What this changes

GitCraft now asks before anything that throws work away for good, and says what will be lost:

• Hard reset from the graph: "Hard reset main to 1a2b3c4, throwing away every uncommitted change?"
• Deleting a branch asks only when no other branch, remote branch or tag has all of its commits ("Delete topic and the 1 commit on no other branch or tag?"). A branch that is merged anywhere, or pushed, goes without a question, also when it is not merged into the current branch (where git branch -d would refuse).
• Force push: when the current branch went its own way since the last push (ahead and behind, after an amend or a rebase), Push offers to force push with a lease, so commits someone else pushed since the last fetch are never overwritten.
• Dropping a stash asks first too.

This is the first item under "Next" in the roadmap; the README no longer warns about hard resets.

How it is tested

• Core (crates/core/tests/repo.rs): counting the commits only a branch has (tags, remote branches and a branch with a similar name keep them), deleting such a branch, and a force push after an amend that goes through, plus one the lease refuses after someone else pushed.

• App (crates/app/src/tests.rs), through right-click menus and the toolbar like a user: hard reset (cancel keeps the work, Reset discards it), deleting a merged and an unmerged branch, force pushing a diverged branch to a real remote, and dropping a stash.

• stage_and_commit_a_change now waits for a reload the watcher may start right after opening, as the other tests do (it tripped over that once on macOS here).

• Tried in the app on Linux: each question shows, Cancel and Escape leave everything as it was, and going ahead does what it says.

• cargo fmt --all, cargo clippy --workspace --all-targets -- -D warnings and cargo test --workspace pass

• It adds as little code as the change needs, and removes what it makes unnecessary

• Nothing in it comes from GitKraken or another closed-source client (see CONTRIBUTING.md)
