
fixture to connection_mode=webhook so the test still exercises the
multi-platform report path.
Feishu was unconditionally listed in _PORT_BINDING_PLATFORM_VALUES,
causing the multiplexer to reject ALL Feishu secondary profiles. But
Feishu in websocket mode (the default) uses an outbound WebSocket
connection and does NOT bind an HTTP port — only webhook/callback mode
needs a listener.
Add _platform_binds_port() helper that checks connection-dependent
platforms (currently only Feishu) against their actual config before
raising MultiplexConfigError. Feishu websocket profiles are now allowed;
Feishu webhook profiles still raise as before.
Fixes#52563
_adapter_credential_fingerprint only looked at adapter.token directly,
but Discord (and similar) adapters store the bot token on their config
sub-object, not on self. Every Discord adapter in a multiplexed
gateway therefore returned None, the same-token conflict check was
silently skipped, and N adapters all polled the same bot token —
producing a per-message race where whichever adapter won the GIL
answered the user.
Adds a config-token fallback (token, then bot_token) so the check
actually fires for config-backed adapters. Direct adapter.token
still takes precedence when both exist.
Tests cover: config-backed token produces a fingerprint, distinct
tokens produce distinct fingerprints, direct token wins over config,
config without token attributes returns None.

Bring up adapters for every profile the gateway serves, not just the active
one. Keeps self.adapters as the default/active profile's map (the ~93 existing
self.adapters[...] sites are untouched) and adds secondary profiles under
self._profile_adapters[profile][platform].
- _start_secondary_profile_adapters loops profiles_to_serve(multiplex=True),
skips the active profile (handled by the primary startup loop), and for each
other profile loads its gateway config and creates+connects its enabled
adapters under that profile's _profile_runtime_scope (home + secret scope).
- Each secondary adapter gets _make_profile_message_handler(profile): stamps
source.profile (when unset) before delegating to the shared _handle_message,
so the agent turn and session key resolve to that profile.
- Same-platform credential-conflict detection: _adapter_credential_fingerprint
hashes the adapter's bot token (salted, truncated — never logs the token);
two profiles claiming the same (platform, token) refuse the duplicate with a
clear error naming both, since one token can't be polled twice.
- Port-binding hard-error: a SECONDARY profile that enables a port-binding
platform (webhook, api_server, msgraph_webhook, feishu, wecom_callback,
bluebubbles, sms) is a config error and aborts startup via MultiplexConfigError
— the default profile owns the single shared HTTP listener and serves every
profile through the /p/<profile>/ prefix, so a second bind can only collide.
Distinct from a transient connect failure (which logs + stays alive to retry):
a config error writes gateway_state=startup_failed and exits cleanly with an
actionable message (names the profile, the platform, and the fix). There is no
valid reason to bind a second port once you've opted into a multiplexer.
- Shutdown tears down secondary adapters alongside the primary ones.
- Defensive getattr guards keep partial-construction unit tests (stop(),
_run_agent on bare instances) working.
No-op when multiplex_profiles is off (self._profile_adapters stays empty).
Tests: fingerprint stability/log-safety/distinctness, profile message-handler
stamping (and not overriding an already-stamped source), port-binding hard-error
raises + names the profile/platform, non-binding platform is not rejected, and
the guard set covers every TCP-binding adapter.
