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

OddsLine, EVOpportunity, ClosingOddsLine each gain optional team_side
("home"|"away"|"draw") + market_segment ("full_game","1st_half",...). Surfaces
the structured axes the API now emits (sharp-api-go #76 Phase C / #689).
Additive, default None. Bump 0.4.0 → 0.4.1.

+## 0.4.1 — 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.
