⚡ Bolt: Optimize _fallback_state_from_partial_dps overhead

[damacus]

💡 What: Replaced a set comprehension and an .intersection() call with an early-returning .isdisjoint() check and a short-circuiting for loop in _fallback_state_from_partial_dps.
🎯 Why: _fallback_state_from_partial_dps is called on the hot path during state updates. The previous implementation allocated a new set (via set comprehension) and then created another set using .intersection(). These operations triggered unnecessary O(N) memory allocations and garbage collection cycles on every evaluation.
📊 Impact: Reduces memory allocations from O(N) to O(1) in the early-exit path, and prevents creating new sets in memory, improving CPU efficiency on the hot path.
🔬 Measurement: Verify using Python performance profiling tools. The logic was verified using a standalone standalone script to confirm that the output matches the original implementation.

Pull request overview

This PR targets performance on the vacuum entity hot path by optimizing _fallback_state_from_partial_dps to avoid unnecessary set allocations and allow earlier short-circuiting, while also cleaning up unused imports across tests and a few modules.

Changes:

• Optimized _fallback_state_from_partial_dps to avoid set allocations and short-circuit sooner during state inference.
• Removed unused imports across the test suite (and a few runtime modules) to reduce lint noise / dead code.
• Minor import cleanup in helper scripts used for DPS analysis.
