build: prepare v1.1.0 release (#145)

[aksOps]

The release slice of map #136: places the one spinner the restyle cut left
unassigned, then carries the v1.1.0 notes.

Closes #145.

The leftover spinner

Spec section 5.2 assigns the bubbles/v2 spinner to every ...ing... busy
state that was static text. PR #150 wired it into the ADR split and the issue
import and recorded one exception (deviation 8): the card editor's drafting
and saving states were #143's surface, already shipped before the pattern
existed, and were left for the map to place. This places them.

The pattern is #150's, copied whole:

• cardeditor.Model holds a spinner.Model, constructed from the theme's
  Spinner token and re-adopted in SetStyles, so the editor never picks its
  own frames.
• busy() is drafting || saving; spinTick drops the tick the moment
  neither is in flight, so an idle editor costs no timers.
• The tick is batched at the operation start (startDraft, both branches
  of startSave), not armed for as long as the overlay is open.
• busyPrefix() strips the frame to plain text so the footer band renders it
  in the band's own tier, and returns empty for a zero-value model.
• spinner.TickMsg joins cardeditor.IsMessage, so the root routes it.

Tests

TestSpinnerAdvancesOnlyWhileDraftingOrSaving mirrors the existing
adrsplit and issueimport spinner tests: idle drops the tick, both busy
states take it, both footers carry the frame, a settled editor does not re-arm,
a zero-value model renders no frame, and the root routes the tick.

Three test helpers now walk a batch and skip the spinner tick, which is what
#150's deviation 7 predicted: commandMsgForEditor in the editor package and
resultSkippingSpinnerTick in the root package.

No golden changed: the drafting and saving footers are not in any pinned frame.

Release notes

docs/releases/v1.1.0.md, in the v1.0.1 format. v1.1.0 is a minor: the UI
changed materially and nothing broke. The notes cover the Strata design
language, the full-frame board and proportional overlays, the visible
semantic-colored buttons, the adopted charm components, the huh v2 dialog
fields, the Home/End fix including the untypeable h/l import bug, Ctrl+A
select-all, and the theme package with zero styling outside it. Upgrade
section records no database migration; install and verify are as before.

.gitignore gains the notes file: /docs/releases/* is ignored with a
per-release allowlist.
