feat(mcp): register loopover_get_automation_state stdio tool

[xfodev]

Summary

loopover_get_automation_state already exposed a remote MCP tool (src/mcp/server.ts) and a maintain automation-state CLI verb, but had no local stdio MCP registration — unlike every other tool in its maintain family. This adds the missing stdio surface:

• registerStdioTool("loopover_get_automation_state", …) + its STDIO_TOOL_DESCRIPTORS entry in packages/loopover-mcp/bin/loopover-mcp.ts, mirroring the merged loopover_get_gate_config_effective sibling: ownerRepo input shape, apiGet proxy, toolResult wrapper.
• The stdio tool proxies the existing GET /v1/repos/:owner/:repo/automation-state route — the same route the remote tool and CLI already use. No new REST route, no new CLI verb, no src/mcp/server.ts change.

Tests

• test/unit/mcp-cli-automation-state.test.ts (new, in-process): drives the tool through a real MCP Client over InMemoryTransport against a fixture server, asserting the tool is listed and the proxied request hits the automation-state route.
• test/unit/mcp-tool-rename-aliases.test.ts: stdio tool-count pin bumped 89 → 90 (all three assertions) with a running-log comment.
• test/unit/mcp-output-schemas.test.ts: added the tool to the output-schema coverage set.
• Category-sync (mcp-tool-categories) and completion-spec parity (mcp-cli-completion-spec) tests pass unchanged.

UI Evidence

N/A — backend MCP tooling only; no apps/** files touched.

Validation

• Root tsc --noEmit clean (my files).
• mcp-tool-rename-aliases, mcp-tool-categories, mcp-output-schemas, mcp-cli-completion-spec pass; the live server registers exactly 90 tools.
• Rebased on latest main; no base conflict.
• No wallet/hotkey/trust-score/reward terms in tool output.

Closes #7752

Superseded — #7752 was merged upstream while this was in CI; loopover_get_automation_state is already registered on main. Closing as a duplicate.
