Release 0.2.0

Release 0.2.0

Spec Compliance Fixes

• IP addresses rejected in DID URLs per spec (parse_did_url() and parse_url())
• Resolved DID validated against DID Document id (Read/Resolve step 6)
• DID portability enforced: id changes require portable: true and previous
  DID in alsoKnownAs
• versionTime ordering uses strict greater-than (equal timestamps rejected)
• Query parameter mutual exclusivity enforced at parse time (versionId,
  versionTime, versionNumber)
• Witness {} and watchers [] correctly treated as "not configured" instead of
  erroring
• Empty arrays for watchers, nextKeyHashes, updateKeys no longer error in
  diff calculation
• Parameters1_0.deactivated changed from bool to Option<bool> for lossless
  serialization round-trips

Improvements

• resolve() conditionally downloads did-witness.json only when witnesses are
  configured (eager_witness_download parameter)
• prelude module added for convenient imports (use didwebvh_rs::prelude::*)
• NotFound and UnsupportedMethod error variants now carry context strings
• All unwrap() calls in production code replaced with proper error handling
• Deduplicated log entry spec implementations via impl_log_entry_common! macro
  (~150 lines removed)
• Deduplicated resolver helpers (validate_log_entries(), resolve_witness_proofs())
• Simplified Parameters::validate() (removed dead code, consolidated TTL validation)

New

• Benchmark harness: cargo bench --bench did_benchmarks (Criterion) and nightly
  benchmarks
• WebVHURL::to_did_base() helper for DID comparison without query/fragment

Maintenance

• Dependencies updated: affinidi-data-integrity 0.3→0.4, criterion 0.5→0.8,
  ssi 0.14→0.15, rand 0.9→0.10
• Fixed minimum Rust version badge in README (1.88→1.90)
• generate_history example uses deterministic timestamps; fixes rand 0.10 import
• Comprehensive test coverage: 353 tests (340 unit + 12 integration + 1 doc-test)
  with shared test utilities
