Purpose

Closes #23. Depends on #34; merge #34 first.

Complete the HTTP factory migration after removal of the duplicate JSON-RPC
sidecar. Official MCP 2.x remains the sole owner of /mcp; NitroStack supplies
the application handlers, transport configuration, CORS, and era policy.

This update also addresses the review identifying four test-collection errors
and two additional full-suite failures.

Changes

• Migrated tests of deleted dispatch/replay classes and ping helpers to requests
  through the official MCP HTTP application. Kept pure parser, header, CORS,
  SSE, protocol-contract, and response-echo coverage.
• Kept the test-module importability registry enabled. All registered modules
  now import successfully; no sidecar compatibility shims were restored.
• Merged current upstream develop normally. This includes the existing
  supported-version expectation fix for 2025-11-25; no protocol dates or era
  aliases were added or removed by this update.
• Applied one subscription-support predicate to discover, server capabilities,
  and subscription handlers: legacy compatibility remains enabled; auto and
  modern advertise false and reject subscribe/unsubscribe requests.
• Configured each server's era before transport startup, including additional
  server instances and stdio capability negotiation.
• Applied initialization/version policy through public MCP Server.middleware
  on already-parsed request contexts. No JSON-RPC body parsing, buffering, or
  response generation was added to ASGI middleware. Compatible headerless
  requests retain the SDK's implicit legacy fallback.
• Retained one HTTP factory and CORS layer, configured origin allowlists,
  era-driven /json/version, session-manager selection, health/slash handling,
  and public stdio runner APIs.
• Added AST and behavioral stdio regressions for private imports, modern calls,
  legacy initialization, notifications, and initialization rejection.

Verification

MCP version tested: 2.2.0.

Hosted CI: all checks passed

Python SDK Test Suite run 40511981383
completed successfully on final head 71e47f1:

Linux CI job	Tests	Coverage
Python 3.10	809 passed	86.20%
Python 3.11	809 passed	86.18%
Python 3.12	809 passed	86.11%

No skipped tests, xfails, ignored files, or deselections were used.

Local cross-platform verification

Environment	Full suite	Coverage
Windows, Python 3.12.14	807 passed	86.02%
Ubuntu/WSL, Python 3.10.21	807 passed	86.04%
Ubuntu/WSL, Python 3.11.16	807 passed	86.02%
Ubuntu/WSL, Python 3.12.14	807 passed	86.02%

These are complete runs with no ignored files, deselections, skips, or xfails.
Two pre-existing pure utility checks were subsequently restored and passed
separately on all four runtimes. Final collection is 809 tests, with no
collection errors; the completed hosted matrix above ran all 809 together.

• Six reviewer-reported test modules: 225 passed, before the two final
  utility checks were restored.
• Original issue verification command: 34 passed.
• Issue [mcp-2026] Remove JSON-RPC sidecar; one /mcp owner (official mcp 2.x) #22/[mcp-2026] Unify HTTP factory: CORS once, subscribe flag, public stdio APIs #23 ownership/factory and related HTTP/stdio/deprecation checks:
  76 passed.
• git diff --check passed.

[Shreyavemana]

I tested PR #36 locally.

• The issue verification tests pass (46 passed).
• However, the full test suite fails: four test files fail during collection because of removed modules/functions, and two additional tests fail after excluding them:
  • test_mcp20_blueprint.py — missing nitrostack.transports.dispatch
  • test_mcp20_deprecated.py — missing nitrostack.transports.dispatch
  • test_mcp20_jsonrpc_wire.py — missing nitrostack.transports.dispatch
  • test_mcp20_stateless_http.py — cannot import build_ping_response

(Additional failed test after removing the above ones)

• test_mcp20_test_modules_importable
• test_supported_versions_per_era

Please address the remaining test failures and rerun the full test suite.
