chore(hypatia): exempt vendored absolute-zero Java/Kotlin demos (#71)

## Summary

Adds 4 absolute-zero/examples/{java,kotlin}/ entries to
`.hypatia-ignore`, exempting the vendored language-demonstration files
that the new `governance-reusable.yml` (standards#168) now flags via its
language-policy step.

Same rationale as the existing `.res` / `.go` entries — these are
language-demonstration scaffolds, not load-bearing code. They mirror
files in the standalone `absolute-zero` repo's own example tree.

## Why

Dependabot rust-toolchain bump #69 has been red on `governance /
Language / package anti-pattern policy` since standards#168 merged. The
failure surfaces `absolute-zero/examples/java/Nop.java`,
`absolute-zero/examples/java/BalancedOps.java`,
`absolute-zero/examples/kotlin/Nop.kt`, and
`absolute-zero/examples/kotlin/BalancedOps.kt` — all vendored
demonstration files.

## Follow-up

Once standards#180 (file_pattern glob matching in `in_baseline()`)
merges, this whole `.hypatia-ignore` can collapse to one
`absolute-zero/examples/**` `file_pattern` entry in
`.hypatia-baseline.json`. Filed as a known follow-up.

## Test plan

- [ ] CI: governance/Language-policy step passes (with 9 exempt entries
now visible in the run log instead of 5 violations)
- [ ] Dependabot #69 unblocked once this merges
