fix: prevent mineral and squad infinite loops

This fix addresses two critical infinite loop issues that waste CPU:

1. Mineral Creep Infinite Loop
----------------------------
Mineral creeps would infinitely loop trying to transfer resources from
the terminal when insufficient amounts (1-4 units) were available.

Changes:
- Update validation threshold from === 0 to < LAB_REACTION_AMOUNT (5)
  in both setStatePrepareReactionLab1WithResource and
  setStatePrepareReactionLab2WithResource to match room cleanup logic
- Add reaction cleanup in handleWithdrawFromSource to delete
  room.memory.reaction when resources are insufficient, preventing
  immediate re-setting of the same failed state
- Enhance validation check to also verify resource amount meets
  LAB_REACTION_AMOUNT threshold during withdrawal

2. Squad Bouncing at Room Borders
--------------------------------
Squad creeps (both siege and heal) would bounce infinitely between
room exits, logging "Reached end of handling() why?" every tick.

Root cause: When creeps reached target room border, they would:
- Enter target room -> set routing.reached = true
- Move back across border due to border tile instability
- Delete routing.reached flag (not in target room anymore)
- Routing system restarts -> creep moves forward again
- Infinite loop continues

Changes:
- Add explicit if/else logic in squadsiege.action to separate
  traveling vs in-target-room behavior
- Add border protection: only reset routing.reached if not at border
  tile (using isBorder check) to prevent bouncing
- Don't execute siege() when traveling (not in target room)
- Apply same fix to squadheal.action for consistency

Both fixes ensure consistent validation across code paths and make
the systems self-healing by clearing invalid states immediately.
