v0.3.1 — nested refs + TeamRef metadata

Bundles the 0.3.0 (nested refs) and 0.3.1 (TeamRef metadata) work into a single published release. 0.3.0 was never tagged; install 0.3.1 to get all of it.

Added

Nested reference objects (was 0.3.0)

Every odds, opportunity, and reference-list row may now carry optional structured ref objects alongside the legacy flat fields. All additive — clients on older API versions just see undefined and behave identically.

• New interfaces: TeamRef, SportRef, EntityRef, Team, Market, NestedRefs bundle
• Typed LowHoldOpportunity (was loosely typed before)
• NormalizedOdds, EVOpportunity, ArbitrageOpportunity, MiddleOpportunity extend NestedRefs
• ArbitrageLeg gains sportsbook_ref
• ClosingOdd gains market_ref + sportsbook_ref
• ClosingSnapshot gains home, away, sport_ref, league_ref
• Sport, League, Sportsbook gain numerical_id

TeamRef metadata (was 0.3.1)

TeamRef and the Team reference shape gain five optional metadata fields:

• logo — full CDN URL (~93% coverage)
• city, mascot, conference, division

All default to undefined. Older servers that omit them keep working.

Repo / packaging hygiene

• Add LICENSE (MIT) and SECURITY.md (hello@sharpapi.io)
• Author email updated support@ → hello@
• Fix README install + JSDoc import: package is @sharp-api/client (not @sharpapi/client)
• Strip sourcesContent from npm sourcemaps so the .map files no longer ship a full copy of src/index.ts. Tarball: 57.7 kB → 31.0 kB.
• Drop tests/ from the repo (kept locally for development); CI gate is now biome + tsc across Node 18/20/22

Compatibility

No existing field was renamed, retyped, or removed. Code on 0.2.x continues to compile.
