…lidator The validator previously only discovered sharding rules via `op_single_dim_strategy_funcs` and `op_strategy_funcs`. This adds a third fallback path that uses `DecompShardingStrategy` to discover rules for ops that have decompositions but no direct strategy registration. Extracts a shared `_extract_rules_from_op_strategy` helper to avoid duplicating the normalize/filter logic between the `op_strategy_funcs` and decomp paths. Authored with Claude. [ghstack-poisoned]

The validator previously only discovered sharding rules via
op_single_dim_strategy_funcsandop_strategy_funcs. This adds athird fallback path that uses
DecompShardingStrategyto discover rulesfor ops that have decompositions but no direct strategy registration.
Extracts a shared
