* Add unit test for psync_task_free refcount fix (#377)
Adds tests/unit-tests/test_ptask_free.c to verify all code paths of the
psync_task_free fix from #377: single-owner free, last-ref destroy,
non-last-ref decrement, READY task signaling, and lock-before-refcnt
ordering. All 5 tests pass. Also adds compiled binary to .gitignore.

* Add GitHub Actions CI workflow for unit tests
Triggers on push/PR to automated-testing branch. Installs cmake and
build-essential, builds all test targets via cmake, and runs ctest
--output-on-failure. Fails workflow on any test failure.

* Replace cmake CI with make tests/check targets
Adds tests and check targets to Makefile — no cmake required.
Each test binary is built with the correct flags (pthread, -lrt,
--wrap linker flags for prun/ptools_errptr). CI workflow installs
only build-essential, runs make tests then make check; exits non-zero
on any failure. All 8 test suites pass locally.

* Fix CI: install libfuse3-dev so Makefile parses on Ubuntu
detect_fuse.sh runs at Makefile parse time; without fuse headers the
$(error) fires before any target runs. Adding libfuse3-dev unblocks
make tests (test binaries themselves don't link fuse).

* Fix pcl-dls.1: free errPtr between calls in ptools_set_backend_file_dates()
char *errPtr was already used instead of char msgErr[1024], but was
not freed between the two ptools_backend_call() invocations. If the
first call allocated errPtr, the second would overwrite the pointer
without freeing it. Add free(errPtr); errPtr = NULL; between the two
calls to eliminate the leak.
Ref GH #194.

* Add ptools_set_backend_file_dates() errPtr lifecycle tests (pcl-dls)
6 test cases using malloc/free wrapping covering both-succeed,
call1-error, call2-error, both-errors, pre-fix leak demonstration,
and no-double-free after mid-free NULLing.

* Fix pcl-aex.1: validate PCLOUD_LOG_PATH before use in psync_debug_path()
Add pdbg_path_is_safe() helper that rejects PCLOUD_LOG_PATH values
that are not absolute, contain '..' path components, or do not resolve
under the user HOME directory or /tmp. On rejection, fall back to the
default ~/.pcloud/debug.log path and emit a warning to stderr.
Also fix a pre-existing memory leak: ppath_home() return was not freed
in the default-path branch.
Ref GH #291.

* Add PCLOUD_LOG_PATH path-safety tests (pcl-aex)
28 test cases covering relative paths, '..' traversal, paths outside
HOME and /tmp, valid accepted paths, and psync_debug_path() env
fallback behaviour.

* Fix pcl-aqb.1: eliminate function-pointer cast UB in start_thread() via union
Replace the single void* run field in thread_data with a union
{ thread0_run run0; thread1_run run1 } so each function pointer is
stored and retrieved at its correct type, eliminating the
thread0_run <-> thread1_run cast chain UB. Split start_thread() into
prun_thread() and prun_thread1() that each populate the appropriate
union member, backed by a shared start_thread_common() helper. Add
malloc NULL check with error log in both public functions.
pthread_create failure handling (log + free) was already present.
Ref GH #199.

* Add prun start_thread() resource-leak and UB tests (pcl-aqb)
8 test cases using linker interposition covering pthread_create
failure data-free, attr_destroy on failure, malloc failure graceful
return, union fn storage without cast, and success path accounting.

* Fix pcl-a1j.1: replace sprintf with snprintf and add strcat length check in ptools_create_backend_event()
Add paramname length check (> 254 bytes → skip with warning) before
snprintf into charBuff[i][258], and validate the snprintf return
value. Add explicit length check before strcat into keyParams to
prevent overflow when paramname exceeds remaining buffer space.
Eliminates buffer overflow from long paramname.
Ref GH #195.

* Fix pcl-a1j.1: clamp pCnt to PTOOLS_MAX_PARAMS to prevent charBuff stack overflow
charBuff[30][258] is a fixed-size stack array but pCnt was unbounded,
allowing any caller with params->paramCnt > 30 to overflow the stack
via charBuff[i] access. Add PTOOLS_MAX_PARAMS (30) define, use it to
size charBuff, and clamp pCnt to PTOOLS_MAX_PARAMS with a warning log
before the loop.
Ref GH #195.

* Add ptools_create_backend_event() validation tests (pcl-a1j)
11 test cases covering pCnt clamping, paramname length guards,
snprintf boundary, keyParams overflow check, and comma-prefix
for subsequent params.

* Fix pcl-6nb.1: readResponse buffer over-read in rpcclient.cpp
Replace malloc'd receive buffer with stack array, fix the broken
validation (msg->length compared against POVERLAY_BUFSIZE rather
than max_value_size which excluded the header), fix the payload-read
loop target (msg->length already includes the header, so the old
`header_size + msg->length` limit over-read), add the missing
`msg->length > total_read` guard before memcpy, and add EINTR
handling in the read loop. Eliminates heap over-read when the daemon
sends msg->length > POVERLAY_BUFSIZE.
Ref GH #184.

* Add readResponse validation tests (pcl-6nb)
Six socketpair-based test cases covering oversized msg->length,
total_read underrun, header underflow, truncated header, valid
message, and exact-boundary acceptance.
