Migrate to Jest 30

[Copilot]

Completes the jest 30 upgrade started in #161. Jest 30 removed several deprecated matcher aliases and improved branch coverage detection, requiring both API updates and new test cases.

Dependency updates

• jest, @types/jest, jest-mock: ^29 → ^30
• ts-jest unchanged (29.x already declares jest 30 peer support)

Removed deprecated matcher aliases

Jest 30 dropped aliases that were deprecated in jest 27+:

// Before
.toThrowError(/pattern/)
expect(fn).toBeCalledTimes(1)

// After
.toThrow(/pattern/)
expect(fn).toHaveBeenCalledTimes(1)

81 toThrowError → toThrow replacements across 9 test files; 4 toBeCalledTimes → toHaveBeenCalledTimes in ComponentsManagerBuilder-test.ts.

New tests for previously-uncounted branches

Jest 30's coverage engine detects branches that jest 29 missed, causing the 100% branch threshold to fail:

• ModuleStateBuilder.warn() — the if (this.logger) false-branch was never exercised because no existing test triggered a warn() call without a logger set. Added a buildComponentContexts test with incompatible major versions and no logger.
• OverrideMapEntry.findProperties() — the if (collectEntries.list) false-branch (direct resource, not an RDF list) was never hit. Added a test that replaces the component's collectEntries property with a bare NamedNode resource.
