Knowledge Finalize

Phase 7 of the inverted pipeline. Reads <project>/output/draft-vN.md + <project>/.metadata/verify-vN.json + <project>/.metadata/citation-manifest.json, runs cycle-guard.py to refuse self-citing loops, deposits the verified draft as <WIKI_ROOT>/wiki/syntheses/<synthesis-slug>.md, runs three cogni-wiki helpers (wiki_index_update.py, config_bump.py, rebuild_context_brief.py) directly at script level, appends a research_projects[] entry to binding.json, writes one ## [YYYY-MM-DD] finalize | … line to wiki/log.md, and runs a Step 10.5 conformance gate (lint_wiki.py --fix=all + health.py) so the deposited base passes cogni-wiki's own structural checks.

This is the inverted-pipeline closing step. Without it, every verified draft lives forever in <project>/output/ and the wiki cannot accumulate cross-source framing — the compounding property that differentiates cogni-knowledge from one-shot deep-research tools requires future knowledge-compose runs to read wiki/syntheses/*.md as prior context. Finalize is what makes that read non-empty.
