Purpose of change (The Why)

Add a sleep performance option that skips rendering-heavy sleep turns while preserving gameplay effects and a safety fallback when hostiles are nearby.

Describe the solution (The How)

• Added SLEEP_SKIP_TIME option (Skip Time When Sleeping) with requested description text.
• Added hostile-in-reality-bubble safety prompt and fallback to normal sleep flow.
• Added fast sleep-time progression path that advances turns without wait-popup rendering while still processing item/field/vehicle updates.
• Added tests for safe skip, hostile fallback behavior, and world progression effects (rot + charging).

Describe alternatives you've considered

• Full inline reimplementation of do_turn() during sleep skip; rejected due to instability/segfault risk in tests.

Testing

• cmake --build --preset linux-full --target astyle
• cmake --build --preset linux-full --target cataclysm-bn-tiles cata_test-tiles
• ./out/build/linux-full/tests/cata_test-tiles "[sleep][perf]"
• ./out/build/linux-full/tests/cata_test-tiles "Vehicle charging station"
