Replace all MCP Agent Mail references with Liquid Mail in AGENTS.md and
CLAUDE.md. The old system used file reservations and MCP-based messaging
with inbox/outbox/thread semantics. Liquid Mail provides a simpler
post-based shared log with topic-scoped messages, decision conflict
detection, and polling via the liquid-mail CLI.
Key changes:
- Remove entire MCP Agent Mail section (identity registration, file
reservations, macros vs granular tools, common pitfalls)
- Update Beads integration workflow to reference Liquid Mail: replace
reservation + announce patterns with post-based progress logging and
decision-first workflows
- Update bv scope boundary note to reference Liquid Mail
- Append full Liquid Mail integration block to CLAUDE.md: conventions,
typical flow, decision conflicts, posting format, topic rules, context
refresh, live updates, mapping cheat-sheet, quick reference
- Add .liquid-mail.toml project configuration (Honcho backend)
