- Packed id via one BigInt hex format instead of four 16-bit segments (~1.7x faster).
- Extracted timestamp via exact double arithmetic, dropping BigInt round-trip.
- Lazily initialized the default source.
- Added round-trip and ordering tests across packing boundaries.
- Added import of expandRoleAlias function from model-resolver module.
- Added role alias expansion step before parsing model strings in model resolution logic.
- Fixed u32 overflow in snowflake ID generation by keeping values in Number space instead of relying on bitwise operations that cause integer truncation.
- Simplified snowflake generation by replacing bigint arithmetic with 32-bit number operations and hex lookup table.
- Removed configurable epoch from Source constructor, using fixed EPOCH constant instead.
- Renamed Source.next() method to generate() and removed source parameter from module-level functions.
- Removed getMachineId() function which was unused in non-distributed snowflake implementation.
- Simplified getSequence() and getTimestamp() implementations to use direct hex parsing instead of bigint operations.
- Replaced nanoid and randomUUID with Snowflake ID generator across codebase for consistent distributed ID generation.
- Created new Snowflake utility module in packages/utils with support for 64-bit distributed ID generation with configurable epoch, machine ID, and sequence numbers.
- Updated session ID format documentation from nanoid to snowflake hex string format (16 hex characters).
- Removed nanoid dependency from package.json as it is now replaced by internal Snowflake implementation.
