Capture tasks, with one intake seam mail can call later (#130)

A task is not a fact and not a note. A fact is a claim about the world that a
correction supersedes; a note is something to recall by meaning. A task is work
with a lifecycle, and the read that matters is "everything outstanding right
now" — which over an append-only log would mean replaying history on every
question. So: a tasks table, migration #14, statuses candidate/open/done/dropped
that each move forward exactly once.

Dedupe is on normalised text among LIVE rows only, via a partial unique index.
That is the property the mail side needs: an extractor may call CaptureTask for
every message it reads, as often as it likes, without growing the list — while a
weekly errand is still capturable again once the last one is done.

Three ways in, one seam. ipc.CaptureTaskReq is it: the voice path
(router.ParseTaskCapture on an explicit marker — "добавь в задачи …", never
"надо бы поспать"), the /tasks form, and the email reader from #246 when it
exists. Mail-derived items set Source "email:<account>", Status "candidate" and
Evidence to whatever makes the row reviewable; a candidate is inert until he
confirms it on /tasks, and Maven names it as unconfirmed when she recites the
list rather than putting words in his mouth.

No new intent — the router enum is a contract with the relabelling prompt, so
capture rides the note intent and the list rides a query source, both matched
deterministically like the calendar and plan matchers already are.

Nothing here speaks. No tick rule reads tasks; the list is answered when asked
about, which is why /tasks POST is not step-up gated the way /tools and
/routines are — a task write moves no boundary.

 6. Wire voice query — `"что я обычно делаю?"` routes to `IntentQuery` → behavior profile lookup → LLM-phrased answer
 7. Add IPC read method `MethodGetBehaviorProfile` so mavweb can display it on `/dash`
 8. Test with synthetic fact history — verify weekly schedule is correctly inferred
+
+---
+
+## Status (2026-08-01) — partially shipped, deliberately narrowed
+
+Shipped on `overnight/behavior-profile`:
+
+- `internal/memory/behavior.go` — `BuildProfile` counts habits per weekday out of
+  self-facts: distinct-day counts (`MinHabitDays = 2`), a median time-of-day, and
+  `FormatWeekdayRU` / `FormatOverallRU` for the spoken answer.
+- `internal/router/habit.go` — `ParseHabitQuery`, which requires a habit marker
+  ("обычно", "каждую", "привычки", …) and parses the weekday deterministically.
+- `cmd/mavend/actions_query.go` — a `habits` query source, so "что я обычно делаю
+  по вторникам?" is answered.
+
+**Not shipped, and not to be shipped as written:**
+
+- *Step 3, LLM-generated profile stored as a fact.* The profile is COUNTED, not
+  generated. A 1.7B asked to summarise a year of habits produces fluent claims
+  about the owner's life that no row supports, and a wrong claim about him is the
+  most expensive kind of wrong maven can be. Counting is verifiable and cheap.
+- *Step 5, incremental updates on fact write.* There is no cache to keep fresh —
+  the profile is recomputed on the question, so a new fact is already in the next
+  answer. A cached profile that can disagree with its own rows is two truths.
+- *Step 4, proactive daily plan proposals via the dispatcher.* Maven is not a nag,
+  and a nudge at 08:00 every day proposing the day is the definition of one. The
+  sanctioned path from "she noticed a pattern" to "she acts on it" already exists:
+  `internal/pattern/detector.go` proposes a routine, and the owner accepts it on
+  `/routines`. It goes through him.
+
+Still open, if wanted later: `MethodGetBehaviorProfile` + a `/dash` panel (step 7).
+The counted profile needs no new IPC method to be *asked* about — the query source
+reads `RecentFacts` over the existing surface — so this is a display concern only.

+//
+// The profile is COUNTED, not generated. docs/plans/09-behavioral-memory.md
+// asks for an LLM to write a behaviour profile daily and store it as a fact;
+// this does not do that, on purpose. A 1.7B asked to summarise a year of habits
+// will produce fluent claims about the owner's life that no row in the store
+// supports, and a wrong claim about him is the most expensive kind of wrong
+// maven can be. Counting distinct days per weekday is verifiable, cheap enough
+// to run on the question, and cannot invent a habit he does not have.
+//
+// Recomputed on read rather than cached as a fact for the same reason the store
+// is append-only: a cached profile can disagree with the rows it came from, and
+// then there are two truths. The plan's step 5 ("profile updates on fact write")
+// exists to keep a cache fresh; there is no cache, so a new fact is already in
+// the next answer.
+//
+// It is also read-only and unprompted-free. The plan's step 4 — a morning
+// dispatcher nudge proposing the day — is deliberately NOT here: maven is not a
+// nag, and proposing plans at 08:00 every day is the definition of one. Pattern
+// inference that leads to a routine the owner accepts already exists in
