* Improve keymap errors from command typos
Currently, opening helix with a config containing a bad command mapping
fails with a cryptic error. For example, say we have a config (bad.toml)
with a command name that doesn't exist:
[keys.normal]
b = "buffer_close" # should be ":buffer-close"
When we `hx -c bad.toml`, we get...
> Bad config: data did not match any variant of untagged enum KeyTrie for key `keys.normal` at line 1 column 1
> Press <ENTER> to continue with default config
This is because of the way that Serde tries to deserialize untagged
enums such as `helix_term::keymap::KeyTrie`. From the Serde docs[^1]:
> Serde will try to match the data against each variant in order and the
> first one that deserializes successfully is the one returned.
`MappableCommand::deserialize` fails (returns an Err variant) when a
command does not exist. Serde interprets this as the `KeyTrie::Leaf`
variant failing to match and declares that the input data doesn't
"match any variant of untagged enum KeyTrie."
Luckily the variants of KeyTrie are orthogonal in structure: we can tell
them apart by the type hints from a `serde:🇩🇪:Visitor`. This change
uses a custom Deserialize implementation along with a Visitor that
discerns which variant of the KeyTrie applies. With this change, the
above failure becomes:
> Bad config: No command named 'buffer_close' for key `keys.normal.b` at line 2 column 5
> Press <ENTER> to continue with default config
We also provide more explicit information about the expectations on
the field. A config with an unexpected type produces a message with
that information and the expectation:
[keys.normal]
b = 1
> Bad config: invalid type: integer `1`, expected a command, list of commands, or sub-keymap for key `keys.normal.b` at line 2 column 5
> Press <ENTER> to continue with default config

* Add command line parameter to specify log file
I had the logs of my debug helix mixed in with the logs from the
production helix.
Add a `--log` command line argument to redirect any logs to other
files, making my debugging easier :-)
* Update completion files with `--log` argument
Applying document-change transactions to diagnostic ranges is not stable
with respect to the ordering of diagnostics. This can cause diagnostics
to become temporarily unordered with some edits to a document, which can
eventually break some invariants/assumptions in syntax::merge.
With this change, Document::diagnostics are always sorted.

Marksman is an LSP server for Markdown: https://github.com/artempyanykh/marksman
It supports a bunch of LSP features: symbols, references, rename, diag,
etc. and already has integrations with emacs, neovim, and vscode.
When looking up the runtime/ directory relative to the executable path,
canonicalize the path first in case the executable is a symbolic link.
