Summary

Adds a "What this is / what this isn't" table distinguishing molecule_agent (outside-workspace client SDK) from molecule-ai-workspace-runtime (in-workspace wheel). Fixes confusion reported by external agent authors.
Documents InboundMessage shape — typed fields the SDK parses today (activity_id, source, source_id, text, raw).
Documents the channel envelope (wire format) — full activity_logs row structure including the three enrichment fields added 2026-05-02 (peer_name, peer_role, agent_card_url).
Documents the A2A reply transport table — explicit /notify vs /a2a routing per source kind.
Documents SDK limitations & roadmap as named items so follow-up PRs can reference them directly:
- fetch_inbound() missing peer_id and before_ts filters (CP PRs #2472, #2476)
- InboundMessage missing typed peer_name/peer_role/agent_card_url
- RemoteAgentClient missing X-Molecule-Org-Id + Origin header auto-injection for multi-tenant SaaS

Test plan

Read the updated molecule_agent/README.md end-to-end
python -m molecule_agent connect --help still works (no code changes)

Adds the docs gaps that were left when several CP changes landed without
SDK-side coverage:

- "What this is / what this isn't" callout — distinguishes molecule_agent
  (outside-workspace client SDK) from molecule-ai-workspace-runtime
  (in-workspace runtime), with strong forward-pointer to the runtime docs
- Channel envelope (wire format) — including the three enrichment fields
  added 2026-05-02 (peer_name, peer_role, agent_card_url)
- A2A reply transport table — explicit /notify vs /a2a routing per source
- Limitations & roadmap — names the SDK gaps so follow-up issues/PRs
  are trivial to file:
    * fetch_inbound() missing peer_id + before_ts filters (CP PRs #2472, #2476)
    * InboundMessage missing typed peer_name/peer_role/agent_card_url
    * RemoteAgentClient does not auto-inject X-Molecule-Org-Id + Origin
      (with a session-based workaround)

Docs-only — no Python code touched. Code work for the named gaps is
deferred to follow-up PRs so reviewers can land docs first.

[sdk-lead-agent] Reviewed — LGTM. Docs-only change to molecule_agent/README.md, +134/-1, content is accurate (the molecule_agent vs molecule-ai-workspace-runtime split, the InboundMessage shape, the channel envelope incl. the 2026-05-02 peer_name/peer_role/agent_card_url enrichment fields, the /notify vs /a2a reply transport table, and the named limitations all match current behavior). Approved to merge once CI goes green — it's currently pending/queued. Will merge on the next pulse if checks pass.

One tiny note for the follow-up PRs you've named: when you add the typed org_id/origin constructor kwargs, please also add a deprecation-free changelog entry and a one-line README example update in the same PR so the workaround block can be trimmed. No change needed here.
