\`patch-package\` postinstall hook applies three changes to keyborg@2.14.0 covering both the ESM (\`dist/index.js\`) and CJS (\`dist/index.cjs\`) bundles: 1. \`event.details = details\` — drop the \`@deprecated\` alias of \`event.detail\`. Tabster reads \`e.detail\` exclusively (verified across src/State/FocusedElement.ts and the rest of the codebase). 2. \`triggerKeys\` / \`dismissKeys\` props + the supporting \`shouldDismiss\` / \`scheduleDismiss\` / \`dismissTimer\` machinery. Tabster only ever calls \`createKeyborg(getWindow())\` with no props. 3. \`canOverrideNativeFocus\` runtime probe. Replaces the \`_canOverrideNativeFocus\` flag with the implicit-true assumption modern browsers (everything since IE9) already satisfy. The conditional \`details.isFocusedProgrammatically\` write becomes unconditional — semantically identical when override works. Bundle deltas (createTabster default-mode): keyborg slice: 3.71 → 3.12 kB (-590 B, -16%) createTabster: 30.78 → 30.18 kB (-600 B) getModalizer: 38.47 → 37.87 kB (-600 B) getMover: 44.54 → 43.94 kB (-600 B) getCrossOrigin: 89.64 → 89.04 kB (-600 B) allExports: 92.09 → 91.50 kB (-590 B) Tests pass: 3 pre-existing failures, no regressions across default, uncontrolled, and root-dummy-inputs modes. Stop-gap until upstream microsoft/keyborg can release the same trims (the changes belong there, not as a Tabster-side fork). Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>

Summary
Mechanical hygiene with no behavioural change:
declare-ify class fields that are assigned in constructors so TypeScript skips emitting init code for them in the compiled JS.Utils.tsto remove dead helpers and inline tiny one-shot utilities at call sites.webkit/moz/msfullscreen vendor-prefix branches inOutline(all currently-supported browsers expose the standard API).Stack context
Stacked on top of #539. Net new in this PR: the source-file cleanups above.
