feat(mcp): single-connector default set + connector policy (#2219)

Reduce the default .mcp.json to one connector (chrome-devtools) per the
new policy in docs/MCP-CONNECTOR-POLICY.md: a default earns its slot only
if it is universal AND MCP beats a CLI/API wrapped in a skill. June 2026
audit verdicts: github -> gh via github-ops skill; context7 -> REST via
documentation-lookup; exa -> harness-native search (+ exa-search skill);
memory -> native harness memory + instincts; playwright -> playwright CLI
skills (vendor moved agent flows off MCP); sequential-thinking -> native
extended thinking. All six remain opt-in in mcp-configs/mcp-servers.json.
Tests updated: plugin-manifest policy assertions + install-apply Cursor
expectations.

# Changelog
## Unreleased
### Changed
- Default MCP connector set reduced to a single connector (`chrome-devtools`) per the new connector policy (`docs/MCP-CONNECTOR-POLICY.md`). The six previous defaults (`github`, `context7`, `exa`, `memory`, `playwright`, `sequential-thinking`) were retired after the June 2026 audit: their jobs are covered by skills wrapping CLIs/REST APIs (`github-ops`, `documentation-lookup`, `exa-search`, e2e skills) or by harness-native features (memory, extended thinking, web search). All six remain opt-in via `mcp-configs/mcp-servers.json`.
