Oracle: behavior goldens for every impeccable verb

lib.mjs runs each case (verb + args + staged workspace + stdin) against an implementation and captures stdout, stderr, exit code, and named files, with machine-specific paths and timestamps normalized.

• record.mjs writes goldens from the JS scripts (skill/scripts, cli/bin).
• run.mjs replays the corpus against $IMPECCABLE_BIN (or --js for a self-check) and diffs. Byte-equal is the bar; DELTAS.md lists reviewed exceptions.
• cases/*.mjs define the corpus (default export: array or async function returning an array). workspaces/ holds project fixtures that are copied to a temp dir per run, so cases can write freely.

Adding a case: append to the matching cases/*.mjs, run node tests/oracle/record.mjs <prefix>, commit the golden.

Verb names are the binary's subcommands. cli-help and cli-version map to impeccable --help / --version.
