What does this PR do?

A command .md file with a model that isn't provider/model in its frontmatter (for example model: opus) was dropped without any log. decode() in config/plugin/command.ts validated all of the frontmatter with one schema, so a bad model made the whole decode fail and the command never showed up.

Now the loader checks model on its own first. If it isn't a valid provider/model reference, it logs a warning with the file path and the value, drops the field, and loads the command without a model override, so it runs on the session's model (or the command agent's, if it sets one), as the issue suggests. Invalid values in other fields behave as before.

How did you verify your code works?

Added a test to packages/core/test/config/command.test.ts that loads a real commands/hello.md with model: opus. It checks that the command is listed, runs without switching the model, and logs one warning naming the file and opus. Without the fix it fails because the command list is empty.

In packages/core, bun run test test/config/ passes (209 tests), and typecheck, prettier and oxlint are clean. I ran this on Linux arm64 and didn't try it in the TUI.
