rename(phase 1): CapaKraken → Nexus across code, UI, docs, CI

- @capakraken/* → @nexus/* across 12 packages (root + 11 workspaces),
  1551 import lines migrated via codemod
- User-visible brand strings renamed (emails, page titles, PWA
  manifest, mobile header, MFA backup-codes header, tooltips, signin
  page, invite page, weekly digest, install prompt)
- TOTP issuer "CapaKraken" → "Nexus" (existing secrets still valid;
  re-enrollment relabels them in users' authenticator apps)
- Function rename: assertCapaKrakenDbTarget → assertNexusDbTarget
- LocalStorage migration shim in apps/web/src/app/layout.tsx copies
  capakraken_* → nexus_* on first load (guarded by nexus_migrated_v1
  sentinel; runs once per browser, then never again)
- Service-worker cache name capakraken-v2 → nexus-v2 with one-time
  caches.delete('capakraken-v2') from the same shim
- Email-domain fixtures @capakraken.{dev,app} → @nexus.{dev,app} in
  seed data, e2e specs, SMTP default fallback
- Dockerfile.dev / Dockerfile.prod / all .github/workflows/*.yml
  pnpm --filter @capakraken/* → @nexus/*
- README, CLAUDE.md, LEARNINGS.md, all docs/*.md, .env.example,
  tooling/deploy/.env.production.example brand sweep

Phase 1 deliberately leaves untouched (handled in Phase 3 cutover):
- PostgreSQL DB name "capakraken" and POSTGRES_USER "capakraken"
- Volume names capakraken_pgdata etc.
- Compose project name "capakraken" / "capakraken-prod"
- db-target-guard default expectedDatabase
- env-var CAPAKRAKEN_EXPECTED_DB_NAME
- Container DNS names in docker-compose.ci.yml

Quality gates green: pnpm typecheck (7/7), pnpm test:unit (7/7),
pnpm lint (0 errors), check:exports/imports/architecture all pass.

 ### Triage Notes
 
 **P1 — Bugs (blocking):**
+
 - **#3** — Blueprints likely not seeded in the new Gitea DB, or the query returns empty. Quick check of `blueprint.list` query.
 - **#5** — User account created but `Resource.userId` not linked. Need to link Larissa's account to her resource record.
 - **#7** — Chapter dropdown filter in VacationClient resets options after selecting one. Likely a state management bug in the filter component.
 
 **P2 — Bugs (non-blocking):**
+
 - **#6** — AppShell sidebar highlights both "My Vacations" and "Vacation Mgmt" simultaneously. URL path matching issue.
 - **#10** — Sick leave entries (vacation type SICK) not showing on timeline. The timeline `getEntries` query likely filters vacation types.
 
 **P3 — UX/Feature (quick wins):**
+
 - **#8** — VacationClient uses same color for all vacation types. Add type-specific colors.
 - **#4** — Add "Total Hours" and "Total Costs" columns to ProjectAssignmentsTable.
 - **#2** — Add search bars to Timeline page matching Allocations page layout.
 
 **P4 — Feature (larger scope):**
+
 - **#9** — User preferences system (new DB field or localStorage) for default filter state.
 - **#1** — Project color field + color picker in UI + timeline rendering by project color.
 
 ## Agent Spawning Strategy
 
 ### For bugs (S effort):
+
 Direct fix in main context — no worktree needed. Read, fix, test, commit.
 
 ### For features (M effort):
+
 Spawn a **coder** agent with `isolation: "worktree"` to keep main clean. Review output before merging.
 
 ### For features (L effort):
+
 Spawn a **planner** agent first to create implementation plan. Then spawn **coder** agent per task in the plan. Requires user approval at each stage.
