feat(hermes): verified Hermes earning integration (#772)

[brok-best]

Summary

Implements [DIRECT] Hermes earning integration for issue #772.

• Canonical skill: add exact hosted claimable feed URL (discovery still prefers check-in / claimable-live; warns label:bounty is not claimability)
• integrations/hermes/README.md: one-command hermes skills install of upstream SKILL.md + --now//reset activation
• Fixtures: claimable / unfunded / stale with one distinct next_action each
• scripts/check-hermes-integration.py smoke

Test plan

• python scripts/check-hermes-integration.py
• WORKSPACE_ROOT=. python benchmarks/direct-growth-v2/hermes-integration/check.py

Thanks for contributing the Hermes earning integration, and sorry for the review delay. The claimable, unfunded, and stale fixtures with deterministic next actions are useful. Thank you for helping the community grow.

Status: manual-security-review / request-changes

What passed:

• Clear installation and activation path.
• Useful inventory-state coverage.
• Correct separation between claim/submission evidence and payment evidence.

What blocks main:

• This changes the canonical skill and adds an executable script, so it needs manual review.
• It overlaps [DIRECT] Add a verified Hermes earning integration #800, feat: add verified Hermes earning integration #790, feat: Hermes Agent earning integration for agent-bounties (#772) #784, and [#772] Hermes Agent Bounties integration #781. We need one canonical Hermes contract.

Repair path:

• Coordinate with those authors and state why this PR should be canonical, or narrow it to missing behavior.
• Run python scripts/check-hermes-integration.py, python benchmarks/direct-growth-v2/hermes-integration/check.py, and cargo run -p cli -- docs-contract-check.
• Add a test rejecting stale or unfunded inventory as claimable and requiring BountySettled before reporting payment.

Branch path: keep this PR focused; no collaboration branch until the script and skill changes are reviewed.

Done when: duplicates are superseded or scoped, checks pass, and a maintainer rechecks the final skill and script.

This review does not approve merge, bounty acceptance, payout, or payment settlement.
