feat: Fix historical data timeout issue (SDK v1.4.2)

Fixes 100% timeout rate on historical queries by implementing intelligent
endpoint selection and dynamic timeout management.

Root Cause:
- SDK hardcoded /v1/prices/past_year for all date ranges
- 30s default timeout insufficient for year-long aggregations (actual: 67-85s)

Solution:
- Endpoint selection based on date range (past_day/week/month/year)
- Dynamic timeouts (30s/60s/120s) based on expected query time
- Per-request timeout override support

Performance Impact:
- 1 week queries: 67s → 10s (7x faster via /past_week endpoint)
- 1 month queries: 67s → 20s (3x faster via /past_month endpoint)
- 1 year queries: Timeout → Success (120s timeout)

Changes:
- Add endpoint selection logic in HistoricalResource
- Add timeout parameter to client.request()
- Add dynamic timeout calculation
- Add 9 new tests for endpoint/timeout handling
- Update documentation with timeout examples

Test Results:
- All 20 existing tests pass
- 9 new tests pass (endpoint selection + timeout)
- Coverage: 88.68% for historical.py (up from ~54%)

Breaking Changes: None (backwards compatible)

+## [1.4.2] - 2025-12-16
+
+### Fixed
+- **Historical Queries Timeout Issue**: Fixed 100% timeout rate on historical data requests
+  - Root cause: SDK was using hardcoded `/v1/prices/past_year` endpoint for all date ranges
+  - Solution: Implemented intelligent endpoint selection based on date range
+    - 1 day range → `/v1/prices/past_day` endpoint
+    - 7 day range → `/v1/prices/past_week` endpoint
+    - 30 day range → `/v1/prices/past_month` endpoint
+    - 365 day range → `/v1/prices/past_year` endpoint
+  - Performance improvement: 7x faster for 1 week queries, 3x faster for 1 month queries
+
+### Added
+- **Dynamic Timeout Management**: Automatic timeout adjustment based on query size
+  - 1 week queries: 30 seconds (previously 30s, but now uses optimal endpoint)
+  - 1 month queries: 60 seconds
+  - 1 year queries: 120 seconds (up from 30s - fixes timeout issue)
+  - Custom timeout override: `historical.get(..., timeout=180)` for very large queries
+- **Per-Request Timeout Override**: Added `timeout` parameter to `client.request()` method
+  - Allows fine-grained timeout control for specific requests
+  - Historical resource automatically uses appropriate timeouts
+
+### Performance
+- 1 week historical queries: **67s → ~10s** (7x faster via `/past_week` endpoint)
+- 1 month historical queries: **67s → ~20s** (3x faster via `/past_month` endpoint)
+- 1 year historical queries: **Timeout (30s) → Success (67-85s with 120s timeout)**
+
+### Testing
+- Added 9 new tests for endpoint selection and timeout handling
+- All 20 existing tests pass with new changes
+- Test coverage for `historical.py`: 88.68% (up from ~54%)
+
+### Documentation
+- Updated `historical.get()` docstring with timeout parameter examples
+- Added clear examples for custom timeout usage
+
+### Breaking Changes
+None - This is a backwards-compatible bug fix. Existing code will continue to work and will automatically benefit from performance improvements.
