Validate FSST arrays without an execution context FSST validation only reads the last codes offset when the offsets are already a host-resident primitive array, so read it directly instead of executing a scalar with the hidden global `legacy_session()`. The constructors no longer need their `ExecutionCtx` and drop it.

Make Null take an execute kernel Null take executed its indices inside a reduce rule, which has no execution context, by reaching for the hidden global `legacy_session()`. Implement `TakeExecute` instead and register it on the session.

Validate RunEnd arrays without the legacy session `VTable::validate` has no execution context, so it now checks only the dtypes and lengths. The run-end bounds are checked with an explicit context by the constructors, as before, and by deserialization using its session.

Keep the session in ZstdBuffers for validity `ValidityVTable::validity` has no context, but a ZstdBuffers array has to rebuild its inner array to answer it. Keep the session the array was compressed or deserialized with instead of using the hidden global `legacy_session()`.

Format array values without the legacy session Display cannot receive an execution context, so build one from a default array session for each format call and reuse it across all rows instead of reaching for the hidden global `legacy_session()`.

Reduce Literal ScalarFnArray to ConstantArray Signed-off-by: Robert Kruszewski <github@robertk.io>

fix: avoid fill_null crashes on lazy fill values Execution now evaluates a fill that is not already a constant until it becomes one, then reads the scalar. The parent reduce and execute kernels return no match when the fill child is not constant, leaving that case to execution. A fill that is still not a scalar afterward still fails with the constant-or-scalar error. Tests cover a lazy literal fill and a varying fill that the kernels decline.

Inline collect_bool into the POPCNT RunEnd filter loop Give the POPCNT and portable rank loops distinct instantiations through a const parameter. With one caller per closure type LLVM inlines BitBuffer::collect_bool, so the hand-packed retain bitmap is no longer needed, and the inlined fill and SSE2 pack are about 10% faster on the run_end_filter benchmark.
