Inline debugger values looked up source identifiers in a plain object, so a name like toString on a nearby line resolved to an inherited Object.prototype member and crashed the editor's inline-values plugin. The execution-point subscription lived in that plugin, so after the crash the highlighted line stayed on the old position while the stack had moved on, and resume or stop did not clear it.
Locals are now kept in a prototype-free dictionary and looked up by own property, and the execution point is synced by its own plugin so an inline-value failure can't freeze it; hidden editors resync when remounted. Stepping, resume, run to cursor, reset frame and smart step clear the old execution point as soon as the request is sent, stale stack/locals responses from a previous stop are ignored, and another thread's continued event no longer clears the selected thread's execution point.
Fixes#668
Run oxfmt once over the whole repository (formatting only, no logic changes) and add `pnpm format:check` to the frontend CI job so unformatted code no longer builds up. `.oxfmtrc.json` now skips the generated theme docs, test fixtures and code blocks inside Markdown.
