feat(mcp): governed MCP ops surface — agent-native, fail-closed, hash-sealed (march #1) - #16

…-sealed (march #1) Closes#15. Superiority-march move #1: closes the #1 competitive gap (agent-native MCP ops surface — 8 competitors ahead) while keeping the properties the SaaS incumbents (Qovery, Port, Render, ...) lack. tools/mcp_ops_server.py — a minimal stdio JSON-RPC (MCP) server, ZERO external deps, exposing continuum's owned surface as agent-callable tools (list CapD capabilities, lifecycle status, list evidence, run the promotion gate). Drivable by Claude Code / Cursor. Our open edge, all shipped here: - FAIL-CLOSED by default: read tools run; guarded tools are REFUSED unless an explicit policy grant (CONTINUUM_MCP_ALLOW_GUARDED) is present — never execute-then-audit. - A HASH-SEALED receipt on EVERY call (allow or refuse) in the evidence bundle — a tamper- evident ledger, not a mutable audit log. - FULLY OPEN: MIT, self-hosted, stdio, no SaaS, no dependency, scale-to-zero. Consumes (not reimplements): the review verdict via tools/promotion_gate.py. `make mcp` runs it; validate.py requires it. Verified: initialize/tools/list/tools/call over real stdio; read tools seal + return data; guarded tool refused fail-closed without a grant, runs with one; 8 tests green.

Closes#15 · Superiority-march move #1 (closes the #1 gap in the DevSecOps intelligence register).
Agent-native MCP ops surfaces are now table stakes (Qovery, Port, Render, Railway, Coolify, Heroku, Backstage, Kratix) — continuum had none. This ships one, and does it better and open:
tools/mcp_ops_server.py— minimal stdio JSON-RPC MCP server, zero external deps, exposing continuum's owned surface (CapD capabilities · lifecycle · evidence · promotion gate). Works with Claude Code / Cursor.Verified end-to-end over real stdio (initialize → tools/list → tools/call): read tools seal + return; guarded tool refused fail-closed without a grant, runs with one.
make validategreen, 8 tests. Consumes the review verdict viapromotion_gate.py(not reimplemented).
