release: cut v2.1.9 "Fathom" (presentation and signal — "Aperture")#294
Conversation
Cuts the v2.1.9 release — the presentation-and-signal step of the v2.1.5 → v2.2.0 "deepen the existing project" run, a marquee display release. Bumps the workspace version 2.1.8 → 2.1.9, renames CHANGELOG `[Unreleased]` → `[2.1.9]`, refreshes Cargo.lock, syncs the README badge / current-release paragraph / BibTeX, and authors `.github/release-notes/v2.1.9.md`. v2.1.9 (PR #283) is all opt-in / default-off display work, so the shipped default presentation stays byte-identical (AccuracyCoin 141/141, nestest 0-diff, visual_regression byte-identical): - Marquee CRT shader stack: WGSL ports of CRT-Royale, crt-guest-advanced, and Sony Megatron (HDR), selectable with mask/scanline/curvature controls + per-game presets. - Raw NTSC composite signal-decode path: a new rustynes-ppu::raw_signal un-decoded 2C02 composite model + a signal_decode.wgsl demodulator (rotating oscillator, edge-consistent phase) for artifact-accurate color. - GIF + WAV capture (extending av-record) + a generated-NTSC palette editor with a live preview. No default-build behavior change. Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>

Code Review
This pull request prepares the project for the v2.1.9 'Fathom' ('Aperture') release. It updates the workspace package version from 2.1.8 to 2.1.9 across Cargo.toml, Cargo.lock, and README.md, adds the corresponding release notes and CHANGELOG entry, and updates the README documentation to describe the new marquee CRT shader stack, raw NTSC composite signal-decode path, GIF/WAV capture, and generated-NTSC palette editor. There are no review comments, so I have no feedback to provide.
Important
