lei.chen f2993d1efc fix(controller): trim config versions by ns mtime; unique test tmpdir 
Two pre-existing failures (2026-05-13, commit 491c255) surfaced by the
controller unit-test suite (1070 Tests 2 Failures), both in the config
version storage path:

1. conf_trim_old_versions sorted cluster.bin.* versions by
   second-granularity st_mtime. Versions saved within the same second
   (rapid replication, or the trim test's 15ms-spaced saves) tie, glibc's
   stable mergesort keeps creation order, and the newest (current-pointer)
   entry lands at the protected keep_n index — so nothing is pruned and
   keep_n+1 files remain. Store st_mtim (struct timespec) and compare
   tv_sec then tv_nsec.

2. cr_setup() built its tmpdir path from (pid, time(NULL)) at second
   granularity; a Unity assertion failure longjmps past cr_teardown(),
   leaking the dir, and the next test (same pid+second) silently inherited
   the leftover conf/current — cascading a second failure
   (test_conf_get_saved_tag_no_config read a real tag instead of 0). Add a
   per-invocation counter to the path so no two tests share a dir.

Verified: nix develop ./src --command bash src/tools/xce-build.sh all →
meson 9/9 Ok 0 Fail, controller 1070 Tests 0 Failures, xceadmin 172
passed, frontend Go all ok.
