## Description

<!-- SECTION:DESCRIPTION:BEGIN -->
Translate the three commitment issuance channels from Python to Solidity. These enable non-financial token minting paths for community economies.

1. Labor Issuance (src/commitments/labor.py):
- Attestation oracle verifies work → mint tokens at governed rate
- Rate-limited per attestor per time window
- Integrates with WeaveRegistry from payment-infra (commitment types: Dev Hours, Design, Facilitation)
- CommitmentToken.sol (ERC-1155) already exists in payment-infra

2. Subscription DCA (src/commitments/subscription.py):
- Recurring pledges with loyalty multipliers
- Time-weighted minting (longer subscription → better rate)
- Chainlink Automation for recurring execution

3. Staking Lockups (src/commitments/staking.py):
- Duration-weighted bonus minting: sqrt concave curve
- Lock collateral for N days → receive bonus tokens
- Integrates with LST staking yields from cross-chain module

All channels feed into the bonding curve reserve, increasing collateral backing for tranches.

## Acceptance Criteria
<!-- AC:BEGIN -->
- [ ] #1 Labor attestation mints tokens at governed rate
- [ ] #2 Subscription DCA executes recurring buys via Chainlink Automation
- [ ] #3 Staking lockup calculates duration bonus correctly
- [ ] #4 All channels increase bonding curve reserve
- [ ] #5 Rate limiting prevents spam minting
