Expand Error Taxonomy Features

[codeZe-us]

The Error Taxonomy Database requires extensive metadata to be truly helpful to developers, including documentation links, protocol versioning, related errors, and explicit contract-specific examples.

Issues/what to fix

• Add a "Related Errors" linking system to connect similar failure modes.
• Implement a "Stellar Documentation" URL field for direct links to Soroban official docs.
• Add "Since Protocol" versioning fields to track when errors were introduced or changed.
• Backfill the database with 50+ real-world contract-specific error examples.

Files location

crates/core/src/taxonomy/schema.rs, taxonomy_db/ (or wherever the taxonomy data is stored)

Expected result

The taxonomy database is fully populated with rich metadata, turning basic error codes into highly actionable, extensively documented developer resources.
