ASR-0004: Configurable key normalization

Context

Real-world configuration mixes kebab-case, snake_case, SCREAMING_SNAKE, and struct field names. Requiring mapstructure tags on every field is noisy.

Decision

After parsing and merging, codecs run internal/keymap.Walk with a Normalizer (default LowerAlnum: lowercase + strip non [a-z0-9]).
Callers may set WithKeyNormalizer(nil) to disable walking, or supply a custom function.

Consequences

POSIX env keys without - still align with YAML keys that contain hyphens once normalized.
CLI get applies the same normalizer to each path segment for consistency.

Status

Accepted — 2026-05-02.
