Minor Changes

• Write-time broken-link validation in the Open Knowledge MCP. write/edit now return brokenLinks in the same response — outbound links that don't resolve are surfaced at write time, report-only so the write still lands and you can author a doc before its link target exists. Validation covers every local link, not just docs: the ./-onto-a-content-root-path doubling footgun and missing [[wiki]] / markdown doc targets (no-such-doc), root-escaping paths from one ../ too many (unresolvable), and links to assets or source files ([src](../../foo.py)) that don't exist on disk at the resolved path (no-such-file). That last reason closes the gap a real codebase-wiki run hit: wrong-depth source-file links that 404 silently because the doc-only link graph never tracked them. The platform and pack skills are updated to point agents at brokenLinks as the primary write-time check and to clarify that a same-pass forward-reference reports as no-such-doc until its target lands (the links({ kind: "dead" }) audit is the authoritative end-state check).
