increase CI heap so the binary-compatibility check does not run out of
memory (#654)
Motivation:
The `Check Code Style` job, which runs `checkCodeStyle;
mimaReportBinaryIssues`,
fails with `java.lang.OutOfMemoryError: Java heap space`. sbt runs with its
default 1g heap and spends most of the job in GC before dying:
[warn] In the last 10 seconds, 24.282 (253.1%) were spent in GC.
[Heap: 0.00GB free of 1.00GB, max 1.00GB]
java.lang.OutOfMemoryError: Java heap space
[error] [launcher] error during sbt launcher: java.lang.OutOfMemoryError
The unscoped `mimaReportBinaryIssues` loads current and previous classfiles
for
every module in one JVM, so it is the peak consumer. This is not specific
to any
one PR - `main` has failed the same way on every run since #652.
Modification:
Set `JAVA_OPTS: "-Xmx4g"` in the workflow-level `env` block of the CI
workflow,
so every job in it gets a 4g heap. 4g matches what this repository already
uses
for its other heavy sbt jobs (`link-validator.yml`, `publish-*-docs.yml`),
and
is well inside the memory available on the GitHub-hosted runners.
This is deliberately confined to the CI workflow rather than `.sbtopts`, so
local sbt runs keep whatever heap the developer has configured.
Result:
The binary-compatibility check completes instead of exhausting the heap,
and the
`Check / Binary Compatibility` job can pass again.
Tests:
- Not run - CI configuration only; the change is verified by the CI run on
this
PR, which is the job that was failing.

Refs #653 - that PR is blocked by this same pre-existing failure
