The post-merge valgrind job on dev hangs.  Root cause: the CI valgrind step
exports FASTSYNC_UNDER_VALGRIND=1, but nothing read it, and the
/proc/self/maps "vgpreload" probe is unreliable on valgrind 3.22 (the guest's
maps no longer list the tool's own libraries).  So the fork-based unit tests
ran under valgrind anyway; tests that call io_set_fds() left the thread-local
read/write descriptors pointing at a closed test pipe, and a later
send_n_data()/receive_n_data() call was silently redirected to those stale fds
(legacy_session() prefers the globals, which the stdin/stdout SSH server
requires).  Later tests only worked by fd-reuse luck; under valgrind the fd
numbers no longer coincide, so the read blocked forever on an empty pipe.

- test_utils.h: honor FASTSYNC_UNDER_VALGRIND (already set by ci.yaml) and keep
  the maps scan as a best-effort fallback.  Reset io_set_fds(-1, -1) at the
  start of every RUN_TEST so one suite cannot leak descriptor redirection into
  the next.
- test_iconv.c: skip the forking wire-string roundtrip under valgrind like the
  other fork-based tests.
- config.c: initialize per_dir_filter_count in config_set_defaults.  The field
  was never initialized, so -F/-FF counting read uninitialized heap (valgrind:
  conditional jump on uninitialised value at client_cli.c:1464) and could count
  from garbage.

Verified with the CI-equivalent command (FASTSYNC_UNDER_VALGRIND=1 valgrind
--leak-check=full --show-leak-kinds=definite --error-exitcode=1): completes
with 0 errors (previously hung >80 min).  Unit 43/43; full integration 729
passed; cppcheck and clang-format clean.

TapTap 2ec17e821c fix(daemon): harden bounded per-source registry races
Stamp host_last_use before publishing a bucket key and treat an unstamped
(last_use == 0) bucket as live, so a just-claimed bucket can no longer be
stolen by a concurrent reclaimer.

After a successful eviction CAS, re-scan for the interned key and, when an
earlier bucket already holds it, zero the duplicate's active count and
return the canonical bucket, preventing orphaned per-host counts and cap
overshoot under full-table concurrency.

Add a message-carrying EXPECT_FAIL primitive and use it for the daemon-conf
buffer-overflow guard, and add a fork-based test that records auth failures
from forked children and asserts the parent observes the shared lockout.
