sdk: release 0.2.23

[foxnne]

What changes

sdk_version goes from 0.2.22 to 0.2.23. Merging tags sdk-v0.2.23, publishes its tarball, and asks the store plugins to repin.

Why now. The plugin boundary's fingerprint moved since sdk-v0.2.22 (0x1bf417f6… → 0x65096e94…, by #360), so store plugins built against 0.2.22 don't load in a fizzy built from main, and fizzyed.it/app is built from main. Also, #355 moved the plugins service to version 2, and the agent plugin's fizzy_build asks for version 1 until it repins.

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

The sdk PRs since sdk-v0.2.22:

• sdk: a plugin's panic message reaches its crash report #360: a plugin's panic message reaches its crash report. This moves the fingerprint.

Additive, reaching plugins with this release:

• sdk: the plugins service says who each plugin is and what it registered #355: the plugins service is version 2, with list (each plugin's identity, link, version, registration counts and status). A caller built for version 1 is refused until it rebuilds, which this release's repin does.
• app: a crash report says whose code crashed #351: a crash report says whose code crashed (sdk/plugin_sdk.zig).

Also reaching plugins (core/):

• core.viz, graphics for live numbers: line, bar, stat, Table (core: core.viz, graphics for live numbers; the profiler draws with them #345); Pie, keyColor, palette (core: viz.Pie; the profiler shows where a frame went as a pie #347); the table's rounded header and shaded rows (core: viz tables have a rounded header and shaded rows, no border #359).
• core.profile:
  • lookback(): 30 s of costs and the frames over budget, plus ReportOptions.over_ms / .hitches and selfTimes (core: the profiler keeps 30 s of costs and the frames over budget #353).
  • frameCauses() and ReportOptions.causes: why each frame happened (core: the profiler says why each frame happened #364).
  • phase / Phases / ReportOptions.startup: startup timing (app: fizzy times its own startup, and a handover's #365, which landed inside core: the profiler says why each frame happened #364's squash commit).
  • The profiler's abi stays 4.

Verified

• macOS:
  • zig build and test-sdk-version on this head.
  • scripts/pack-sdk.sh packs fizzy-sdk-v0.2.23.tar.gz.
  • Every store plugin (fresh pulls of pixi, zig, drive, atlas and ghostty main) builds against this tree's sdk/ with zig build --fork=<sdk> into a throwaway profile (31/31, and 28/28 for each of the other four). The fingerprint moved, so each repin PR is a real rebuild, but none should open as a draft for a broken build. The agent and chat plugins build too (22/22, 19/19).
• Windows:
• Linux: CI.
• Web:

Follow-ups

• Each repin PR merged and its plugin tagged (the plugin repos' tags stay the maintainer's).
• fizzyedit/agent and fizzyedit/chat repin to the sdk-v0.2.23 tarball.
