Add protect/storage lists, dynamic trash thresholds, tie resolution

Protect & storage lists:
- protect.csv: unlocked garage cars (state != 0, locked == false) worth
  locking more copies of. Needed copies = best configs surviving the
  RQ-band thresholds (prize cars and RQ >= 80 always count); already
  locked copies (copy_count) are subtracted, surplus drops off the list.
- storage.csv: Keep/Trash recommendation for storage cars (state == 0)
  using the same copy-count logic; surplus unlocked copies are fusion
  material.
- user_data.rs now parses card state (garage vs storage), garage slots
  (user.garageSlots/garageSlotsUsed), and unlocked card maps.

Dynamic trash thresholds:
- TrashThresholds derive RQ 20-29/30-39 as half/a quarter of a base
  value (--trash-base-count, default 4); RQ 40+ never covered.
- plan_trash_rules escalates the base automatically while projected free
  garage slots (capacity - used + unlocked non-best copies + new trash
  candidates, copies counted per card) stay below --garage-min-free
  (default 20), stopping when no further cars qualify. Effective
  thresholds and projection are printed.
- Improve-based low-value cars (best target count at or below the band
  threshold) land in trash.csv; collect_improve_entries is shared with
  improve.csv and computed once per run.

Same-car tie resolution:
- resolve_tied_configs collapses tie-equivalent configs of the same car
  per track (compute_car_counts, write_details_csv), preferring the
  player's owned final-build config. Fixes phantom rows like the
  Mercedes 280 SL 332 entry tied at 61.31 by its owned 323, inflated
  per-config track counts, and pointless second-copy recommendations.

Wishlist:
- Prize cars are excluded from the ideal wishlist and surface in
  remove.csv via the ideal-set difference.

CLI: new protect command; --trash-base-count/--garage-min-free on
trash/protect/all; details command reuses counts for tie resolution.
README updated for all new files, flags, and criteria.
