This commit completes Phase 5.2.2 by integrating the pdfium-render path
into serve mode with runtime validation and feature propagation.
Changes:
- Propagate ocr and full-render features from CLI to pdftract-core
- Add full_render parameter to serve mode ExtractParams
- Implement runtime validation in build_options():
* Returns BadRequest if full_render requested but PDFium unavailable
* Falls back to direct compositing if feature not compiled
- Update all three serve handlers to handle Result from build_options()
Acceptance Criteria:
✅ cargo build --features ocr,serve,full-render succeeds
✅ cargo build --features ocr,serve (no full-render) succeeds
✅ Runtime fallback: full_render=true with feature absent uses direct path
Notes:
- Binary size CI gate (140 MB) requires separate CI infrastructure
- Soft-mask regression tests require separate fixture work

Implement FontKind enum and classify_font() function for Phase 2.1
font type detection. Includes strip_subset_prefix() for handling
font subset names (e.g., ABCDEF+Times-Roman).
FontKind variants:
- Type1, Type1Std14 (Standard 14)
- TrueType, OpenTypeCFF
- Type0, CIDFontType0, CIDFontType2
- Type3
Classifier reads /Subtype, /BaseFont, and for Type0 fonts, descendant
CIDFont subtype. OpenTypeCFF detected via /FontDescriptor /FontFile3
with /Subtype /OpenType.
All 27 font tests pass.

Add 4 new tests to verify PNG and TIFF predictor functions use row-by-row
processing with bounded peak memory (2x stride), never pre-allocating full
output buffers inside tests.
- test_png_predictor_budget_enforcement_small_fixture: 200-byte fixture,
100-byte budget, verifies truncation at row boundary
- test_tiff_predictor_2_budget_enforcement_small_fixture: 160-byte fixture,
80-byte budget, verifies row-by-row processing for grayscale
- test_png_predictor_multiple_selectors_budget_per_row: 25-byte fixture
with all PNG selector types, verifies per-row budget checking
- test_tiff_predictor_2_rgb_budget_enforcement: 45-byte RGB fixture,
verifies multi-byte pixel handling with budget enforcement
All fixtures are under 250 bytes, no full-buffer pre-allocation, tests
mirror the row-by-row discipline from bf-49wmw production fix.
Closes bf-21hw8
- Add decode_page_content_streams() function for per-page lazy decode
- Update extract_page_from_dict() to support lazy stream decoding
- Modify extract_pdf() and extract_pdf_ndjson() to enable lazy decoding
- Fix borrow checker issue in LazyPageIter::next()
This ensures content streams are decoded lazily per page and dropped
immediately after processing, keeping peak RSS flat across page count.

- 12 exported symbols verified via nm -D
- C client tests (test_api.c, test_api_null.c)
- C++ client test (test_extract.cpp)

Add cbindgen infrastructure to auto-generate C/C++ header from Rust extern
"C" surface at build time.
- Add cbindgen.toml config (C language, include guard, pragma_once, cpp_compat)
- Add build.rs to generate include/pdftract.h during cargo build
- Generated header compiles cleanly with gcc (C) and g++ (C++)
The header is the contract between libpdftract and C/C++ consumers.
Future extern "C" functions will automatically appear in the header.

The detail field truncation in human.rs only applied to TTY output,
causing lines to exceed 80 columns when piping to cat or using --no-color.
Fix: Apply truncation uniformly across all output modes:
- TTY mode: Use actual terminal width from terminal_size crate
- Non-TTY/--no-color: Assume 80 columns and truncate accordingly
- Detail field max width: term_width - 38 columns
Max line width now exactly 80 characters for all output modes.
Acceptance criteria verified:
- TTY colored table with summary ✓
- Non-TTY plain text, no ANSI ✓
- --json single JSON object ✓
- --json summary counts ✓
- --features list, exit 0 ✓
- --no-color plain text in TTY ✓
- 80-column terminal width ✓
- N/A excluded from human, in JSON ✓

- PASS: --json output parses correctly with jq
- PASS: --features lists compiled features, exit 0
