- Bump workspace version 0.8.22 → 0.8.23 across Cargo.toml, every per-crate path-dependency pin, npm/deepseek-tui/package.json (both `version` and `deepseekBinaryVersion`), and Cargo.lock. - Add a 0.8.23 CHANGELOG entry covering the security hardening stack (sanitized child env, plan-mode tool surface, sub-agent approvals, symlink walks, runtime API auth, shell safety classification, MCP config path traversal), the macOS Keychain prompt fix, the #1244 MCP spawn error visibility + env passthrough work, the compact-thinking UX change, and a Known issues callout for mid-run MCP stderr. - Backfill missing CHANGELOG entries for v0.8.21 (community-heavy release, contributors credited) and v0.8.22 (fetch_url redirect validation). The gap was unintentional, so contributor work is being reflected in-repo now. - Add docs/RELEASE_CHECKLIST.md so future releases gate on the CHANGELOG/version/preflight steps explicitly.
