[hyperpolymath]

Adds a Signed commits section to this repo's CONTRIBUTING, per owner ruling D218. The estate policy is docs/SIGNING-POLICY.adoc in hyperpolymath/standards.

This repo's default branch is covered by the zero-bypass Require-Signed-Commits ruleset, and rebase-merge is off. The section tells contributors what that requires:

• People and interactive agents sign with an SSH signing key.
• Apps, bots and workflows write through the API, so GitHub signs their commits.
• PRs are merged with squash.

If the file already had its own signing section, that section is replaced in place instead of adding a second one. Lines elsewhere that told people to sign with GPG are changed to match the policy (SSH for people).

This is a docs-only change. The commit was created through createCommitOnBranch, so GitHub signs it.

📝 Summary

Summary by CodeRabbit

• Documentation
  • Added contribution guidance requiring commits to the default branch to be signed with a registered SSH signing key and verified committer email.
  • Clarified that automated tools must use approved signed-push methods.
  • Documented that pull requests must be squash-merged, unsigned commits on pull request branches prevent merging, and rebase merging is unavailable.

Walkthrough

The contribution guide now requires signed commits and explains signing methods for people, interactive agents, apps, bots, and workflows. It also specifies squash merges and states that unsigned commits block merging.
