03a685d5f6 imessage: restrict permission relay to self-chat only
Permission prompts were being broadcast to all allowlisted contacts plus
every DM resolvable from the SELF address set. Two compounding bugs:

1. SELF was polluted by chat.last_addressed_handle, which on machines
   with SMS history returns short codes, business handles, and other
   contacts' numbers — not just the owner's addresses. One reporter's
   query returned 50 addresses (2 actually theirs) resolving to 148 DM
   chats, all of which received permission prompts.

2. Even with a clean SELF, the handler sent to allowFrom + SELF, so
   every allowlisted contact received the prompt and could reply to
   approve tool execution on the owner's machine.

Fix:
- Build SELF from message.account WHERE is_from_me=1 only
- Send permission prompts to self-chat only, not allowFrom
- Accept permission replies from self-chat only

12e9c01d5f Regenerate imessage bun.lock without artifactory URLs
The lockfile had 94 artifactory.infra.ant.dev URLs baked in from
generation behind a private registry. External users hit 401s on
'bun install' and the server never starts. Regenerated against
registry.npmjs.org to match the .npmrc.

d49d339d1e Show input_preview only for Bash in permission prompts
Write/Edit previews are unbearably long over iMessage. Bash is the
dangerous one where seeing the command matters; everything else gets
tool_name + description only.

bfed4635f5 feat(imessage): port permission-relay + lifecycle fixes from telegram
Brings the imessage channel to parity with recent telegram/discord
hardening:

- Permission-relay capability: declare claude/channel/permission,
  handle inbound permission_request notifications by fanning out to
  allowlisted DM chats + self-chat, intercept "yes/no <id>" replies
  after the gate check and emit structured permission events instead
  of relaying as chat. Groups excluded per single-user-mode policy.
- Global unhandledRejection/uncaughtException handlers so the server
  logs instead of dying silently.
- IMESSAGE_STATE_DIR env override for the state directory.
- .unref() on both setInterval timers so they don't block shutdown.
- stdin EOF / SIGTERM / SIGINT shutdown handler that closes chat.db
  and exits cleanly instead of leaving a zombie poll loop.

Adds zod as a direct dep (already transitively present via the MCP SDK)
for the notification handler schema.

1c95fc662b Add imessage channel plugin
iMessage bridge for Claude Code. Reads ~/Library/Messages/chat.db
directly for history and new-message polling; sends via AppleScript
to Messages.app. macOS only.

Built-in access control: inbound messages are gated by an allowlist
(default: self-chat only), outbound sends are scoped to the same
allowlist. The /imessage:access skill manages allowlists and policy.

Requires Full Disk Access and Automation TCC grants — both prompted
by macOS on first use.

Ships full source — server.ts runs locally via bun, started by the
.mcp.json command.
