0.5.0-alpha

Changed

• Major simplification: core folder-lock logic consolidated from scattered lib/ modules into main.lua; only util/folderlock_hasher, util/folderlock_updater, and util/folderlock_version remain as helpers
• Long-press menu labels simplified: unlocked folder → Lock folder, locked folder → Remove Lock
• Lock/unlock flow is now available only through the long-press context menu; the main Folder Lock menu shows About and updater/version entries

Removed

• Cover Cache Isolation feature and lib/folderlock_cache_isolation module
• folderlock_guard module; folder navigation and file-open interception now live directly in main.lua
• Main-menu Lock current folder / Unlock current folder entries

Fixed

• Updated unit and end-to-end tests to match the simplified architecture
