- Around line 278-303: Track a run generation in the `odinWasm.run` flow and
pass it through `runOnPage` to `runModuleOnPage`; increment it for every run,
and have each `requestAnimationFrame` callback return without stepping or
scheduling another frame when its generation is stale. This must stop an earlier
`js_wasm32` loop after any subsequent run, including a WASI run.

| `args` is passed to the program as its command-line arguments, `compileArgs` is added to the `odin build` command line, and `target` selects the target the program is built for (`wasi_wasm32`, the default, which runs on a WASI host, or `js_wasm32`, which runs on the browser's JavaScript runtime). |

Limit the args claim to the WASI target.
When a user selects js_wasm32, the page-run path does not pass args to the program. The worker-run path passes args only when it runs a WASI program. State this target restriction here, or pass the arguments through the page runtime. (raw.githubusercontent.com)

| - The `vendor` collection is not shipped: a program that imports a `vendor:` package will not find it. | ||
| - No threads, files, sockets or subprocesses: WASI preview 1 has none, and a program is given an empty filesystem. | ||
| - A program that never returns blocks the tab; both targets run synchronously. |

Distinguish a blocked worker from a blocked tab.
If a wasi_wasm32 program never returns, it occupies the worker. It does not block the page's main thread. A non-returning js_wasm32 program can block the tab. State the limitation separately for each target. (raw.githubusercontent.com)

Stop the previous animation loop on every Odin run.
runModuleOnPage starts a requestAnimationFrame loop for js_wasm32 modules that export step. A later run does not invalidate that loop. Each later js_wasm32 run can add another loop, and even a later WASI run leaves the existing page loop active.
The starter button uses the default wasi_wasm32 target, so it does not exercise this page-step path unless custom settings select js_wasm32.

Important
test:i18n-export fails on this PR — the committed language-info.lokalise.json notes for the Odin section do not match what the export tooling regenerates from language-info.html. I reproduced it locally (npm run test:i18n-export → "File contents do not match for language-info.lokalise.json"). Fix before merge; details inline.

Reviewed changes
Re-reviewed the PR after the latest push. The only change since the prior pullfrog review is a Crystal toolchain upgrade; the earlier review's findings were verified addressed and their threads retired.
- Upgraded the bundled Crystal compiler to
@live-codes/crystal-wasm@0.3.0(from0.2.0) and updated the Crystal docs version note toCrystal v1.22.0, dropping the now-obsolete "1.17.0 only" limitation. The package still shipsdist/crystal-wasm.global.js(globalcrystalWasm) and theassets/crystal/layout, andcreateCompiler/runreturn the same{ output, errors, exitCode }shape the worker expects, so the glue needs no changes.
Verified locally: npm run test:i18n-export → "All files match.", npx jest src/livecodes/languages/odin-wasm 5/5, npm run typecheck:app clean.
