Impeccable Files

The i- command prefix is gone. Opting into a prefix at install time was a holdover from when every command was its own skill. With a single impeccable skill it only ever renamed that one skill to i-impeccable, while the install message wrongly promised /i-audit style commands that never existed, and the rename could clobber unrelated third-party skills in the same harness folder. The flag and the prompt are removed.

Existing prefixed installs heal themselves. skills install and skills update now rename any old i-impeccable (or custom-prefixed) skill back to the canonical impeccable, scoped by name so a third-party skill that happens to start with i- is left untouched. Want a short top-level command? /impeccable pin audit still makes /audit a standalone shortcut.
