puff 1.0.0

Added

• Support for managing entire directories as first-class units — puff add config/ moves the
  directory to puff's data store and replaces it with a single directory symlink
• --dir flag on add command to create a fresh managed directory that doesn't exist yet
• Auto-detection of files vs directories when running puff add on existing paths
• Auto-absorb: puff add config/ silently merges individually managed files already inside
  config/ into the directory
• puff forget and puff forget --delete work on managed directories
• Guards that prevent adding/forgetting individual files inside a managed directory
• puff init, puff link, and puff project forget handle managed directories correctly
  (directory symlinks, backup of conflicting real directories, recursive restore)
• Support for managing files located in subdirectories of a project
• --version flag to print the version number with commit hash
• status command to print whether current directory is a part of puff-managed project and list
  managed files if it is
• completions command to generate shell completions (dynamic, with project name completion for
  link and project forget)
• support multiple files provided to add and forget commands
• a cd command that spawns subshell at the puff's projects directory - user can backup the files
• link command to create bring puff-managed files into other directories than the main project directory (useful for git
• modernize commands that require user input (such as puff init) with better UX
  worktrees, jj workspaces, or any secondary working copy)
• e2e tests

Changed

• puff status now shows "Managed items:" (was "Managed files:") with directories displayed
  with a trailing /
• puff link now reports "item(s)" instead of "file(s)"
• Renamed rm command to forget
• Renamed project rm command to project forget
• Updated all dependencies; migrated to Rust 2024 edition
• Improved error messages
• Fixed puff add printing a false success message when a file exists in both the project
  directory and puff's registry (conflict now properly errors out)
• projects are now stored in XDG_DATA_HOME/puff/projects instead of XDG_CONFIG_HOME/puff/configs

Removed

• Removed symlink crate dependency in favor of the standard library
