provider ' ' does not support removing packages

Error message

provider '{}' does not support removing packages

What it means

Companion to add_command: the default `DepsProvider::remove_command` implementation bails for providers that cannot uninstall dependencies. Calling package removal on such a provider fails with the provider's id in the message.

Solutions

1. Use a provider that supports removal (overrides `remove_command`)
2. Remove the dependency with the underlying package manager directly and regenerate the lockfile
3. Implement `remove_command` if this is your own provider

Example fix

// before
mise deps remove serde   # provider lacks remove support
cargo remove serde       # via the package manager directly
// after
mise use cargo
mise deps remove serde

match provider.remove_command(pkgs) {
    Ok(cmd) => run(cmd),
    Err(_) => fallback_to_native_pm(provider.id(), pkgs), // e.g. `cargo remove`
}

When it happens

Trigger: Running a deps-remove operation whose selected provider has not overridden `remove_command`.

Common situations: `mise deps remove <pkg>` against a provider backed by a read-only or lockfile-only source; assuming removal parity with add/list support.
