Copilot e3ef3a5b56 s3lifecycle: add lifecycle rule evaluator package

New package weed/s3api/s3lifecycle/ provides a pure-function lifecycle
rule evaluation engine. The evaluator accepts flattened Rule structs and
ObjectInfo metadata, and returns the appropriate Action.

Components:
- evaluator.go: Evaluate() for per-object actions with S3 priority
  ordering (delete marker > noncurrent version > current expiration),
  ShouldExpireNoncurrentVersion() with NewerNoncurrentVersions support,
  EvaluateMPUAbort() for multipart upload rules
- filter.go: prefix, tag, and size-based filter matching
- tags.go: ExtractTags() extracts S3 tags from filer Extended metadata,
  HasTagRules() for scan-time optimization
- version_time.go: GetVersionTimestamp() extracts timestamps from
  SeaweedFS version IDs (both old and new format)

Comprehensive test coverage: 54 tests covering all action types,
filter combinations, edge cases, and version ID formats.
