…ripherals + quality/security) The milestone cut that closes the v2.1.5 -> v2.2.0 "deepen the existing project" run, landing its two remaining marquees plus a peripherals and quality/security pass. Every change already merged (PRs #290, #291) is additive or default-off; the deterministic core is untouched, so this cut itself moves only version strings + release docs and no framebuffer/audio byte. Marquees (already on main via #290/#291): - Netplay matchmaking + lobby (B5) — a browse-and-join room directory (`ListRooms`/`RoomList`) and server-side quick-play (`QuickMatch`/`Matched`) over the existing room-code / TURN transport, delayed-stream spectators (`SpectatorConfig.delay_frames`, reveal-horizon gated), a graded hysteresis desync verdict (`DesyncStatus`, threshold 3 ~= 1.5 s), and graded multi-second peer-liveness RTT timeouts (`PeerLink` + `DisconnectReason::PeerTimeout`). Signaling and telemetry only — the rollback/determinism contract is untouched. - FDS medium model completion (F4.3) — per-block CRC-16/KERMIT re-emitted on every BIOS write (`resynth_block_crc`) over a synthesized gap/mark wire image, an opt-in default-OFF continuous analog head-seek / velocity model (`Fds::set_analog_head_seek`) replacing the flat `HEAD_RESEEK_CYCLES` window, and a BIOS-free synthetic write-verify oracle (`Fds::medium_write_verify`) as the CI-verifiable half (the real-BIOS write-CRC path stays gitignored/local — copyright disksys.rom). Additive v4 FDS save-state tail; with the model off a non-writing `.fds` run is byte-identical to prior releases. Peripherals (#291): the Famicom `$4016`-bit-2 microphone (`Nes::set_microphone`, `$4016`-only, never `$4017`) and a 3x3-aperture Zapper light-timing model (`ZAPPER_APERTURE_*`), both additive/default-off. Quality/security (#290): cargo-fuzz targets grown 3 -> 8 (`ppu_reg_io`, `apu_reg_io`, the high-value `netplay_message`, `save_state`, `movie`), which surfaced and fixed two real OOM-DoS paths in `Movie::deserialize` (untrusted `frame_count` -> unbounded `Vec::with_capacity`, and a zero-`bytes_per_frame` infinite push loop) byte-identically for valid input; a read-only Tools -> ROM Info browser (dump-identity CRC32 keys + SHA-256 + per-game DB entry + decoded header, `&Nes`, never mutates); and four new MkDocs handbook pages. Cut mechanics: `[workspace.package] version` 2.1.10 -> 2.2.0 (Cargo.lock refreshed across all 18 workspace crates), CHANGELOG `[Unreleased]` renamed to `[2.2.0]` with a fresh empty `[Unreleased]`, `.github/release-notes/ v2.2.0.md` authored, and README badge / BibTeX / current-release paragraph updated. `release-auto.yml` tags + publishes on main going green. Sacred gate (verified on the merged #290+#291 tree): AccuracyCoin 141/141 (100.00%), nestest 0-diff, `pal_apu_tests` 10/10, `visual_regression` byte-identical, netplay rollback-determinism + snapshot-restore-replay + FDS synthetic write-verify green, `no_std` thumbv7em cross-compile, full host fmt/clippy/rustdoc/markdownlint, version consistency.

Code Review
This pull request prepares the repository for the v2.2.0 'Capstone' release. It updates the version numbers across Cargo.toml, Cargo.lock, and README.md, adds a comprehensive release notes document under .github/release-notes/v2.2.0.md, and updates the CHANGELOG.md with the details of the new release. There are no review comments provided, so I have no feedback to address.

Version bump + release docs only — all code already merged via #290 (netplay lobby / spectators / desync-liveness hardening + fuzz 3→8 + ROM Info browser + handbook) and #291 (FDS medium model + Famicom mic + Zapper aperture).
