Logging: per-session file and debug-gated verbose logs

- Open /tmp/hl2hake.log once in the library constructor with "w" so each
  session starts clean, use line buffering, flush each line, and close it via
  atexit. No more fopen/fclose per message.
- Add logd() for verbose diagnostics, enabled only with HL2H_DEBUG=1.
- Move ESP/NPC scans, item-prop/item-classification logs, aimbot/silent-aim/
  melee/triggerbot/spread details, jumpbug tracking, bone dumps, netvar dumps,
  cmd-modified and ground-trace noise to logd().
- Keep logf() for lifecycle, config, warnings/errors, GUI open/close, item
  category/tagging summaries and item-crate detections so crate debugging
  works without the ESP stream.
- Supply crates now respect the max-distance slider (user change), with the
  stale comment and CONTEXT updated.
- Document HL2H_DEBUG=1 in play.sh and CONTEXT.

+## Logging

+- `/tmp/hl2hake.log` is opened once at startup with `"w"` (so it only contains
+  the current session), line-buffered, and closed via `atexit`.
+- `logf` is always on: lifecycle, warnings/errors, config, GUI open/close and
+  item-crate detections.
+- `logd` is off unless `HL2H_DEBUG=1`; it carries per-scan ESP/NPC/item-prop,
+  aimbot-target, bone and netvar noise. Run `HL2H_DEBUG=1 ./play.sh` to enable.
