Align bare-int array-init assignability to Hare's literal-fits rule (ref/harec/src/types.c promote_flexible): accept untyped-int array elements that FIT the element type, reject out-of-range loud. cstage (rejected all bare-int arrays, over-strict) and wwstage (accepted + silently truncated out-of-range, over-loose) converge to the same accept-if-fits rule. Per-element: foldable int literal range-checked against element type [min,max] via def_cast_fits (rule-13 type-table widths); non-foldable element falls back to type_assignable. cstage: new arrlit_init_fits, N_LET decl-check fallback after whole- array type_assignable fails. wwstage: checkletassign array branch + route top-level lets through checkletassign (were unchecked — only function-body lets ran assignability; closes #146 wwstage str->u8 over-accept). Scalar-init range-check (let X:u8=300 truncates, both stages, pre-existing) deferred to #148 — language-wide, needs bootstrap audit + explicit-cast conversion. def-array accept-if-fits deferred to #151 (def constfold machinery, different risk). Both bootstrap-NEUTRAL. Test 920 (14 rows — accept: in-range u8/u32/u64/i32 + u8/i8 boundary + typed regression + non-foldable-body; reject: over-range + over-256 + i8-over + neg-for-unsigned + str->u8 + non-foldable-wider). Non- foldable else-branch cs==ww verified (matching-type accept + byte-id; wider-runtime-int reject both stages). Make test: 183/183 incl 990-997 byte-id + combined_ww_fresh.
