Orkuncakilkaya fb728bbefe chore(repo): DX cleanup — categorise examples, text-diffable golden, build/ output (#27 #28 #30)
Repository-cleanup / DX pass folding three tracker items into one coherent
change, verified green end to end (`bin/x test` 49/0, `bin/x selfhost-test`
29/0, `bin/x test-tools` 29/0).

#28 — curate & categorise examples/
- 42 flat entries regrouped into intent-revealing subdirs: games/, rendering/,
  ecs/, events/, networking/, lang/, library/ (was lib/).
- chronorift dir-vs-file duplication resolved: the entry file and its import
  modules now live together under games/chronorift(.ludic).
- Every path reference updated repo-wide (test runner, editor-tool drivers,
  docs/site, design docs).
- New examples/README.md indexes the whole set with run commands.
- Showcase examples without a self-asserting entry (hello, events, net_rt) now
  get a compile-only rot guard in `bin/x test`, so nothing here rots silently.

#30 — text-diffable golden baseline
- The 4 binary selfhost/golden/*.ppm blobs are replaced by a single
  selfhost/golden/renders.sha256 manifest (SHA-256 per render). Hashes are
  byte-identical to the old PPMs, so the baseline is unchanged — only its form.
- game_case now compares framebuffer hashes; a regression shows as a changed
  hex line in review, not "binary files differ".
- New `bin/x golden` regenerates the manifest deliberately (review with
  `git diff selfhost/golden/renders.sha256`).

#27 — PPM & asset handling
- Headless renders now write build/out.ppm, never the repo root; `x app`,
  `x clean`, messaging and .gitignore updated to match. Nothing is written to
  the working root any more.
- Redundant local Kenney .zip archives removed (the art ships extracted;
  .gitignore already excludes *.zip). CC0 License.txt files retained.

# program_events.ludic — EV1 for the program ("game") scope: @Public on @OnStart
# and @OnQuit promotes them to program_start / program_quit events, so a mod runs
# its own setup after the game boots and its own teardown as the game exits — the
# top-level modding entry points (Blender's app handlers, Minetest's on_shutdown).
#
# Running it prints: 1 100 2 200
program ProgramEvents {
property Health { hp: int = 0 }
model Dummy { Health }
@Public @OnStart handler Boot { print(1) } # -> program_start
@Public @OnQuit handler Bye { print(2) } # -> program_quit
@On(program_start) handler ModInit { print(100) } # mod boots after the game
@On(program_quit) handler ModDone { print(200) } # mod tears down as the game exits
handler Run phase Update { quit() }
}
