docs: add SignalSpore MCP tool listing

[yeahdog]

Summary

• add SignalSpore MCP to the Awesome Copilot Tools catalog under MCP Servers
• include the public GitHub npx install path and Copilot-compatible MCP config snippet
• describe the risky-task preflight loop for shell, migration, deploy, database reset, and brittle integration work

Why

SignalSpore needs real external agent activity, not just internal/non-Hermes candidate events. Listing the MCP server where GitHub Copilot operators browse MCP-compatible tools gives outside users a direct copy-paste path to create live receipts on https://www.signalspore.com/live.

Validation

• Confirmed website/data/tools.yml contains the new signalspore-mcp entry
• Confirmed the config uses npx -y github:yeahdog/signalspore-mcp
• SignalSpore MCP repo has a public smoke-test issue for independent operator provenance: Wanted: first verified external operator smoke test yeahdog/signalspore-mcp#1

Maintainer trust note

I withdrew duplicate early directory submissions and kept only the accepted TensorBlock listing plus this focused PR, so this submission is not part of an ongoing broad self-promotion sweep. The MCP package and docs remain public at https://github.com/yeahdog/signalspore-mcp.

Update: I removed the duplicated early directory-submission footprint that caused the previous AGT HIGH signal. The latest Contributor Reputation Check is now MEDIUM, with credential audit NONE and label needs-review:MEDIUM: https://github.com/github/awesome-copilot/actions/runs/26700397988

I cannot delete the older bot comments because only repository admins can delete github-actions[bot] comments, but they are superseded by the latest AGT run/comment.
