Support current Codex selector bundles

[ericskavinski]

Summary

• discover hashed model-selector and React DOM assets instead of hardcoding filenames
• add complete compatibility profiles for legacy bundles and Codex 26.707
• map current icon, hook, predicate, and slider symbols safely and reject unknown or ambiguous bundles
• fix the Windows PowerShell 5 default destination calculation
• document post-update React error 130 troubleshooting

Root cause

Codex Desktop 26.707 changed both hashed asset filenames and minified identifiers. The old patch rendered Qe/tt (now JSX runtime objects) as icons and ye (now a lazy-loader cache object) as the slider, producing React error 130. The current renderable symbols are $e/nt and be.

Verification

• npm run check (6 tests)
• git diff --check
• successful portable build from installed Codex 26.707.6957.0 app.asar
• fresh application startup without React/error-boundary breadcrumbs
