fix: say snapshots and simulators are deleted, not moved to the Trash

[bubleg]

The README and the app say nothing from storage cleanup is gone until the Trash is emptied, but unavailable simulators (simctl delete) and Time Machine local snapshots (tmutil deletelocalsnapshots) are deleted right away. Those items now say so in their notes, in clean (including --dry-run) and in the app's confirmation and result message, and the README is updated to match.

Review follow-up: with a simulator or snapshot selected, the app's button and dialog say Remove instead of Move to Trash, and clean leaves files macOS protects out of the amount it reports as moved.

Validation on macOS 27.0.1 (26A434), Apple silicon: swift build -c release, git diff --check and all 53 removemacai selftest checks pass. I checked the clean output and the new header in the app; there are no snapshots or unavailable simulators on my Mac, so I couldn't see the Remove dialog itself.

Summary by CodeRabbit

• Storage Cleanup
  • Cleanup details now distinguish files moved to the Trash from simulators and local Time Machine snapshots deleted immediately.
  • Confirmation messages warn when selected items will be permanently deleted and use wording that reflects the selected items.
  • Cleanup results report Trash movement and permanent deletions separately; permanent deletions are reported only when cleanup completes without problems.
  • Backup-disk backups remain untouched.

📝 Walkthrough

Walkthrough

Storage cleanup now distinguishes files moved to the Trash from simulators and snapshots deleted immediately. The Storage view and command-line confirmation describe permanent selections, and cleanup results report Trash moves separately from permanent deletions.

Changes

Storage cleanup

Layer / File(s)	Summary
Permanent item classification and disclosures Sources/removemacai/Storage.swift, README.md	StorageItem marks simulators and snapshots as permanent. The item descriptions and README state that they are deleted immediately rather than moved to the Trash.
Cleanup confirmation wording Sources/removemacai/App/Pages.swift, Sources/removemacai/TweakCommands.swift	The Storage view and command-line confirmation identify permanent selections and state that they are deleted immediately.
Cleanup result reporting Sources/removemacai/App/AppModel.swift, Sources/removemacai/TweakCommands.swift	Cleanup results report bytes moved to the Trash separately from permanent deletions. Permanent deletions are reported only when cleanup has no problems.

Merge Risk: 🟡 Moderate · up to b7aad

The confirmation dialog still presents an irreversible deletion of simulators or snapshots as a move to the Trash. The CLI can also overstate how much space the Trash will free when files are protected. Fix both before merging.

Change the confirmation title and button for permanent items.

When a simulator or snapshot is selected, the dialog still asks to move the selection to the Trash and offers a “Move to Trash” button. model.clean() deletes those items immediately. Use a title and button that describe removal when the selection contains a permanent item. Keep the Trash wording for files-only selections.

Update the confirmation dialog around `model.clean()` to show removal wording
when the selection contains a simulator or snapshot, while retaining the
existing Trash title and button for files-only selections.
