Some.darker.night

Added a script module to the behavior pack manifest.
Implemented a rare false-positive system with:
distant footsteps behind/aside the player
ambient cave sound behind the player
very short-lived silhouette spawns that vanish almost immediately
Added role families to entities:
role_watcher
role_bait
role_chase
role_glitch
role_audio
Added script-side role tags on active entities for cleaner future logic.
Moved the heavy repeated behavior into script intervals:
chase maintenance
water bridging checks
sub anomaly processing
random structure processing
moonglitch timing
Reduced the old tick.json path to only the functions that still make sense every tick:
ban
cantsleep
safemode
Function optimization/fixes
Removed the old pattern where some objectives were being added from ticked functions.
Stopped running entities, entities_water, random_structure, SubAnomaly, and moonglitch from the main tick file.
Simplified fallback function files so they are lighter and less redundant.
Fixed the duplicate/random-structure mapping issue around the old structure roll logic while rebuilding it in script.
