[Documentation] Add event catalog for off-chain developers

[AbelOsaretin]

Description

Events are critical for off-chain integration but lack documentation. A catalog would:

• List all emitted events
• Document event schemas
• Provide indexing guidance
• Include example queries

Recommendation

• Create EVENTS.md documenting all events
• Include field types and descriptions
• Add indexer configuration examples
• Document event filtering patterns

Severity

Low — Off-chain developer experience.

hi repo maintainer,

please let me take this issue and submit in Swift response well detailed.

I'll create an EVENTS.md catalog for Heliobond/contracts that lists every emitted event with field types, descriptions, and indexing guidance. I'll include indexer config examples and common event filtering patterns so off-chain developers can integrate faster.

i am ready, or pls assign me
