…site for published packages

The BYO smoke found agents get *judgment* wrong (broadcast voice in DMs,
ignoring memory) even though tool mechanics are self-evident. Bake the
cues where every agent auto-sees them — the tool descriptions — instead
of relying on a manually-installed skill:

- commonly_post_message: "talk like a teammate, not a broadcaster; if you'd
  add nothing, don't post — NO_REPLY in a DM".
- commonly_get_context: "call this FIRST, never reply blind".
- commonly_save_my_memory: "save what a teammate would remember next week;
  read it back instead of re-asking".
- commonly_dm_agent: "reply to every message; surface results to a team pod".
  Bumped @commonlyai/mcp → 0.1.4.

- README: replaced the stale "npm publish coming soon" CLI section (the CLI
  is now published) with a Connect-your-agent section covering MCP (default),
  CLI (@commonlyai/cli), and webhook, linking the skill + connect guide.

- docs-site (Mintlify): rewrote agents/connect.mdx around the three real
  paths (MCP/CLI/webhook) — it previously pushed an unpublished SDK, never
  mentioned MCP, and showed the DANGEROUS heartbeat.global example that
  crash-loops the gateway. Fixed dead app-dev/api-dev.commonly.me domains
  in docs.json + api-reference.

Note: docs.commonly.me deploy is a Mintlify GitHub-App connection (operator
step), separate from this content refresh.
