Till JS 49935c9628 feat(shared-privacy): M1 — visibility foundation package
Scaffold the unified visibility/privacy layer introduced by docs/plans/
visibility-system.md. No module adopts it yet — this is the foundation
PR (M1). Module rollout lands in follow-ups starting with Library (M2).

What ships:
- @mana/shared-privacy package
  - VisibilityLevel enum ('private' | 'space' | 'unlisted' | 'public')
  - VisibilityLevelSchema + UnlistedTokenSchema (zod)
  - defaultVisibilityFor(spaceType): personal → private, else → space
  - predicates: canEmbedOnWebsite, isReachableByLink,
    isVisibleToSpaceMember, canAiAccessCrossUser (always false in P1)
  - generateUnlistedToken() — 32-char base64url, CSPRNG, ~192 bits
  - VISIBILITY_METADATA: German labels + descriptions + phosphor icon
    names so non-UI surfaces (audit logs, CLI) label levels consistently
  - <VisibilityPicker> svelte component: compact lock/globe trigger with
    4-option menu, full descriptions, optional compact + disabledLevels
- VisibilityChangedPayload type for the domain-event catalog (consumer
  registers it when the first module adopts the system)
- .claude/guidelines/visibility.md — step-by-step for module authors
  (schema migrations + store wiring + picker placement + embed resolver +
  legacy isPublic migration), with a pre-PR checklist
- Plan-doc "Offene Fragen" section rewritten as "Designentscheidungen"
  with the seven resolutions the user approved
- CLAUDE.md: shared-privacy listed in the packages table; visibility.md
  listed in the guidelines table
- 15 unit tests covering predicates (one-and-only-one 'public' for
  embed; phase-1 AI always-deny), defaults (personal vs multi-member,
  null fallback), token uniqueness + schema round-trip

Key constraints honored:
- `visibility` stays plaintext (NOT added to the encryption registry)
  so RLS predicates and publish resolvers can read it without the user's
  master key
- Publish flow remains "decrypt client-side, inline plaintext into
  snapshot" — the pattern picture.board already uses in embeds.ts
- Deny-by-default everywhere (personal default = private; unknown space
  type defaults to private; cross-user AI always false)

Not in this PR (per plan):
- No schema migrations in any module (M2–M6)
- No RLS predicate updates (arrives with M2)
- No /settings/privacy overview (M7)
- No unlisted share routes (M8)
