**Removed the native `commander` binding** — `import { Command } from "commander"` now resolves to
the real npm package, compiled from source. Native `program.args` was `undefined`; boolean option
defaults serialized as the truthy string `"false"`; subcommand `.action()` callbacks never fired;
missing-required-argument and unknown-option validation (Node's `commander.missingArgument` /
`commander.unknownOption`) was entirely absent. `class Command extends EventEmitter` in the real
source needs no dedicated native-subclass support — Perry's existing generic EventEmitter-subclass
machinery already covers it. Fixes #10686. Requires #10439's import-provenance fix (#10699) to reach

Remove the unrelated Fixes #10686`` reference.

Issue #10686 tracks lazy-initialization and array-like performance costs. This change removes the native Commander binding. It does not resolve that issue. Replace this reference with the Commander tracking issue, if applicable.

Based on learnings: changelog fragments must describe one coherent shipped behavior.

In `@changelog.d/10712-remove-commander-binding.md` at line 7, Remove the
unrelated “Fixes `#10686`” reference from the changelog fragment and replace it
with the appropriate Commander tracking issue reference, if one exists. Keep the
fragment focused on removing the native Commander binding and preserve the
existing import-provenance note.
