Summary

Resolves all 8 open issues in a single PR:

Critical / Build

• Closes build: restore a memory-safe TypeScript typecheck pipeline #67 — TypeScript typecheck OOM: Split into 5 tsconfig project configs. Typecheck now completes in ~3s without --max-old-space-size=8192 workaround.

High Priority

• Closes feature: add Claude Mem import adapter for observations, summaries, and prompts #71 — Claude Mem import adapter: Format detection, observation/summary/prompt transformation, provenance tracking, SHA256 dedup. 42 tests.
• Closes feature: add external import autodetect, dry-run reporting, and migration guide #72 — Import autodetect, dry-run reporting, migration guide: Enhanced CLI UX with colored output, format detection messaging, docs/migration-guide.md.
• Closes feat: condivisione read-only con JWT token #33 — Read-only sharing via JWT: Token generation/revocation, scoped viewer endpoint, CLI share create/list/revoke commands. 22 tests.
• Closes feat: team sync via Git — export/import knowledge base condivisa #34 — Team sync via Git: Markdown export with YAML frontmatter, team init/push/pull CLI commands, local-wins merge strategy.

Medium Priority

• Closes ux: clean web viewer and CLI branding surfaces, version display, and legacy alias messaging #70 — Branding cleanup: Legacy alias deprecation notice for kiro-memory command, Total Recall as canonical product name.
• Closes feat: VS Code extension completa con sidebar, comandi e webview #35 — VS Code extension: CodeLens provider, QuickPick search (Ctrl+Shift+K), status bar, configuration settings.
• Closes feat: dashboard multi-utente con permessi e ruoli #36 — Multi-user dashboard: Roles (admin/editor/viewer), bcrypt auth, HMAC-SHA256 JWT, audit log, invite-only registration. 26 tests.

What was tested

• npm run typecheck — passes (all 5 configs, ~3s total, zero OOM)
• npm run build — passes
• New test suites: 90+ tests across adapters, sharing, auth, team sync
• Greploop code review pass (security, correctness, quality)

Architecture decisions

• TypeScript configs split by layer: shared → runtime/services → product → ui
• Multi-user mode disabled by default (single-user, no auth friction)
• JWT sharing uses self-contained HMAC-SHA256 (no external JWT library for auth-middleware)
• Team sync uses child_process git commands (no git library dependency)
• Claude Mem adapter follows extensible registry pattern for future import sources
