feat(namespace): add GeoRSS, Creative Commons, and ParseOptions API

[bug-ops]

Summary

Implements Phase 1 of feedparser parity gap analysis to close gaps between feedparser-rs and Python feedparser.

New Features

• GeoRSS namespace support for geographic location data

  • Supports georss:point, georss:line, georss:polygon, georss:box elements
  • Coordinate validation (lat: -90 to 90, lon: -180 to 180)
  • GeoType enum and GeoLocation struct

• Creative Commons namespace for license metadata

  • Supports cc:license with rdf:resource attribute
  • Supports legacy creativeCommons:license text element
  • Converts licenses to links with rel="license"

• ParseOptions API for parser configuration

  • resolve_relative_uris: URL resolution control
  • sanitize_html: HTML sanitization toggle
  • limits: ParserLimits integration
  • Presets: default(), strict(), permissive()

• Enhanced date parsing

  • Year-only format ("2024")
  • Year-month format ("2024-12")

Files Changed

• crates/feedparser-rs-core/src/namespace/georss.rs - GeoRSS namespace handler
• crates/feedparser-rs-core/src/namespace/cc.rs - Creative Commons handler
• crates/feedparser-rs-core/src/options.rs - ParseOptions API
• crates/feedparser-rs-core/src/util/date.rs - Additional date formats
• crates/feedparser-rs-core/src/types/entry.rs - Added geo field
• crates/feedparser-rs-core/src/namespace/mod.rs - Module exports
• crates/feedparser-rs-core/src/lib.rs - Public API exports

Test plan

• All 441 tests pass (cargo nextest run --workspace)
• Clippy clean (cargo clippy --all-features --workspace -- -D warnings)
• New namespaces have unit tests with coverage
• ParseOptions presets work correctly
