Release v0.4.0

New Features

• Manifest scripts — packages can now run setup steps automatically at key moments during install and uninstall (lifecycle events). See
  docs/script.md.
• Local package sources — you can install packages from a local folder, not just from GitHub. Configure sources with the new /source
  options on init.
• New product command (replaces listproducts) — list your Delphi installations, or look up a specific one with product <name>. Use /detail to see all platform paths.
• status as the default command — just run blocks to see the current workspace status.

Improvements

• Cleaner uninstall — removing a package now also deletes the .bpl / .dcp files it produced, leaving no leftovers.
• Install history — Blocks now records when each package was installed.
• Better IDE setup — the blocks output folder is added to the IDE PATH during init, with priority over other entries.
• Smarter command options — options now accept aliases, plus numbers and predefined choices, making commands easier to use.
• More documentation — added a full CLI reference (docs/cli.md) along with guides on manifests, scripting, and versioning.

Bug Fixes

• Fixed the "Delphi is running" check so it correctly recognizes which profile is actually open.
