devel/jj: update to 0.10.0

[0.10.0] - 2023-10-04

### Breaking changes

* A default revset-alias function `trunk()` now exists. If you previously defined
  your own `trunk()` alias it will continue to overwrite the built-in one.
  Check [revsets.toml](cli/src/config/revsets.toml) and [revsets.md](docs/revsets.md)
  to understand how the function can be adapted.

### New features

* The `ancestors()` revset function now takes an optional `depth` argument
  to limit the depth of the ancestor set. For example, use `jj log -r
  'ancestors(@, 5)` to view the last 5 commits.

* Support for the Watchman filesystem monitor is now bundled by default. Set
  `core.fsmonitor = "watchman"` in your repo to enable.

* You can now configure the set of immutable commits via
  `revset-aliases.immutable_heads()`. For example, set it to
  `"remote_branches() | tags()"` to prevent rewriting those those. Their
  ancestors are implicitly also immutable.

* `jj op log` now supports `--no-graph`.

* Templates now support an additional escape: `\0`. This will output a literal
  null byte. This may be useful for e.g.
  `jj log -T 'description ++ "\0"' --no-graph` to output descriptions only, but
  be able to tell where the boundaries are

* jj now bundles a TUI tool to use as the default diff and merge editors. (The
  previous default was `meld`.)

* `jj split` supports the `--interactive` flag. (This is already the default if
  no paths are provided.)

* `jj commit` accepts an optional list of paths indicating a subset of files to
  include in the first commit

* `jj commit` accepts the `--interactive` flag.

[0.9.0] - 2023-09-06

### Breaking changes

* The minimum supported Rust version (MSRV) is now 1.71.0.

* The storage format of branches, tags, and git refs has changed. Newly-stored
  repository data will no longer be loadable by older binaries.

* The `:` revset operator is deprecated. Use `::` instead. We plan to delete the
  `:` form in jj 0.15+.

* The `--allow-large-revsets` flag for `jj rebase` and `jj new` was replaced by
  a `all:` before the revset. For example, use `jj rebase -d 'all:foo-'`
  instead of `jj rebase --allow-large-revsets -d 'foo-'`.

* The `--allow-large-revsets` flag for `jj rebase` and `jj new` can no longer be
  used for allowing duplicate destinations. Include the potential duplicates
  in a single expression instead (e.g. `jj new 'all:x|y'`).

* The `push.branch-prefix` option was renamed to `git.push-branch-prefix`.

* The default editor on Windows is now `Notepad` instead of `pico`.

* `jj` will fail attempts to snapshot new files larger than 1MiB by default.
  This behavior can be customized with the `snapshot.max-new-file-size`
  config option.

* Author and committer signatures now use empty strings to represent unset
  names and email addresses. The `author`/`committer` template keywords and
  methods also return empty strings.
  Older binaries may not warn user when attempting to `git push` commits
  with such signatures.

* In revsets, the working-copy or remote symbols (such as `@`, `workspace_id@`,
  and `branch@remote`) can no longer be quoted as a unit. If a workspace or
  branch name contains whitespace, quote the name like `"branch name"@remote`.
  Also, these symbols will not be resolved as revset aliases or function
  parameters. For example, `author(foo@)` is now an error, and the revset alias
  `'revset-aliases.foo@' = '@'` will be failed to parse.

* The `root` revset symbol has been converted to function `root()`.

* The `..x` revset is now evaluated to `root()..x`, which means the root commit
  is no longer included.

* `jj git push` will now push all branches in the range `remote_branches()..@`
  instead of only branches pointing to `@` or `@-`.

* It's no longer allowed to create a Git remote named "git". Use `jj git remote
  rename` to rename the existing remote.
  [#1690](https://github.com/martinvonz/jj/issues/1690)

* Revset expression like `origin/main` will no longer resolve to a
  remote-tracking branch. Use `main@origin` instead.

### New features

* Default template for `jj log` now does not show irrelevant information
  (timestamp, empty, message placeholder etc.) about the root commit.

* Commit templates now support the `root` keyword, which is `true` for the root
  commit and `false` for every other commit.

* `jj init --git-repo` now works with bare repositories.

* `jj config edit --user` and `jj config set --user` will now pick a default
  config location if no existing file is found, potentially creating parent
  directories.

* `jj log` output is now topologically grouped.
  [#242](https://github.com/martinvonz/jj/issues/242)

* `jj git clone` now supports the `--colocate` flag to create the git repo
  in the same directory as the jj repo.

* `jj restore` gained a new option `--changes-in` to restore files
  from a merge revision's parents. This undoes the changes that `jj diff -r`
  would show.

* `jj diff`/`log` now supports `--tool <name>` option to generate diffs by
  external program. For configuration, see [the documentation](docs/config.md).
  [#1886](https://github.com/martinvonz/jj/issues/1886)

* A new experimental diff editor `meld-3` is introduced that sets up Meld to
  allow you to see both sides of the original diff while editing. This can be
  used with `jj split`, `jj move -i`, etc.

* `jj log`/`obslog`/`op log` now supports `--limit N` option to show the first
  `N` entries.

* Added the `ui.paginate` option to enable/disable pager usage in commands

* `jj checkout`/`jj describe`/`jj commit`/`jj new`/`jj squash` can take repeated
  `-m/--message` arguments. Each passed message will be combined into paragraphs
  (separated by a blank line)

* It is now possible to set a default description using the new
  `ui.default-description` option, to use when describing changes with an empty
  description.

* `jj split` will now leave the description empty on the second part if the
  description was empty on the input commit.

* `branches()`/`remote_branches()`/`author()`/`committer()`/`description()`
  revsets now support exact matching. For example, `branch(exact:main)`
  selects the branch named "main", but not "maint". `description(exact:"")`
  selects commits whose description is empty.

* Revsets gained a new function `mine()` that aliases `author(exact:"your_email")`.

* Added support for `::` and `..` revset operators with both left and right
  operands omitted. These expressions are equivalent to `all()` and `~root()`
  respectively.

* `jj log` timestamp format now accepts `.utc()` to convert a timestamp to UTC.

* templates now support additional string methods `.starts_with(x)`, `.ends_with(x)`
  `.remove_prefix(x)`, `.remove_suffix(x)`, and `.substr(start, end)`.

* `jj next` and `jj prev` are added, these allow you to traverse the history
  in a linear style. For people coming from Sapling and `git-branchles`
  see [#2126](https://github.com/martinvonz/jj/issues/2126) for
  further pending improvements.

* `jj diff --stat` has been implemented. It shows a histogram of the changes,
  same as `git diff --stat`. Fixes [#2066](https://github.com/martinvonz/jj/issues/2066)

* `jj git fetch --all-remotes` has been implemented. It fetches all remotes
  instead of just the default remote

### Fixed bugs

* Fix issues related to .gitignore handling of untracked directories
  [#2051](https://github.com/martinvonz/jj/issues/2051).

* `jj config set --user` and `jj config edit --user` can now be used outside of
  any repository.

* SSH authentication could hang when ssh-agent couldn't be reached
  [#1970](https://github.com/martinvonz/jj/issues/1970)

* SSH authentication can now use ed25519 and ed25519-sk keys. They still need
  to be password-less.

* Git repository managed by the repo tool can now be detected as a "colocated"
  repository.
