N_IDENT for a slice local now loads (AX=ptr, BX=len, CX=cap), matching the existing global-slice load. cgexpr learns N_SLICE: `base[lo:hi]` leaves the same triple in registers, so callers (return, arg push, reassignment) all share one shape. The let-init's pre-existing N_SLICE direct-store path stays as a specialisation; the new generic slice let-init catches fn-returning-slice and slice-ident initialisers. N_ASSIGN gains a TY_SLICE branch parallel to TY_STR: store all three halves to the local slot or, for globals, stash CX into DI before LEAQ-ing the address (CX is both the new cap and the address scratch).
