chore(deps): upgrade to TypeScript 5.9.3 and jest 29

gnbm · gnbm · commit eeeb88936c14 · 2026-06-15T15:29:05.000+01:00
Upgrade the TypeScript toolchain across all packages:

- typescript    ~4.8.0  -&gt; ~5.9.3
- ts-jest       ~26.3.0 -&gt; ^29.4.11
- jest/jest-cli ^26.x   -&gt; ^29.7.0  (stays on 29 to keep Node 16 support)
- @types/jest   ^26.x   -&gt; ^29.5.14
- @types/node   ~16.0.0 -&gt; ^16.18.126 (16.0.3 conflicted with TS 5.9 libs)
- tslib         ^2.0.1  -&gt; ^2.8.1

Required code/config changes:
- jest.config.base.js: migrate ts-jest globals -&gt; transform API, tsConfig -&gt; tsconfig, explicit testEnvironment: node
- utils-array reduce(): annotate accumulator T|U + cast awaited result (TS 5.9 Awaited/NonNullable inference)
- tests: drop async from async-done callbacks (utils-fs), convert to async()+expect.assertions (utils-subprocess), spyOn().and.callFake -&gt; jest.spyOn().mockImplementation (utils-network), legacyFakeTimers for timer-mock assertions (cli-framework-output)

Validated: build + lint + full test suite green.
