- Add IdlEvent struct to SpelIdl with name, discriminant, fields - Add events: Vec<IdlEvent> field to SpelIdl (backward-compatible) - Add #[event(discriminant = N)] proc macro attribute - Add with_events() builder to SpelOutput - Wire event parsing into generate_idl_json and generate_idl_fn - Add lez-events dependency to spel-framework-core - Update spel-client-gen tests for new SpelIdl field - All 90 tests passing This enables programs to annotate event payload structs with enabling spel tx decode to do full typed event decoding.

Rebased onto upstream/main (d24dbaa, v0.4.0). Conflicts resolved , removed the lez-events crate dependency, keeping IdlEvent and #[event] as self-contained additions to spel-framework-core and spel-framework-macros. All 225 unit tests passing, 0 failures. |

Adds #[event] macro and IDL event schema support, enabling spel tx decode to do full typed event decoding from transaction receipts.
Changes:
IdlEvent struct added to SpelIdl (name, discriminant, fields: Vec)
events: Vec field in SpelIdl — backward-compatible, skipped if empty
#[event(discriminant = N)] proc macro to annotate event payload structs
SpelOutput::with_events() builder that auto-drains the lez-events buffer
generate_idl_json and generate_idl_fn pick up #[event] structs alongside #[instruction] functions
All 90 existing tests passing
Usage:
rust#[event(discriminant = 1)]
pub struct InsufficientFunds {
pub requested: u128,
pub available: u128,
}
