hcom v0.7.21

• GitHub Copilot CLI support — added support for the Copilot CLI.

• Kimi Code CLI support (#59 by @ekhodzitsky) — added support for Kimi Code CLI.

• Pi Coding Agent support — added support for Pi Coding Agent.

• OpenCode model variants (#61 by @azkore) — preserves reasoning effort model variants for OpenCode-delivered messages and supports passing the variant via launch arguments.

• Regime-aware environment resolution — nested agent launches now resolve env variables from the user's login shell instead of starting with empty env or inheriting polluted environment states from parent agents.

• Workspace Auto-Trust — config option to automatically grant workspace trust for Gemini, Codex, Copilot, and Cursor on launch to prevent headless execution from hanging on first-run gates.

• Diagnostics — hcom list <name> now shows detailed status, uptime, parent/child hierarchy, active communication bindings.

• TUI fixes - The TUI footer now displays better dynamic, context-aware key hints, and remote agent display names no longer double-namespace (#63).

• Launcher, safety, and PTY fixes:

  • resume and fork commands under AI tools now block briefly to report status exit codes
  • guards AI tools from accidentally broadcasting to >3 agents without --go
  • fixes fork argument mapping
  • resolves sandbox termination errors after pane close
  • ensures resumed canonical agents remain killable (#62 by @mmkzer0).
