- `LegalizeOps` skips grouped `conv1d/2d/3d` when channel size is symbolic - The only blocker is `topi.nn.conv`'s divisibility `assert`s, which fail on symbolic `PrimExpr`; the grouped compute already handles symbolic dims ## How - Skip the divisibility check when the channel size is not a constant int - Remove the symbolic-channel guards from the conv legalize functions
