Unit test (test_pcl26j_free): exercises all four fixed call sites —
psync_request_range_t, synced_down_folder, folder_tasks_t, and
psync_sector_inlog_t — using --wrap=malloc/free to verify that
pmem_free() passes the header pointer to free(), not the data pointer.
Includes a harness self-check that confirms bare free(data_ptr) is
detected. Would have failed against pre-fix code.
Smoke test (smoke-test-large-read.sh): builds pcloudcc with ASAN,
starts the daemon, streams a large file (>=50 MB) from the FUSE mount
to /dev/null to force multi-range psync_request_range_t allocation and
teardown via psync_pagecache_free_request, then scans the ASAN log for
any bad-free reports.
