Fix(typecheck): resolve PR1219 regressions + fix existing main TS errors

[joonsoome]

Issues

1. Regressions introduced by PR #1219 (3 type error for awaiting #1200), and
2. Pre-existing typecheck failures already present on upstream/main (6 issues)
   The branch is rebased on top of upstream/main, and both local checks now pass.

Branch : fix/pr1219-typecheck
Commit : 0c302584 — fix: make typecheck pass

Verification

• pnpm check → 0 errors
• pnpm -s exec tsc -p tsconfig.json --noEmit → exit 0

1) PR kwaroran#1219 regressions fixed (new breakages introduced by the PR)

While reproducing pnpm check on pr-1219, I found 9 errors total:

• 6 already exist on upstream/main (baseline)
• 3 are introduced by PR fix: Hyper Memory V3 'ot' & 'startsWith' error Bug Resolve kwaroran/Risuai#1219 (regressions)
  These PR-specific breakages are now fixed:
• Missing module: src/ts/util/inlayTokens
  • hypav3.ts imported src/ts/util/inlayTokens, but the module did not exist, causing typecheck to fail.
  • Fix : added/implemented the missing module export via inlayTokens.ts and introduced inlayTokenRegex (resolves TS2307).
• New settings keys without Database schema/defaults
  • advancedSettingsData.ts introduced bindKey: 'checkCorruption', but Database had no such field/default.
  • accessibilitySettingsData.ts introduced toggleConfirmRecommendedPreset, also missing from Database.
  • Fix: added both keys to the Database type and ensured defaults are set in database.svelte.ts (setDatabase() defaults to false).

2) Pre-existing upstream/main typecheck failures fixed (not introduced by PR kwaroran#1219)

These issues were already failing on main, and are included here to keep the tree typecheck-clean:

• plugins.svelte.ts
  • Removed window.trustedTypes typing error (with required unknown casting)
  • Removed @ts-expect-error
  • Forced createRealScript() return type to string
• IconButton.svelte
  • Re-destructured id from $props() to remove the id={id} TS error\
• RealmFrame.svelte
  • Reverted asBuffer(...buffer) back to the #1200 approach using toArrayBuffer(Uint8Array) to fix ArrayBuffer typing mismatch
• hypav3.ts
  • Kept sanitization behavior: replace {{inlay...}} tokens with [Image] in summaries

Note: postcss-selector-parser TS2307

The postcss-selector-parser TS2307 was caused by an out-of-date local node_modules.
After running pnpm install --frozen-lockfile, the correct install/linking resolved it (no shim files added).
