Dependencies and toolchain

• Updated quiche from 0.29.1 to 0.29.2: corrects stream send-buffer accounting so the congestion controller's app-limited detection and Stats::tx_buffered_state track the bytes actually buffered. (The release also fixes use-after-frees in quiche's C FFI API, which this package does not use — it links the Rust API with the ffi feature disabled.)
• Updated napi from 3.9.0 to 3.9.4 and napi-derive from 3.5.6 to 3.5.7: ThreadsafeFunction weak-reference flag sync, Reference finalize-callback Arc/Rc unification, and zero-copy external strings — all on FFI paths this package exercises (TSFN event delivery and recyclable external buffers).
• Refreshed the compatible Rust dependency graph, including bytes 1.12.0, io-uring 0.7.13, log 0.4.33, and env_logger 0.11.11.
• Updated build/dev tooling: @napi-rs/cli to 3.7.2 (regenerates the native loader with corrected tri-state NAPI_RS_FORCE_WASI handling), @types/node to ^26 (aligning the type baseline with the Node 26 runtime), eslint to 10.6.0, typescript-eslint to 8.62.1, and playwright to 1.61.1.

Testing

• Fixed the browser HTTP/3 e2e Chromium case on Linux. Chromium's certificate verifier on Linux reads the per-user NSS database (~/.pki/nssdb), not the launch-profile NSS db, so the prior profile-only CA import left Chromium's forced-QUIC handshake failing with CERTIFICATE_VERIFY_FAILED. The test now also imports the CA into the user NSS database (with matching teardown), so Chromium completes the HTTP/3 handshake on Linux.
