Leverage TypeScript 5.x features: using, withResolvers, type predicates, template literals, satisfies - #79

…es, template literals, satisfies
- tsconfig: bump lib from ES2022 to ES2024 + ESNext.Disposable, enabling
Symbol.dispose and Promise.withResolvers type definitions
- webcam.ts: add withDispose() helper to adapt .close() APIs to Symbol.dispose;
use `using decoder = withDispose(new ImageDecoder(...))` in getAnimatedWebPInfo
so decoder.close() is guaranteed on early returns and exceptions; add
[Symbol.dispose] to WebcamRecorder as an alias to cleanup(); rewrite
stopRecording() and measureEmpiricalFrameRate() with Promise.withResolvers()
to flatten the guard clauses out of the Promise constructor
- PlottableProperty.ts: export isRecordPlottable / isLivePlottable type-guard
functions with explicit p is T predicates (TS 5.5 can infer these, but
explicit guards also make .filter(isRecordPlottable) produce RecordPlottable[])
- ConfigurableGraph.ts: replace inline "accessor" in x checks with the named
type guards from PlottableProperty
- OverlayToolsModel.ts: add VelocityUnit and AccelerationUnit template literal
types derived from CalibrationUnit; narrow velocityUnitProperty and
accelerationUnitProperty from TReadOnlyProperty<string> to the precise types
- brand.ts: switch from const Brand: TBrand = {} (widens literal types) to
const Brand = {} satisfies TBrand (validates shape while preserving literals)
