revert(co-dialectic): restore ~/anand-career-os paths in T4 precheck docs

Prior commit incorrectly treated ~/anand-career-os/brain/identity/experience-history.md
as a private path leak. It is intentional skill documentation — the marketplace
installs private repos; relative ~/paths in skill text are not leaks.

Restoring original T4 biographical precheck references on lines 385 + 413.
Leak check in test-plugin-install.sh tightened to absolute paths only.

Until it ships, run hallucination-detector with `--rubric hallucination` as fallback. Mark in output: `(bio-claim verifier: pending career-os integration — using hallucination-detector fallback)`.
