Patrick Buckley f64c3e7b10 feat(storage): persist _source + _reminders side-channels on conversations
Adds two TEXT-NULL columns to the conversations table so multi-tab /
multi-device replay sees the same metacognitive bubble shape the
originating tab saw live.  Until now, reminders lived only on the
in-memory ChatSession.messages dict, and the wake-driven empty user
turn was not persisted at all (skip at session.py:2685-2686) — a
second tab connecting via /history saw the assistant turn with no
preceding wake context, and missed every other tab's reminder
bubbles besides.

Single Alembic revision 050 (head was 049) adds:
  * conversations._source — today only "system_nudge" for wake rows
  * conversations._reminders — JSON-encoded reminder list

Both backends (sqlite + postgresql) thread the columns through
save_message / save_messages_bulk / load_messages.  reconstruct_messages
unpacks the row tuple as 9 elements (was 7), JSON-decoding _reminders
on the user AND tool branches with the same contextlib.suppress guard
the existing provider_data / tool_calls decode uses.  Tool-row
reminders ride the same column so tool_error / repeat replay shape
matches user-channel parity.

session.py:2685-2686 wake-row persist skip is dropped; _append_user_turn
JSON-encodes user_msg["_reminders"] and passes both source + reminders
to save_message.  The tool-message save site at session.py:3014-3020
mirrors with metacog_reminders.

Plan reference: docs/design/watch-card-ux.md §4 Steps 1-5 (Commit 1).
