fix(journal): minimal prep + quieter persona

The prep was generating a multi-sentence recap of tasks/events/weather/
projects/recent moments via an LLM call. Per user direction, that's
redundant — the right-side widgets already show today's data — and the
verbosity made the journal feel chatty when the user wanted quiet.

Replaces the prep prose generator with a single phase-aware check-in
question (drawn from a static map: morning="How are you starting the
day?", midday="How's it going so far?", evening="How did the day shake
out?"). No LLM call. The structured `sections` are still gathered and
persisted on msg_metadata for provenance and possible future tooling
(e.g., search), they just don't render in the prep message.

Also pulls the journal persona way back. The prior framing pushed the
model toward stock therapy-template patterns ("I'm sorry you're feeling…"
+ numbered option lists). The new persona is "you are the user's journal —
listen, be quiet, stay out of the way." RESPONSE STYLE rules now lead the
calibration block and explicitly forbid:

- apologizing for the user's feelings
- offering to help / pitching tools
- multi-option menus
- verbatim repetition of prior replies
- padding short replies into paragraphs

Most replies should be one short sentence. Sometimes the right reply is
"Got it" + a record_moment tool call.
