### What changes were proposed in this PR?
`ChannelConfig.generateChannelConfigs` previously used
`fromWorkerIds.zip(toWorkerIds)` for the `OneToOnePartition` arm, which
silently truncated to the shorter side and dropped surplus workers even though
the partition's
contract is a strict 1:1 pairing. This PR adds an
`assert(fromWorkerIds.size == toWorkerIds.size, ...)` precondition (mirroring
the `SinglePartition` arm in the same file) so mismatched inputs fail loudly
with a message that
names both sizes.
### Any related issues, documentation, or discussions?
Closes: #4799
### How was this PR tested?
The existing `ChannelConfigSpec` case that pinned the truncation behavior
is flipped to assert an `AssertionError` is raised in both asymmetric
directions (`from > to` and `to > from`). The equal-length, empty-input, and
other
partition arms are unchanged and still pass. Reproducer from the report
(`from=3, to=2`) now throws instead of returning a 2-element list.
