Quality-first MCP clean cutover

[jamil2018]

Summary

• replace the mixed lifecycle MCP surface with one annotated Quality-first contract
• remove legacy Plan, baseline, implementation, provider-run, and pending lifecycle paths
• add destructive schema migration plus durable Quality validation publication, Assessment execution, evidence reconciliation, and cancellation semantics
• replace legacy UI with Quality Plans and Assessments lifecycle/evidence views
• synchronize create-appraisejs templates, current docs, generated MCP artifacts, and Graphify output

Validation

• npm run validate:unit (180 files, 683 tests)
• npm run build
• npx tsc --noEmit
• Prisma schema validation/generation and full 73-migration chain
• populated destructive migration cutover test with PRAGMA foreign_key_check
• AppraiseJS package tests/build and create-appraisejs package tests
• MCP contract/registry/security tests
• focused Quality execution, evidence, UI, navigation, and settings tests
• Playwright: 40/41 initial; obsolete Sync Plans expectation corrected; focused navigation/settings 14/14
• Browser smoke: Quality Plans and Assessments render; removed /plans returns 404
• npm run graphify:auto
• npm run quality:fallow:commit
• npm run quality:react-doctor:commit
• independent final cutover review: ACCEPTED

Notes

• The migration is an intentional clean cutover and includes a populated pre-cutover database preservation/drop-table test.
• Unrelated local auth automation changes and untracked appraise/ artifacts were excluded from this commit.
