XO1308: release build while a workspace overrides modules

An xo.work workspace builds the modules it uses from their local directories, overriding the versions xo.mod requires. That is for development only: a release build (xo build --release, and xo build --ci) must build exactly what xo.mod and xo.lock pin, so it fails while a workspace overrides a required module, naming those modules. Build with --workspace=off (or XO_WORK=off) to ignore xo.work, or release the overridden modules, require their new versions, and run xo mod tidy. See decision 0086.

Example

# xo.work: use ./api, use ./billing; api requires billing
xo build --release ./api

Fix

xo build --release --workspace=off ./api

Run xo explain XO1308 for this text in a terminal, or see section 10.6 of the specification.
