* fix(pptx): harden import resource budgets, deduplication, and lookup caching
- Chart sidecars (Finding 2): Enforce an import-wide retained byte budget
and cache captured sidecars by chart part to prevent memory amplification.
- Content types cache (Finding 6): Cache parsed [Content_Types].xml defaults
and overrides in Package.ct_cache.
- Text run splitting and font lengths (Finding 8): Bound typeface attribute
lengths and cap paragraph runs to prevent multiplication on text splitting.
- Inner namespace decls (Finding 15): Use HashSet/HashMap indexing and cap
inner declarations to 1,000.
- Slide and notes deduplication (Finding 16): Deduplicate slide paths and
cache parsed notes slide bodies by target.
- Diagram media caching (Finding 22): Cache diagram media payloads in
imp.media_by_part.
- Master slide deduplication (Finding 28): Deduplicate master paths before
loading.
- Layout target deduplication (Finding 30): Deduplicate layout targets
across master slides.
- Chart value axis indexing (Finding 32): Index valAx by axId using a HashMap.
- ChartEx series output budget (Finding 34): Charge series point vectors
against an aggregate output budget and cap series count.
- ChartEx point allocation bounds (Finding 36): Allocate point vectors
only to actual point span bounded by budget rather than declared ptCount.
- SmartArt recursion depth (Finding 38): Limit SmartArt recursion depth to 8.
* fix(pptx): address review feedback on sidecar cache, series budget, and inner decls
* fix(pptx): preserve cached sidecar bytes and non-empty category fallback
- Row 31: Use HashMap for comment author lookup in author_slot
- Row 37: Index preserved parts by ID before resolving graphic frame relationships
- Row 10: Index kept chart parts by normalized path and avoid duplicate payload scans
- Row 39: Update existing relationship parts instead of appending duplicates in PackageOut
* fix(metafile): harden EMF+ parsing, clipping complexity, and memory accounting
- Row 72: Use checked tail slicing in comment header offset calculations
- Row 78: Break FillRects and DrawRects loops early when canvas is full
- Row 75: Pre-check dimensions in decode_compressed before RGBA pixel allocation
- Row 85: Account for EMF+ object table image/path memory against MAX_BYTES
- Row 42: Replace O(N^2) prefix copying in wrap_line with linear measurement
- Row 43 & 54: Share immutable clip regions Arc across placed items and charge canvas regions
- Row 48: Bound text transformation scale and glyph curve geometry in Picture::place and draw_text
- Row 52 & 68: Impose work budget bounds on Sutherland-Hodgman polygon clipping and bitmap masking
* fix(metafile): collapse nested if statement per clippy
Skipped where the receiver type is generic or not evident without a compiler (wrapping_neg, total_cmp, exists, to_vec, as_ref, split_first, Option::into_inner).
