feat(pdftract-91e1i): HTTP fetch sequence implementation
...
Implement orchestration layer connecting HttpRangeSource to Phase 1.3
xref resolver and Phase 1.4 document model for remote PDF access:
- Document::open_remote() public API for remote PDF loading
- Progressive tail fetch (16 KB → 1 MB) for startxref location
- Xref forward-scan disabled for remote sources (via is_remote check)
- Page-by-page on-demand fetch via HttpRangeSource caching
- Resource lazy load through XrefResolver cache
- HEAD probe with 405 fallback, no Content-Length handling
Acceptance criteria:
✅ open_remote(url) returns Document with correct page count
✅ HEAD failure modes (405, no Content-Length, 401) handled
✅ xref forward-scan disabled for remote (is_remote check)
✅ Page-by-page on-demand fetch (HttpRangeSource LRU cache)
✅ INV-8 maintained (all errors return Result)
Files modified:
- crates/pdftract-core/src/document.rs (Document::open_remote, from_source)
- crates/pdftract-core/src/remote.rs (progressive tail fetch)
- crates/pdftract-core/src/lib.rs (re-exports)
