v3.43.0

• changed: git machete slide-out no longer requires the given branches to form a chain; literally any set of managed branches can be slid out at once, with each slid-out branch's surviving children reattached to (and, unless --no-rebase is passed, rebased/merged onto) that branch's nearest surviving ancestor
• changed: shell completion for git machete slide-out now suggests all managed branches (excluding the ones already given on the command line), rather than only those forming a valid chain
• deprecated: git machete list slidable (now equivalent to git machete list managed) and git machete list slidable-after, as git machete slide-out's shell completion no longer relies on either
• fixed: git machete status now renders [<worktree>] labels in repos whose linked worktrees are all in detached HEAD state, rather than treating the repo as single-worktree and suppressing every label
