* docs(coverage): record why two-core Tier A runs stay serial
Answers two review notes on the concurrent Tier A runner with measurements
instead of code changes:
- Two cores stay serial. Two in flight would give each project one Jest
worker, which runs Jest in-band; on a 2-core / 7 GB container ui-playback
and web ran out of their 2 GiB default heap. With a 4 GiB heap it passed
about 15% faster on a warm cache for 1.2 GiB more peak memory. CI runs on
4 cores. A test pins that the defaults never drop to one worker.
- Per-project output buffering is bounded in practice: a big project with
every test failing printed 1.8 MB while its Jest process peaked at 850 MB.

* docs(coverage): say two-core runs keep two workers per project

Tier A coverage runs projects a few at a time (largest first, bounded Jest workers, buffered output, fail-fast kept) and ts-jest transpiles with isolatedModules instead of type-checking per process; five type re-exports become export type, two decorated inputs use import type. Unit Tests and Typechecks job: 26 min -> 9 min (Tier A step 23 min -> 6.5 min).

Adds contract-focused regression coverage for the Electron HTTP server,
remote-control events, settings events, and managed download paths, and makes
Tier A coverage fail closed when instrumentation fails or a runtime-owning
production file disappears from a project or from the merged Istanbul report.
The old `coverage:ci` exited 0 despite a `Failed to collect coverage`
diagnostic: libs/m3u-state/src/lib/effects.ts was simply absent from the merged
map. All 30 Tier A reports are now required, the merged map covers 710 files,
and effects.ts is reported as 0/159 instead of silently disappearing.
Also fixes remote static-file path containment for encoded, malformed, NUL,
POSIX and Win32-style traversal inputs, with behavior-preserving testability
seams.
Statements 69.27% -> 69.54%; http-server.ts 0% -> 90.21%,
remote-control.events.ts 0% -> 96.55%, settings.events.ts 59.25% -> 96.29%.
