Address review feedback: log a warning when the stale call reaper
fails to end a call instead of silently discarding the error.

Adds a periodic reaper that automatically ends calls older than a
configurable threshold. This catches calls stuck in unexpected states,
such as notify-mode calls that never receive a terminal webhook from
the provider.
New config option:
staleCallReaperSeconds: number (default: 0 = disabled)
When enabled, checks every 30 seconds and ends calls exceeding the
max age. Recommended value: 120-300 for production deployments.

Address review feedback: the in-memory deletion of initialMessage is
not persisted to disk, which is acceptable because a gateway restart
would also sever the media stream, making replay impossible.

Pre-generates TTS audio for the configured inboundGreeting at startup
and serves it instantly when an inbound call connects, eliminating the
500ms+ TTS synthesis delay on the first ring.
Changes:
- twilio.ts: Add cachedGreetingAudio storage with getter/setter
- runtime.ts: Pre-synthesize greeting TTS after provider initialization
- webhook.ts: Play cached audio directly via media stream on inbound
connect, falling back to the original TTS path for outbound calls
or when no cached audio is available

Bare numeric Discord IDs (e.g. '1470130713209602050') in cron
delivery.to caused 'Ambiguous Discord recipient' errors and silent
delivery failures.
Adds normalizeDiscordOutboundTarget() to the existing Discord
normalize module (channels/plugins/normalize/discord.ts) alongside
normalizeDiscordMessagingTarget. Defaults bare numeric IDs to
'channel:<id>', matching existing behavior.
Both the Discord extension plugin and standalone outbound adapter
use the shared helper via a one-liner resolveTarget.
