feat(mcp): add remote + stdio surfaces for loopover_get_gate_config_effective

[kai392]

Summary

• Closes loopover_get_gate_config_effective has a REST route but no remote MCP tool or local stdio MCP tool #7800: register loopover_get_gate_config_effective on remote MCP + local stdio (thin mirror of GET /v1/repos/:owner/:repo/gate-config/effective).
• Same canAccessRepo / MCP_READ_REPO_ALLOWLIST boundary as PR reviewability; returns effective thresholds + shadowPending.
• Declares outputSchema (chore(mcp): add outputSchema to tools that lack it #550) and adds forbid/empty/populated coverage in mcp-output-schemas so codecov/patch sees src/mcp/server.ts (fixes closed feat(mcp): add remote + stdio surfaces for loopover_get_gate_config_effective #7923/feat(mcp): add remote + stdio surfaces for loopover_get_gate_config_effective #7925).
• Pins stdio tool discovery count 86 → 87 (after feat(mcp): add remote + stdio surfaces for loopover_get_pr_maintainer_packet #7926 maintainer packet).

Scope

• The PR title follows type(scope): short summary Conventional Commit format.
• This PR is focused and does not mix unrelated backend, UI, MCP, docs, dependency, and deploy changes.
• This follows CONTRIBUTING.md and does not reintroduce GitHub Pages, VitePress, site/, or CNAME.
• I linked a currently open issue this PR resolves (Closes #7800).

Validation

• git diff --check
• npm run branding-drift:check
• npm run typecheck
• npm run build:mcp
• vitest --coverage on mcp-output-schemas + mcp-gate-config-effective + mcp-cli-gate-config-effective + mcp-tool-rename-aliases (63/63)
• Local patch coverage on changed src/mcp/server.ts / bin executable lines: 100% (13/13)
• Full unsharded npm run test:coverage deferred to CI
• New or changed behavior has unit/integration tests for new branches

If any required check was skipped, explain why:

• Full matrix deferred to CI after the local gates above passed (these are the exact failure modes from feat(mcp): add remote + stdio surfaces for loopover_get_gate_config_effective #7923/feat(mcp): add remote + stdio surfaces for loopover_get_gate_config_effective #7925: outputSchema, codecov/patch, tool-count pin, merge drift).

Safety

• No secrets/wallet/hotkey/coldkey/PAT exposure.
• Auth negative-path covered (forbidden outside allowlist).
• API/OpenAPI/MCP behavior updated and tested where needed.
• No visible UI changes (UI Evidence N/A).

UI Evidence

N/A — MCP/API only.

Notes

• Fresh PR after feat(mcp): add remote + stdio surfaces for loopover_get_gate_config_effective #7925 was auto-closed for codecov/patch + conflicts; rebased onto current main including feat(mcp): add remote + stdio surfaces for loopover_get_live_gate_thresholds #7924/feat(mcp): add remote + stdio surfaces for loopover_get_pr_maintainer_packet #7926.
• One-shot PR: will not push follow-up commits onto this branch after open.
