## Summary
This PR deprecates the `--isolated` flag. The treatment varies across
the APIs:
- For non-preview APIs, we warn but treat it as equivalent to
`--no-config`.
- For preview APIs, we warn and ignore it, with two exceptions...
- For `tool run` and `run` specifically, we don't even warn, because we
can't differentiate the command-specific `--isolated` from the global
`--isolated`.
I tweaked rooster to allow sections to be overridden from the CLI so we
can generate a separate preview changelog
See https://github.com/zanieb/rooster/pull/43 for the rooster changes
needed
I tested `./scripts/release.sh` as well.
