v0.4.0

0.4.0

Features

• Add DuplicatePolicy.append so a normalized route slot can retain multiple
  handlers in registration order.
• Router.matchAll(...) now expands appended entries from the same slot while
  keeping deterministic route priority ordering.

Fixes

• matchAll(...) now snapshots captured params before backtracking so lazy
  parameter materialization stays stable for every collected match.
• Lookup normalization now rejects interior empty path segments such as
  "/users//42" instead of letting fallback wildcards match them.

Performance

• Reduced matcher hot-path overhead by removing recursive traversal and
  streamlining slot collection/materialization.
• Improved matchAll(...) throughput across static, dynamic, and appended-route
  scenarios with dedicated benchmarks.
