b535638104 feat(pdftract-2bsfc): implement document catalog parser with PageLabels number tree 
Implement the document catalog parser (/Root traversal) for PDF documents.
The catalog parser extracts all key entries from the document catalog
including Pages, Outlines, MarkInfo, StructTreeRoot, AcroForm, Names,
Metadata, PageLabels, OCProperties, OpenAction, AA, and Version.

Key structures:
- MarkInfo: parses /MarkInfo dictionary with is_tagged, user_properties, suspects
- PageLabelStyle: enum for all label styles (D, R, r, A, a)
- PageLabel: single page label with style, prefix, and start value
- PageLabelsTree: number tree parser for /PageLabels with /Nums and /Kids support
- OcProperties: stub for OCG implementation (delegated to dedicated bead)
- Catalog: main catalog struct with all required and optional fields

Number tree implementation:
- Parses /Nums arrays (leaf nodes with alternating key-value pairs)
- Supports /Kids arrays (internal nodes for recursive tree traversal)
- Provides get_label_with_start() and get_label() methods for lookup
- Correctly formats roman numerals (uppercase/lowercase) and letter sequences

All 27 tests pass including proptests for fuzzing robustness (INV-8).

17f581897f fix(pdftract-4iier): correct typo in scientific_paper README and fix xtask path handling 
- Fix typo: "scific_paper" -> "scientific_paper" in fixture path
- Fix xtask path resolution: use relative path ".." to access workspace root
- Fix xtask format string: remove unused profile_name placeholder
- Add workspace exclusion to xtask/Cargo.toml for standalone build

These are minor improvements to the existing per-profile README documentation
that was already created in commit 8b5dd4f.

- contract: Legal contracts with parties, effective date, term, signatures
- scientific_paper: Academic papers with title, authors, abstract, DOI, references
- slide_deck: Presentation slides with title, presenter, date, slide titles
- form: Fillable forms (degenerate case: uses Phase 7.4 form_fields)
- bank_statement: Bank statements with account info, period, balances, transactions
