Shkarko CodeWhale 0.8.57

Added
- Turns now survive system sleep. When the host suspends mid-stream, the connection used to die on wake with Stream read error: error decoding response body and the turn was lost (#2990). The engine now stamps stream progress with both monotonic and wall-clock time; a large divergence on a stream error identifies a sleep/wake cycle, and the request is silently re-issued (up to the existing 3-retry budget) instead of failing the turn.
- One-command release prep. ./scripts/release/prepare-release.sh X.Y.Z bumps the workspace version, every internal crate dependency pin, the npm wrapper, and the README install-tag examples, refreshes Cargo.lock, regenerates the embedded TUI changelog slice and web facts, and runs check-versions.sh — the v0.8.56 release needed nine follow-up commits for exactly these sync points.
- .github/CODEOWNERS and .github/dependabot.yml (weekly cargo + github-actions updates, monthly npm for web/).
Changed
- The changelog went on a diet. Root CHANGELOG.md now carries recent releases (v0.8.40+); older entries moved to docs/CHANGELOG_ARCHIVE.md. crates/tui/CHANGELOG.md — embedded into every binary for /change — is a generated 15-release slice (scripts/sync-changelog.sh), no longer a 357 KB manual byte-for-byte copy (~300 KB smaller binaries).
- GitHub Release bodies are generated from the tagged version's changelog section (scripts/release/generate-release-body.sh) instead of a hardcoded workflow blob with a hand-pasted contributor list.
- check-versions.sh now also gates web/lib/facts.generated.ts and the README install-tag examples; the CNB mirror pipeline validates the pushed tag against Cargo.toml before generating release notes.
- Docs reorganized: internal design notes moved under docs/rfcs/; stale internal docs (old audits, handoffs, region-specific VM notes) removed.
- Agent-facing polish: the system prompt environment block reports codewhale_version (was deepseek_version), the legacy .deepseek/instructions.md path is no longer advertised in the prompt (still honored for back-compat), and oversized instruction files are truncated with an explicit […truncated: N bytes omitted] marker instead of a bare ellipsis.
Fixed
- Docker images build again. The release docker job failed for v0.8.56 because the Dockerfile still copied the pre-rebrand deepseek / deepseek-tui binaries; they are now symlinks to the codewhale binaries inside the image, so legacy container entrypoints keep working.
- .devcontainer/devcontainer.json used the pre-rebrand container name, mount path, and deepseek remote user.
- Stale --bin deepseek examples, DeepSeek-TUI strings in /change output, and pre-rebrand doc comments.
Removed
- Unused dependencies: tracing-appender and zeroize (TUI crate), rustls (release crate); the orphaned vendor/schemaui-0.12.0 lockfile leftover and a machine-specific one-off scripts/verify_task.sh.
