## Motivation and Context
The three conformance tasks were named `conformance`, `conformance_list`, and `conformance_server`,
spelling out with underscores the grouping that Rake expresses with namespaces.
They are now `conformance:test`, `conformance:list`, and `conformance:server`.
The bare `conformance` task is kept as an alias for `conformance:test`.
## How Has This Been Tested?
By running `rake -T` to confirm the three tasks are grouped under `conformance:`
with the alias listed beside them, `rake --dry-run default` to confirm that the default task
resolves `conformance:test`, and `rake conformance:list` to exercise a renamed task end to end.
## Breaking Changes
None. These are development-only Rake tasks.
