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)
