fix(hook): harden detour install, unload, and delta reconnection

Initialize every detour before enabling any, so a hook body that calls
another detour's trampoline can never hit an uninitialized detour and abort
the process. Pin the module on load so unloading can no longer leave
kernel32/ntdll patched to jump into freed memory. On a failed FILETIME
conversion, fall through to the real time instead of returning an
uninitialized SYSTEMTIME. Reconnect the shared delta mapping lazily so
setting a delta after injection takes effect instead of being disabled
forever. Add host-agnostic tick-conversion tests.

+# time-mocker-target
+
+Java test target for [time-mocker](https://github.com/tiennm99/time-mocker) — validates injected fake time behavior.
+
+## Quick start
+
+```bash
+./gradlew run
+```
+
+Run alongside `time-mocker` to verify that system time injection works correctly.
+
+## Expected behavior
+
+**Without time-mocker** — prints actual current time, ticking every second:
+
+```
+2025-01-15T08:30:01
+2025-01-15T08:30:02
+2025-01-15T08:30:03
+```
+
+**With time-mocker injecting a fake date** (e.g. 2000-06-15T12:00:00) — the same binary prints the mocked time instead:
+
+```
+2000-06-15T12:00:01
+2000-06-15T12:00:02
+2000-06-15T12:00:03
+```
+
+If the output reflects the injected date rather than real system time, the injection is working correctly.
