test(pdftract-3g6ne): add Identity-H/V round-trip tests

Adds test_identity_h_roundtrip and test_identity_v_roundtrip tests
to fully satisfy the final acceptance criterion for round-trip with
Identity-H CMap fixture.

Tests verify:
- Single 2-byte codespace range covering all 16-bit codes
- Correct parsing of <0000> <FFFF> range
- find_range() correctly identifies codes within the range

feat(pdftract-3g6ne): implement CMap codespace range parser

Details

This commit adds the codespace range parser for CMap streams. The parser
extracts the begincodespacerange / endcodespacerange blocks that define
legal byte-width boundaries for character codes in a CMap.

## Implementation

- CodespaceRange: Single range with lo/hi bounds (stored as [u8; 4]) and width (1-4 bytes)
- CodespaceRanges: Collection with SmallVec<[CodespaceRange; 8]>
- CodespaceParser: PostScript-style tokenizer for begincodespacerange blocks

## Acceptance Criteria (all PASS)

- Parse <00> <7F> → 1 range, width=1 ✅
- Parse <00> <7F> <8000> <FFFF> in one block → 2 ranges ✅
- Width inference: 2-char hex → width=1; 4-char hex → width=2 ✅
- Case-insensitive hex (<C0> and <c0> equivalent) ✅
- Malformed range (width mismatch) → diagnostic + skipped ✅
- Empty CMap → empty ranges ✅
- JIS range <8140> <FEFE> → 2-byte CJK ✅
- 3-byte and 4-byte range support ✅

Also adds encrypted fixture provenance entries to PROVENANCE.md.
