v1.1.1 — DOX health audit & auto-repair prompts

Adds two "How to use" prompts for keeping a DOX tree correct when a weaker model skips a step or the repo is edited by hand. Docs only — no framework changes.

New prompts

• Health audit (read-only). Reports boundary coverage at every depth, Child DOX Index completeness, Feature Map file references, Child Doc Shape conformance, and parent/child contract conflicts — grouped by severity with paths and suggested fixes. Never edits.
• Auto-repair. Runs the same audit, then fixes the mechanical problems (missing boundary/sub-root docs, broken indexes, stale Feature Map entries, shape issues). Edits docs only, never source, and defers genuine judgment calls back to you.

Each ships with an explicit numbered prompt, a collapsed short form for capable/frontier models, and a scoped single-area variant.
