chore(release): 1.0.7

- Fix Infinity anchorTimestamp repair on JSON round-trip (blocks extending
  to end-of-conversation now restored correctly instead of discarded)
- Fix nextBlockId calculation to use max(id)+1 instead of array length
- Rename internal prompt tag <dcp-message-id> to <dcp-id>
- Add regression tests for corrupted-block resilience (PR #3, @wassname)
- Update README with Contributors section
- Update CHANGELOG for 1.0.7
- Bump package.json to 1.0.7
