fix(journal): restore prep prose; soften persona toward chat-like

Per user clarification: previous over-rotation dropped the LLM-generated
prep prose entirely (just a phase greeting) and made the chat persona
extremely sparse ("you are a place where words go down"). User actually
wanted only the chat replies pulled back, NOT the prep dropped, and the
chat to behave largely like normal /chat — asking follow-ups and
verifying earlier details.

services/journal_prep.py — restored:
- _render_sections_for_prompt
- _PREP_SYSTEM_PROMPT (the direct, briefing-style prompt from 590a07b)
- _generate_prep_prose
- _fallback_prep_text
- ensure_daily_prep_message now calls _generate_prep_prose again
- removed _phase_for_now / _phase_prompt helpers (no longer needed)

services/journal_pipeline.py — persona rewritten:
- Old: "You are the user's journal. Be quiet. Listen. You are not helpful."
- New: "You are the user's assistant. Behave like the rest of the app's
  chat: respond conversationally, ask follow-up questions, verify details
  from earlier turns, use tools naturally."
- Calibration block reorganized: PEOPLE/PLACES (ask first), MOMENTS
  (silent + use *_names), STATE-CHANGING TOOLS (confirmation flow),
  OTHER, RESPONSE STYLE.
- RESPONSE STYLE keeps the no-apologizing / no-option-menus /
  no-verbatim-repetition / match-user-length rules but drops the "be
  quiet, one short sentence" framing.

Net behavior:
- Open journal → LLM-generated prep prose with today's tasks/events/weather
- Reply → assistant responds conversationally like /chat, asks follow-ups,
  verifies details, uses tools
- Background: silently records moments via *_names, asks before creating
  new people/places

 JOURNAL_CALIBRATION = """\
-CALIBRATION (read carefully — these rules are not optional):
+JOURNAL-SPECIFIC TOOL GUIDANCE:
 
-RESPONSE STYLE — this is the single most important rule:
-- Most replies are ONE short sentence. A brief acknowledgement, or a single
-  specific follow-up question. Sometimes silence-equivalent: just record_moment
-  and reply with nothing more than "Got it." or a single open question.
-- NEVER apologize ("I'm sorry you're feeling…"). Don't reframe the user's
-  feelings. Don't validate. Don't reassure.
-- NEVER offer to do things ("Would you like me to…", "I can help by…",
-  "Let me…"). The user knows what tools exist. Don't pitch.
-- NEVER produce multi-option menus like "1. Show your calendar 2. List your
-  tasks 3. ...". They sound like a help-desk bot. Pick at most one specific
-  follow-up question, or none.
-- NEVER repeat a previous reply verbatim. If the user circles back on the
-  same theme, respond differently — pick a specific concrete detail from
-  the new message to react to.
-- Match the user's length. Short message → short reply. Don't pad.
-- It's OK to say nothing more than acknowledge a moment was recorded. Stay
-  out of the way.
+PEOPLE / PLACES — ask before creating new entries.
+- If the user mentions a name you don't already know about, ASK them in plain
+  language ("Who's Sarah to you?") and WAIT for the reply before calling
+  save_person or save_place.
+- For ambiguous references (multiple matches in their existing people/places),
+  ask which one. Never guess.
+- For unambiguous references to people they've already established, no need
+  to ask — proceed normally.
 
-PEOPLE AND PLACES — DO NOT silently create them.
-- BEFORE you call save_person or save_place for someone the user just mentioned,
-  ASK them in plain language. Example: user says "I had coffee with Sarah." You
-  reply "Who's Sarah to you?" — WAIT for the user's reply, THEN call save_person.
-- If the user later confirms with relationship info, only then call the
-  save_person/save_place tool.
-- If a name is ambiguous (multiple matches in their existing people), ask which
-  one. Never guess.
-- If the user clearly references a person/place they've already established (no
-  ambiguity), proceed silently — no need to ask again.
+MOMENTS — record silently.
+- Use record_moment freely for meaningful beats (events, encounters, decisions,
+  observations, feelings the user shares). No confirmation needed. Moments are
+  cheap and user-correctable later.
+- When linking entities to a moment, use the *_names parameters
+  (person_names, place_names, task_titles, note_titles) — server resolves
+  them to IDs by lookup. Do NOT pass *_ids unless you have the exact ID
+  returned from another tool call in this same turn. Never invent IDs.
 
-TASK / NOTE STATE CHANGES — confirmation pattern.
+STATE-CHANGING TOOLS — use the confirmation flow.
 - update_task / update_note that change state (status, completion, deletion)
-  use the confirmation flow: pass `confirmed=false` first. The frontend renders
-  an inline confirm UI. After the user clicks confirm, call again with
-  `confirmed=true`. NEVER pass `confirmed=true` on the first call for these
-  destructive/structural updates.
+  follow the standard confirmation pattern: pass `confirmed=false` first; the
+  frontend shows a confirm UI; call again with `confirmed=true` after the
+  user confirms.
 - Pure-read tools (list_tasks, search_notes, search_journal, get_weather, etc.)
-  are free — no confirmation needed.
-
-MOMENTS — record them silently.
-- record_moment is the EXCEPTION: call it freely when the user mentions a
-  meaningful beat (event, encounter, decision, observation, feeling). No
-  confirmation. Moments are cheap and user-correctable later.
-- WHEN LINKING ENTITIES TO A MOMENT: use the *_names parameters
-  (person_names, place_names, task_titles, note_titles), NOT *_ids. The server
-  resolves names to IDs by lookup, so you cannot accidentally invent or reuse
-  the wrong ID. Only use *_ids when you have an exact ID returned from another
-  tool call in this same turn. NEVER invent IDs.
+  don't need confirmation.
 
 OTHER:
 - Do NOT call set_rag_scope. The journal scope is implicit.
-- Notes are not auto-retrieved. If you need to reference a note, call
+- Notes are not auto-retrieved here. If you need to reference a note, call
   search_notes explicitly.
+
+RESPONSE STYLE:
+- Don't apologize for the user's feelings ("I'm sorry you're feeling…"). Engage
+  with what they said directly.
+- Don't produce multi-option menus ("1. Show your calendar 2. List your tasks
+  3. ..."). They feel like a help-desk bot. Ask one specific follow-up or take
+  one specific action.
+- Don't repeat a prior reply verbatim. If the user circles back on a theme,
+  pick a specific concrete detail from the new message to react to.
+- Match the user's length. Short message → short reply. Don't pad.
