sdk: release 0.2.27

[foxnne]

What changes

sdk_version goes from 0.2.26 to 0.2.27. Merging this tags sdk-v0.2.27 and publishes its tarball.

Why now: the agent plugin's stroke step (fizzyedit/agent#11, on agent main) uses tape.Script.StrokePoint from #431, which no released SDK has, so agent's new CI (fizzyedit/agent#13) can't pass against its pinned SDK until it repins to a release that carries it.

SDK impact

• None
• Core-only or additive: reaches plugins at the next SDK release
• Fingerprint moved: recorded in sdk/src/version.zig, sdk_version untouched, PR labelled sdk
• SDK release: bumps sdk_version, lists the sdk PRs since the last sdk-v* tag

sdk PRs since sdk-v0.2.26:

• sdk: a document's history as a line, and going to a step #434: two optional document vtable members, historyLine (a document's undo history as a line of steps, with a version) and historyGoTo (undo or redo to a step), with Plugin.HistoryLine. An owner without them has no timeline; undo and redo are unchanged. The fingerprint moved, so the repin automation opens a repin PR in each store plugin.

Reaching plugins, no fingerprint move:

• tape: a stroke carries the pointer in straight lines #431: tape: a stroke carries the pointer in straight lines (Script.StrokePoint).
• tape: a caption follows where the pointer reaches, not a pen's path #432: tape: a caption follows where the pointer reaches, not a pen's path.
• replay: a tape's pointer gives way to a cursor the app draws itself #433: replay: a tape's pointer gives way to a cursor the app draws itself.
• core: the bubble spinner keeps its bubbles near one size at any scale #427: core: the bubble spinner keeps its bubbles near one size at any scale.

Open sdk-labelled #437 (the Zig 0.17 switch) is a draft and not in this release.

Verified

• macOS:
  • On this head, zig build test-sdk-version: 12/12 steps succeeded. scripts/pack-sdk.sh packs fizzy-sdk-v0.2.27.tar.gz.
  • fizzyedit/agent (main plus windows: the socket server builds for Windows agent#14) builds against this sdk/ (--fork) for x86_64-windows, x86_64-linux-gnu and aarch64-macos, and zig build test passes.
• Windows:
• Linux: CI.
• Web:

Follow-ups

• The repin automation opens sdk: repin to fizzy SDK 0.2.27 PRs in the store plugins whose build needs it. agent repins too, and then ci: check pull requests with plugin-build-action's check.yml agent#13's CI can go green.
