Till JS 1771063df4 refactor(actor): identity-aware Actor for Multi-Agent Workbench (Phase 1)
Foundation for the Multi-Agent Workbench roadmap
(docs/plans/multi-agent-workbench.md). Every event, record, and
sync_changes row now carries a principal identity + cached display
name in addition to the three-kind discriminator.

Shape change (source of truth in @mana/shared-ai):
  Before: { kind: 'user' | 'ai' | 'system', ...kind-specific fields }
  After:  discriminated union on kind, with
            - common:  principalId, displayName
            - 'user':  principalId = userId
            - 'ai':    principalId = agentId + missionId/iterationId/rationale
            - 'system': principalId = one of SYSTEM_* sentinel strings
                        ('system:projection', 'system:mission-runner', etc.)

Key design calls (from the plan's Q&A):
- System sub-sources get distinct principalIds (not a shared 'system'
  bucket) — lets Workbench filter + revert distinguish projection
  writes from migration writes from server-iteration writes
- displayName cached on the record so renaming an agent doesn't
  rewrite history
- normalizeActor() compat shim fills principalId/displayName on
  legacy rows with 'legacy:*' sentinels so historical events never
  crash the timeline

New exports:
- BaseActor / UserActor / AiActor / SystemActor (narrowed types)
- makeUserActor, makeAgentActor, makeSystemActor (factories with
  typed return)
- SYSTEM_PROJECTION, SYSTEM_RULE, SYSTEM_MIGRATION, SYSTEM_STREAM,
  SYSTEM_MISSION_RUNNER (principalId constants)
- LEGACY_USER_PRINCIPAL, LEGACY_AI_PRINCIPAL, LEGACY_SYSTEM_PRINCIPAL
- isUserActor / isFromMissionRunner predicates

Webapp:
- data/events/actor.ts now re-exports from shared-ai, keeps runtime
  ambient-context (runAs, getCurrentActor) local
- bindDefaultUser(userId, displayName) lets the auth layer replace
  the legacy placeholder with the real logged-in user actor at login
- Mission runner + server-iteration-staging stamp LEGACY_AI_PRINCIPAL
  as the agentId placeholder — Phase 2 will thread the real agent
- Streaks projection uses makeSystemActor(SYSTEM_PROJECTION)
- All test fixtures migrated to factories

Service:
- mana-ai/db/iteration-writer.ts stamps makeSystemActor(
  SYSTEM_MISSION_RUNNER) instead of the old { kind:'system',
  source:'mission-runner' } shape. Phase 3 will switch this to an
  agent actor per mission.

Tests: 26 shared-ai + 21 webapp vitest + 35 mana-ai — all green.
svelte-check: 0 errors, 0 warnings.

No behavior change; purely a type + shape upgrade. Old sync_changes
rows parse via the normalizeActor compat shim at read time.
