5e13abd67c A non-Unicode command-line argument is a usage error, not a startup panic (#1108) (#1168)
* fix(apps): a non-Unicode argument is a usage error, not a startup panic (#1108)

Both binaries read `std::env::args()`, which panics on an argument that is
not valid Unicode: `photocraft-cli info $'caf\xe9.png'` died in
`library/std/src/env.rs` before printing anything, and a file manager
handing the desktop app a Latin-1 file name would do the same before any
window opened.

CLI: `photocraft_cli::run_os` takes the raw `OsString`s, and an argument
that does not convert is a usage error naming its position and a lossy
rendering (exit 2, with the usage text), like any other bad argument.
`main` calls it; `run(&[String])` is unchanged for in-process callers.

Desktop: the loop matches on `OsStr::to_str`. Flag values that are paths
(`--control-token-file`, `--automation-*-root`) become `PathBuf`s directly
and so keep working with any name; a non-Unicode `--control-token` is a
control-argument error like a bad `--control` port; non-Unicode file
arguments are collected and reported in a "Could not open" notice once the
app is up, so the launch still succeeds.

Test: `a_non_unicode_argument_is_a_usage_error_not_a_panic` (unix) runs
the binary with a `caf\xe9.png` argument for `info` and `convert` and
asserts exit 2, the message, and no panic output.

* photocraft-cli: put run()'s doc line back above run, not run_os
