feat: unified messaging TUI MVP — Synapse + 7 mautrix bridges + Textual TUI + MCP draft staging

One-command local stack: cp .env.example .env && make up. Idempotent
bootstrap renders Synapse + bridge configs from pristine upstream examples,
provisions databases, registrations, double puppeting, and the admin user.
Textual TUI with bridge manager, in-terminal QR login, and drafts panel.
MCP server exposes read tools and a human-gated draft send workflow.
