Log Message:
jj: update to 0.24.0.

## [0.24.0] - 2024-12-04

### Breaking changes

* `jj move` has been removed. It was deprecated in 0.16.0.

* `jj checkout` and the built-in alias `jj co` have been removed.
  It was deprecated in 0.14.0.

* `jj merge` has been removed. It was deprecated in 0.14.0.

* `jj git push` no longer pushes new bookmarks by default. Use `--allow-new` to
  bypass this restriction.

* Lines prefixed with "JJ:" in commit descriptions and in sparse \ 
patterns (from
  `jj sparse edit`) are now stripped even if they are not immediately followed
  by a space. [#5004](https://github.com/martinvonz/jj/issues/5004)

### Deprecations

### New features

* Templates now support the `==` and `!=` logical operators for `Boolean`,
  `Integer`, and `String` types.

* New command `jj absorb` that moves changes to stack of mutable revisions.

* New command `jj util exec` that can be used for arbitrary aliases.

* `jj rebase -b` can now be used with the `--insert-after` and `--insert-before`
  options, like `jj rebase -r` and `jj rebase -s`.

* A preview of improved shell completions was added. Please refer to the
  \ 
[documentation](https://martinvonz.github.io/jj/latest/install-and-setup/#command-line-completion)
  to activate them. They additionally complete context-dependent, dynamic values
  like bookmarks, aliases, revisions, operations and files.

* Added the config setting `snapshot.auto-update-stale` for automatically
  running `jj workspace update-stale` when applicable.

* `jj duplicate` now accepts `--destination`, `--insert-after` and
  `--insert-before` options to customize the location of the duplicated
  revisions.

* `jj log` now displays the working-copy branch first.

* New `fork_point()` revset function can be used to obtain the fork point
  of multiple commits.

* The `tags()` revset function now takes an optional `pattern` argument,
  mirroring that of `bookmarks()`.

* Several commands now support `-f/-t` shorthands for `--from/--to`:
  - `diff`
  - `diffedit`
  - `interdiff`
  - `op diff`
  - `restore`

* New `ui.conflict-marker-style` config option to change how conflicts are
  materialized in the working copy. The default option ("diff") renders
  conflicts as a snapshot with a list of diffs to apply to the snapshot.
  The new "snapshot" option renders conflicts as a series of \ 
snapshots, showing
  each side and base of the conflict. The new "git" option replicates Git's
  "diff3" conflict style, meaning it is more likely to work with \ 
external tools,
  but it doesn't support conflicts with more than 2 sides.

* New `merge-tools.<TOOL>.conflict-marker-style` config option to override the
  conflict marker style used for a specific merge tool.

* New `merge-tools.<TOOL>.merge-conflict-exit-codes` config option to allow a
  merge tool to exit with a non-zero code to indicate that not all conflicts
  were resolved.

* `jj simplify-parents` now supports configuring the default revset when no
   `--source` or `--revisions` arguments are provided with the
   `revsets.simplify-parents` config.

### Fixed bugs

* `jj config unset <TABLE-NAME>` no longer removes a table (such as `[ui]`.)
