HTTP2 memory fix, stream backpressure tweak

HTTP/2 now keeps header blocks charged while streams live (ba82a41)

maxSessionMemory now continues counting header blocks after they’re handed to JS, instead of dropping the charge too early. That closes a regression where stalled streams could keep memory alive without it being reflected in session accounting, and the docs/tests were updated to match.

pipeToSync() no longer counts rejected writes as accepted bytes (696030d)

The sync stream pipeline now distinguishes between a real accepted backpressure signal and writeSync()/writevSync() returning false without taking ownership of the data. This fixes byte accounting in pipeToSync() and prevents it from over-reporting progress for writers that reject a chunk.

test_runner watch mode handles cwd with isolation disabled correctly (45c7071)

When spawning the watch child with isolation: 'none', the runner now passes the current test files or glob patterns instead of reusing the parent process argv. That keeps discovery scoped to the configured working directory and avoids rerunning the wrong entrypoint.
