v0.3.0 — chunked materialize for huge forks

The fix

Forking a huge session (60万+ events) crashed or OOM'd because encodeMaterialization → eventLines = map(JSON.stringify).join() builds a single ~501MB string; 74万 events throws RangeError: Invalid string length (V8 ~512MB cap).

v0.3.0 patches JsonlSessionPersistence.encodeMaterialization (rc.6 signature-guarded) to emit one zstd frame per 50k events. Multi-frame output is natively decoded by dsh's scanZstdFrames, byte-compatible.

	heap peak	74万 events
before	1572MB	RangeError
after	1155MB	safe

Why 'single session fine, fork breaks'

• normal sessions persist incrementally (appendLines, small batches)
• fork children persist via materialize (full seed) — the only path that serializes the whole log at once
