Fix critical build and analysis rerun failures

[cursor]

Bug and impact

• Build This App swallowed AI generation and GitHub/GitLab push failures, then emitted a terminal done SSE event. Users could be told a repo was successfully built even when files were missing, placeholder error files were pushed, or writes failed.
• GitHub repos created by Build This App were public by default, risking exposure of generated proprietary code.
• Analysis reruns deleted existing blueprints before the replacement analysis succeeded, so any GitHub/AI/database failure could permanently remove prior results.

Root cause

• Build failures were converted to warnings or placeholder content instead of terminal errors, and push helpers did not throw on non-2xx responses.
• The GitHub create-repo request used private: false.
• /api/analyses/[id]/run called deleteBlueprintsByAnalysis at the start of the rerun before new blueprint rows existed.

Fix

• Build This App now deduplicates file paths, creates GitHub repos privately, throws on generation/empty-output/push failures, and emits terminal SSE error without done.
• Analysis reruns now insert the full replacement set first, clean up partial replacement rows on insert failure, and delete older blueprints only after all new rows are persisted.

Validation

• pnpm exec eslint app/api/build-app/route.ts app/api/analyses/[id]/run/route.ts lib/queries.ts (passes with one pre-existing warning in lib/queries.ts)
• pnpm exec tsc --noEmit
• Temporary mocked route harness verified build success, generation failure, push failure, GitHub private repo creation, duplicate file dedupe, successful blueprint replacement cleanup, and failed replacement preserving old blueprint rows.
