Fix #164: Update to permission (singular) for opencode v1.1.1+ compatibility

- Changed 'permissions:' to 'permission:' in all 16 agent files
- Updated documentation to reflect new standard:
  - agent-frontmatter.md: Updated examples and validation rules
  - subagent-structure.md: Updated all permission patterns
  - tool-permission-errors.md: Updated examples
  - subagent-prompt-structure.md: Updated template
- Follows opencode v1.1.1+ specification
- Maintains backward compatibility (tools config still supported)
- Permission evaluation: last matching rule wins
