feat: add optional team_side + market_segment to odds/EV/closing models (#76, #689)

Surfaces the structured side + segment axes the API now emits (sharp-api-go
#76 Phase C / #689). OddsLine, EVOpportunity, and ClosingOddsLine each gain
optional team_side ("home"|"away"|"draw") and market_segment ("full_game",
"1st_half", ...). Additive, default None — existing code unaffected; the API
keeps emitting compound selection_type for back-compat.

Bump 0.3.3 → 0.3.4.

+## 0.3.4 — 2026-06-02
+
+### Added — structured `team_side` + `market_segment` (issue #76 / #689)
+
+- `OddsLine`, `EVOpportunity`, and `ClosingOddsLine` gain two optional fields:
+  - `team_side` — the raw structured side (`"home"` | `"away"` | `"draw"`)
+    decomposed out of the compound `selection_type` vocabulary. Prefer this over
+    parsing compound prefixes like `"home_over"`.
+  - `market_segment` — the canonical contest slice (`"full_game"`, `"1st_half"`,
+    `"1st_5_innings"`, ...).
+- Both are additive and default to `None`; existing code is unaffected. The API
+  continues to emit the compound `selection_type` for back-compat.
