Filter literals were pushed to Lance in their natural Arrow type (every integer
Int64, every float Float64). Against a narrower indexed column DataFusion widens
to the literal's type and casts the COLUMN (`CAST(n32 AS Int64)`), which defeats
the scalar BTREE and degrades to a full filtered read. A physical-plan probe
confirms it: an Int32 column filtered by an i32 literal uses `ScalarIndexQuery`;
by an i64 literal it does not.
Thread the scan's `arrow_schema` through `build_lance_filter_expr` ->
`ir_filter_to_expr` and coerce each literal operand to the opposite column's
exact Arrow type, reusing `projection::literal_to_array` + `arrow_cast` (the same
path the in-memory arm uses, so the two arms agree). Coercion never demotes a
filter to None: on failure it falls back to the natural literal, because a node
scan has no in-memory fallback for inline filters.
