Krzysztof kuhy Rudnicki a874e09b65 Cut the llm-design-spec template from 12 sections to 7
Audited the template against 514 real Claude sessions (1503 top-level
prompts) joined to the 49 notes in BACKLOG.md. Sections were judged on
whether the agent actually read them, not on fill rate — four of them
said "leave blank if none" in their own helper, so a low fill rate was
the section working correctly.

Measured over the 22 note/session pairs:
  estimate  filled 22, referenced  1 (4%)
  done      filled 22, quoted back 4 (18%)
  refs      filled 14, URLs fetched 5 (35%)
  tech      the agent opened pubspec.yaml/CLAUDE.md anyway in 54%
  ask       100% ask rate with it, 92% without — no measurable effect

Kept: title, what, where, must, done. Dropped: tech (into `where`),
ask, nice and never (into `must` as `optional:` / `must not:` lines),
depends, estimate. Renamed `refs` -> `read first`. Added `verify`, the
only addition: "test it yourself, on the phone" was the single most
repeated correction in the corpus, and 3 of the 7 filled `never`
sections were already smuggling it in.

Fixes a latent data-loss bug found while testing this. parse() treats
an unknown `## heading` as content on purpose (values may contain
subheadings), so a legacy `## tech` block was folded into the preceding
section's value AND the note still reported conforming — opening any
old note in the stepper would have swallowed it on the next save.
NoteTemplate.retiredLabels now makes those notes explicitly
non-conforming, so they open raw and untouched.

tool/migrate_backlog.dart converts an old export (export -> migrate ->
import). It is idempotent and gated: it throws if a rewritten note does
not conform or if any source line vanishes. All 49 notes migrated on
the desktop and merged to the phone (0 new, 25 updated, 24 unchanged).

Also formats the few files dart format had never been run over, and
extracts a local in frame_stats_io.dart so the reflowed line stays
under 80 chars.
