The chat.send handler (used by webchat and TUI) is a separate path
from the agent handler. Inject timestamp into BodyForAgent (what the
model sees) while keeping Body raw for UI display.
This completes timestamp coverage for all non-channel paths:
- agent handler: spawned subagents, sessions_send, heartbeats
- chat.send: webchat, TUI
Messages arriving through the gateway agent method (TUI, web, spawned
subagents, sessions_send, heartbeats) now get a timestamp prefix
automatically. This gives all agent contexts date/time awareness
without modifying the system prompt (which is cached for stability).
Channel messages (Discord, Telegram, etc.) already have timestamps
via envelope formatting in a separate code path and never reach
the agent handler, so there is no double-stamping risk.
Cron jobs also inject their own 'Current time:' prefix and are
detected and skipped.
Extracted as a pure function (injectTimestamp) with 12 unit tests
covering: timezone handling, 12/24h format, midnight boundaries,
envelope detection, cron detection, and empty messages.
Integration test verifies the agent handler wires it in correctly.

* fix: prefer requesterOrigin over stale session entry in subagent announce routing
When a subagent finishes and announces results back, resolveAnnounceOrigin
merged the session entry (primary) with requesterOrigin (fallback). If the
session store had a stale lastChannel (e.g. whatsapp) from a previous
interaction but the user was now on a different channel (e.g. bluebubbles),
the announce would route to the wrong channel.
Swap the merge order so requesterOrigin (captured at spawn time, reflecting
the actual current channel) takes priority, with the session entry as
fallback for any missing fields.
Error before fix:
Delivery failed (whatsapp to bluebubbles:chat_guid:...): Unknown channel: whatsapp
Adds regression test for the stale-channel scenario.
* fix: match test to exact failure scenario and improve reliability (#4957) (thanks @tyler6204)
- Remove lastTo from stale session store to match the exact mismatch scenario described in the PR
- Replace 5ms setTimeout sleeps with expect.poll for better test reliability
- Prevents flakiness on slower CI machines
