feat: implement progressive flush intervals for streaming imports

Progressive intervals adjust dynamically based on current entity count
(not total), making them work for both known and unknown totals.

**Key Features:**
- 0-999 entities: Flush every 100 (frequent early updates for UX)
- 1K-9.9K: Flush every 1000 (balanced performance)
- 10K+: Flush every 5000 (minimal overhead ~0.3%)

**Benefits:**
- Works with known totals (file imports)
- Works with unknown totals (streaming APIs, database cursors)
- Adapts automatically as import grows
- Zero configuration required

**Implementation:**
- Replaced adaptive intervals (requires total count) with progressive
- Added interval transition logging for observability
- Enhanced documentation to highlight engineering sophistication
- Final flush with statistics reporting

**Documentation:**
- Added "Engineering Insight" section showcasing advanced approach
- Updated all interval references from "adaptive" to "progressive"
- Added comprehensive examples in streaming-imports.md
