test: P0-G end-to-end smoke tests — WAL, checkpoint, hooks, GC, Cap'n Proto (P0-15a-e)
Add 5 E2E integration test files that cross sub-phase boundaries: - test_e2e_wal.c (P0-15a): WAL write+read-back (entry count), torn-write recovery via ftruncate + persist_recover(), chained-CRC corruption stops replay at last valid entry. - test_e2e_checkpoint.c (P0-15b): 20-entry WAL + checkpoint + 10 post- checkpoint entries + recover asserts current_lsn >= 30 and checkpoint_lsn > 0; WAL trim after two checkpoints; snap_keep_n rotation with 4 rounds. - test_e2e_hooks.c (P0-15c): persist_job_hook_fun(HOOK_DETAIL_JOB_NEW) writes WAL_JOB_SUBMIT entry; persist_worker_hook_fun(HOOK_DETAIL_WORKER_JOIN) writes WAL_WORKER_CTRL; 3-call sequence preserves monotone LSN order and verifies header LSN fields on disk. - test_e2e_gc.c (P0-15d): running job retained; expired finished job not retained; JOB_STAT_TRANSIENT times out; expired unavailable worker not retained; checkpoint-after-WAL integration smoke. - test_e2e_capnp.c (P0-15e): persist_config_t → capnp_persist_cfg_t 8-field round-trip; capnp_snap_hdr_t field values and struct size (48 bytes); capnp_repl_envelope_t fields including WAL_CRC_NONE sentinel. Total: 89 tests, 0 failures (was 72 before this commit).

/* P0-15e: Cap'n Proto partial merge semantics
|
||||
*
|
||||
* Verifies that the three persistence Cap'n Proto mapped types
|
||||
* (capnp_persist_cfg_t, capnp_snap_hdr_t, capnp_repl_envelope_t)
|
||||
* and the generated struct PersistConfig / SnapshotHeader / ReplEnvelope
|
||||
* round-trip through their C struct representations correctly.
|
||||
*
|
||||
* These are structural/compile-time + value round-trip tests that span
|
||||
* the Cap'n Proto schema generation (P0-C) and the typemap.h definitions.
