loadChannelOutboundAdapter (via createChannelRegistryLoader) was reading
from getActivePluginRegistry() — the unpinned active registry that gets
replaced whenever loadOpenClawPlugins() runs (config schema reads, plugin
status queries, tool listings, etc.).
After replacement, the active registry may omit channel entries or carry
them in setup mode without outbound adapters, causing:
Outbound not configured for channel: telegram
The channel inbound path already uses the pinned registry
(getActivePluginChannelRegistry) which is frozen at gateway startup and
survives all subsequent registry replacements. This commit aligns the
outbound path to use the same pinned surface.
Adds a regression test that pins a registry with a telegram outbound
adapter, replaces the active registry with an empty one, then asserts
loadChannelOutboundAdapter still resolves the adapter.
Fixes#54745Fixes#54013
Channel plugin resolution fails with 'Channel is unavailable: <channel>'
after the active plugin registry is replaced at runtime. The root cause is
that getChannelPlugin() resolves against the live registry snapshot, which
is replaced when non-primary registry loads (e.g., config-schema reads)
call loadOpenClawPlugins(). If the replacement registry does not carry the
same channel entries, outbound message delivery and subagent announce
silently break.
This mirrors the existing pinActivePluginHttpRouteRegistry pattern: the
channel registry is pinned at gateway startup and released on shutdown.
Subsequent setActivePluginRegistry calls no longer evict the channel
snapshot, so getChannelPlugin() always resolves against the registry that
was active when the gateway booted.
