chore(release): v1.19.0 "Afterburner"

[doublegate]

Summary

• Bumps the workspace root version and every individually-versioned crate's Cargo.toml to
  1.19.0, and regenerates Cargo.lock.
• Renames CHANGELOG.md's [Unreleased] section to the dated [1.19.0] "Afterburner" - 2026-07-15 entry, including a ### Fixed note for the real BOLT-stage bug found and fixed in
  PR feat(perf): v1.19.0 "Afterburner" - PGO/BOLT pipeline #109's review.
• Updates docs/STATUS.md's current-release pointer and running summary paragraph,
  to-dos/ROADMAP.md's RustyNES-parity ladder bullet, and to-dos/VERSION-PLAN.md's v1.19.0
  rung with its **RELEASED 2026-07-15** marker.

This closes out the RustyNES-parity roadmap ladder (v1.5.0 → v1.19.0) per
to-dos/VERSION-PLAN.md.

Test plan

• cargo test --workspace --exclude rustysnes-android — all green after the version bumps
• cargo clippy --workspace --exclude rustysnes-android --all-targets -- -D warnings — clean
• cargo fmt --check — clean

Merging this triggers release-auto.yml's automatic tag/publish for v1.19.0.

Code Review

This pull request bumps the workspace and crate versions to 1.19.0 ("Afterburner") and introduces an optional Profile-Guided Optimization (PGO) and BOLT post-link optimization pipeline for the shipping rustysnes binary. The changes include the addition of the training scripts, CI workflow configurations, and comprehensive updates to the project's documentation, including the changelog, roadmap, status, and version plans. There are no review comments to address, so I have no feedback to provide.
