Merge branch 'working' into job_peek_lchen

job_peek_lchen: Add fetchfile feature (job output/error peek proxy)
working: HA/Raft infrastructure (consensus, replication, config mgmt)

Conflict resolution summary:
- controller.capnp: fetchfile @41, fetchfilereply @18, fetchfilemsg @30
- cluster.c: bifurcated OPCode_reply for fetchfile + config-push ACK
- job.c: kept full fetchfile pending-request subsystem (~183 lines)
- request.c: kept both xce_fetchfile_req() and XCE_RETRY_DEFAULTS
- helper.c: added missing preVoteRequest/preVoteReply mappings
- All 15 new test registrations (test_cbuf.c + 14 HA tests)
