feat(bf-1g1fd): implement CI memory-ceiling gate with cgroup MemoryMax enforcement

Implements Tier-1 memory ceiling gate that enforces RSS budgets for PDF
extraction, analogous to cargo-bloat for binary size.

Changes:
- CI: Add memory-ceiling template with cgroup MemoryMax (1.5 GB)
- CI: Add cgroup MemoryMax enforcement to test-glibc (6 GB) and test-musl (4 GB)
- CI: Add cgroup MemoryMax + libfuzzer rss/malloc limits to fuzz workflow
- xtask: Implement memory-ceiling command with peak RSS sampling
- Add perf fixtures (100-page, 10k-page) for memory testing
- Add run-fuzz-with-limits.sh for local fuzz testing with memory caps
- Register perf fixtures in PROVENANCE.md

Memory budgets enforced:
- Buffered 100-page PDF: < 512 MB
- Streaming mode: < 256 MB (constant in page count)
- Adversarial fixtures: < 1 GB hard ceiling

Closes bf-1g1fd

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).
