update d.ts and .js files (generated JS pipeline)

[summeroff]

Description

Make js/module.ts the single source of truth and treat the shipped JS surface as generated tsc output:

• js/module.{js,d.ts} and the index.* / type_check.* siblings are tsc outputs of js/tsconfig.json. The npm package ships them as-is, so they stay committed, but they must match tsc output.
• yarn build:javascript regenerates them; yarn local:build chains it.
• New CI workflow .github/workflows/check-js-generated.yml (via ci/check-js-generated.sh) regenerates and fails the build if any committed js/ output is stale.
• tsconfig.json: target es6 → es2020, drop the deprecated suppressImplicitAnyIndexErrors.
• Regenerating surfaced and fixed real drift between module.ts and the committed declarations (removed dead IDisplay/startup/shutdown, added copyFilters/getMediaState/getItemsInRange/active, removed a duplicate setFilterOrder, etc.).

Enums are intentionally left as const enum — converting them to regular enums puts their runtime objects in module.js and breaks consumers (e.g. desktop) that import enum values and rely on const-enum inlining to keep osn out of their bundle.

Motivation and Context

The committed js/ outputs were hand-maintained and had drifted from module.ts. This removes the manual step (generate + CI-enforce) and corrects the drifted declarations.

How Has This Been Tested?

• yarn build:javascript — clean compile (tsc exit 0).
• ci/check-js-generated.sh reports a clean tree after regeneration.

Types of changes

• Tweak (non-breaking change to improve existing functionality)

Checklist:

• The code has been tested.
• All commit messages are properly formatted and commits squashed where appropriate.
• I have included updates to all appropriate documentation.

Pull request overview

Treats js/module.{js,d.ts} and siblings as tsc outputs of js/module.ts, regenerates them to remove drift, and adds CI enforcement that the committed outputs stay in sync. Also bumps the tsc target to es2020 and drops the deprecated suppressImplicitAnyIndexErrors. One unrelated C++ change removes an audioEncoder InstanceAccessor.

Changes:

• Regenerated js/module.js, js/module.d.ts, and js/type_check.js; aligned declarations with module.ts (added copyFilters/getMediaState/getItemsInRange/active/previous/is_first/is_last/last, removed dead IDisplay/startup/shutdown/initialized/version/duplicate setFilterOrder, switched IModule to readonly fields, etc.).
• Added ci/check-js-generated.sh plus .github/workflows/check-js-generated.yml to regenerate and fail on stale committed outputs; local:build now chains build:javascript; README documents the workflow; tsconfig.json updated (target es2020, drop suppressImplicitAnyIndexErrors).
• Removed the audioEncoder InstanceAccessor from EnhancedBroadcastingSimpleStreaming (unrelated to PR purpose).

This is a false positive: audioEncoder is still registered on EnhancedBroadcastingSimpleStreaming — staging declared the same InstanceAccessor("audioEncoder", ...) twice (this Init block had it at both the videoEncoder-adjacent line and again after enableTwitchVOD). This hunk removes only the duplicate second registration; the first remains, so stream.audioEncoder get/set still work and the referenced tests are unaffected. Net effect is a no-op de-duplication.
