metamon 91799405aa fix(gateway): hint Slack/Discord channels at the prior auto-reset session
Salvaged from PR #36220, ported onto the current SessionStore (SQLite-
backed get_or_create_session; activity check is last_prompt_tokens) and
the sidecar-note reset path (context notes now ride turn_sidecar_notes
instead of prepending to context_prompt).

Long-lived Slack/Discord channels/threads lose their context on
daily/idle session resets, and the agent can bind a new request to an
unrelated recent session (observed: a Discord thread reset caused a PR
in the wrong repository). Record prev_session_id when an auto-reset
replaces a session with real activity, persist it, and append a
deterministic one-line hint to the auto-reset context note pointing the
agent at session_search for that specific prior session. No LLM calls,
no channel-history APIs, no extra DB lookups; other platforms and
activity-free resets are untouched.

"""Tests for the lightweight Slack/Discord channel session-continuity hint.
Salvaged from PR #36220 (metamon-p), ported onto the current SessionStore.
Covers:
- SessionStore records the previous session_id on auto-reset (and only then).
- prev_session_id survives a to_dict() → from_dict() roundtrip (gateway restart).
- build_channel_continuity_note() emits a hint only for Slack/Discord sessions
that were auto-reset with real prior activity, and stays silent otherwise.
