v1.5.0

What's Changed

Refactor

• Slice field constructors (Bytes, Ints64, Floats64, etc.) now eagerly copy
  the backing array and delegate to Const* counterparts
• Any() handles Snapshotter interface directly in the constructor
• Removed snapshotField and all snapshotRaw* helpers
• Consolidated small files: entrywriter.go → entry.go,
  jsonencoderconfig.go → jsonencoder.go, mutablelevel.go → level.go,
  noescape.go → time.go

CI & Dependencies

• Replaced Travis CI with GitHub Actions (matrix Go 1.22 + 1.23, golangci-lint)
• Bumped minimum Go version to 1.21
• Updated testify to v1.11.1

Tests

• Fixed race condition in newLoggerID
• Added test cases for Strings, Stringer, Formatter, nil error, non-Const slices
• Fixed all golangci-lint warnings (errcheck, staticcheck)
