Henrik Brodin 09f2980ff9 Add optional tmpfs storage for fuzzing corpus (#461 )

* Add optional tmpfs storage for fuzzing corpus

Add support for storing the node-local fuzzing corpus in tmpfs (RAM-based
filesystem) for improved I/O performance during fuzzing operations.

Key changes:
- Add CORPUS_TMPFS_PATH environment variable to configure tmpfs location
- Add cross-filesystem safe operations (copy+delete fallback for EXDEV)
- Update Corpus class to use tmpfs path when enabled while maintaining
  correct remote path calculation for rsync synchronization
- Add Helm chart configuration using /dev/shm (requires no host setup)
- Update fuzzer-bot, coverage-bot, merger-bot, seed-gen deployments

The feature is disabled by default. Enable by setting
global.volumes.corpusTmpfs.enabled=true in values.yaml.

Uses hostPath to /dev/shm/buttercup-corpus which is available on
Linux systems without requiring any Kubernetes host configuration.
