SaveKit - Roblox Player Data Saving

Player data that doesn't get lost. Drop SaveKit in ServerScriptService, set your starting data, and press Play.

• Session locking: quick server hops can't overwrite new progress with old progress
• Crash recovery: a crashed server's lock expires, so players can always get back in
• No silent resets: if data can't load, the player is asked to rejoin instead of starting from zero
• Saves on leave, on a timer and on shutdown
• Leaderstats are created and saved automatically, even when other scripts change them (works with ShopKit and RewardsKit)
• New Template keys reach existing players automatically
• A simple API: Get, Set, Increment, Save, OnLoaded
• Clean, commented code with no obfuscation and no remote loading

Includes SaveKit.rbxmx (Insert from File), the plain .lua sources for Rojo, and a README.

The code was written with an AI assistant and covered by automated tests.
