Doc-only patch preparing the ground for v0.16's bundled HttpMcpConnector
class. No code change; three documentation surfaces updated to acknowledge
MCP-over-HTTP (Streamable HTTP + SSE) as a first-class transport option
alongside the stdio path that RemoteMcpConnector covers today.

Per Perry sign-off on the v0.16.0 charter (thread 0b35bd70): two-stage
ship is right — doc fix has value today, don't fold into v0.16.0.

docs/adopter-playbook.md §Case 2

Pre-v0.15.6, the section implied RemoteMcpConnector (stdio) was THE
MCP path. Rewritten to articulate transport as a separate concern from
the wire protocol: stdio (RemoteMcpConnector for community servers
like YouTrack, GitHub, Linear) vs. HTTP (Anthropic's hosted MCP, AMP,
spec-compliant HTTP servers). For HTTP, two sub-paths with their
tradeoffs: stdio-bridge via mcp-remote --sse (works today, adds
subprocess) vs. direct HTTP connector class (lower overhead, requires
implementation).

examples/onboarding-scaffold/connectors.json

New comment on the _example_remote_mcp entry: explicitly notes that
the same mcp-remote --sse pattern bridges Streamable HTTP MCP servers
(Anthropic hosted MCP, AMP, etc.) — discoverability fix so adopters
scanning the example see the wider applicability.

examples/connectors/McpConnectorTemplate/README.md

Updated "Fork this template only when none of those fit" list:

• Direct HTTP MCP retained as a forkable case for now, with a forward
  note that a bundled HttpMcpConnector is on the near-term roadmap
  (timeless framing — readers on the version that ships HttpMcpConnector
  will see it bundled; readers pre-that-version see the fork path)
• Added explicit guidance for HTTP MCP servers: stdio-bridge path is
  the simplest today; check for bundled HttpMcpConnector before
  forking

Phase 4 dogfood reframing (banked as project memory)

Bundling HttpMcpConnector in v0.16.0 collapses the Phase 4 cold-adopter
dogfood from implementation-validation (fork template + implement
HTTP-MCP from scratch) to configuration-validation (declare an instance
in connectors.json pointing at the endpoint). Still worth doing as a
matrix-validation lane — AmpSkillStore + AmpDataStore + bundled
HttpMcpConnector configured against AMP + skills exercising the full
toolbox, end-to-end — but cheaper. Banked as
project_phase4_dogfood_reframe for future phase planning.

Perry's structural framing: v0.16 charter = "structural discipline" —
HttpMcpConnector + the runtime_capabilities contract-test fixture
(from thread adf47c0b) both prevent the discipline-only-contracts
class. Defer language features to v0.17. Tight charter, clean narrative.
