* fix: [ci-fix] upgrade supabase/setup-cli from v1 to v2

The v1 action targets node20 (deprecated on GitHub Actions runners) and its
latest-version resolver returns HTTP 404. Upgrading to v2 which ships with
node24 support, removing the FORCE_JAVASCRIPT_ACTIONS_TO_NODE24 workaround.

* fix: [ci-fix] revert supabase/setup-cli to v1 — v2 returns 404 on CLI download

supabase/setup-cli@v2's bun-based download logic gets HTTP 404 when
fetching the CLI binary. Revert to v1 with FORCE_JAVASCRIPT_ACTIONS_TO_NODE24
until the v2 action is fixed upstream.

* fix: [ci-fix] upgrade supabase/setup-cli v1 to v2

supabase/setup-cli@v1 returns HTTP 404 when downloading the CLI binary,
breaking the staging required check on all PRs. v2 is a composite action
using Bun instead of Node.js, so the FORCE_JAVASCRIPT_ACTIONS_TO_NODE24
env var is no longer needed.

* fix: [ci-fix] revert deploy-migrations.yml to v1 — v2 still returns 404 on CLI download

The supabase/setup-cli@v2 action fails with HTTP 404 when resolving
'version: latest'. This was already discovered and reverted once on this
branch. Restore the v1 action with FORCE_JAVASCRIPT_ACTIONS_TO_NODE24
workaround to unblock CI.

+# Performance Report — Week 21
+
+## Health Endpoint
+- Status: ok
+- DB latency: 339ms ✅
+- DB connected: yes
+
+## Error Trend
+- This week: unavailable (Sentry MCP tools not accessible)
+- Last week (W20): unavailable
+- Trend: unknown
+
+> Sentry error counts could not be queried — MCP integration was not available during this run. Manual check recommended via https://de.sentry.io for org `ona-2j`, project `memo`.
+

+### Build Size vs W20
+
+| Page | W20 | W21 | Delta |
+|---|---|---|---|
+| / | 250.1 kB | 193.5 kB | −56.6 kB ↓ |
+| /sign-in | 271.6 kB | 218.5 kB | −53.1 kB ↓ |

+
+Shared base dropped from 252.0 kB (19 chunks) to 170.1 kB (7 chunks) — a 32% reduction, likely from Next.js 16.2.6 Turbopack improvements and chunk consolidation.
+
+## Action Items
+- DB latency improved significantly: 658ms (W20) → 339ms (W21), now within the 500ms threshold. No action needed.
+- Home page (/) is now under the 200 kB budget at 193.5 kB. 8 of 9 measured pages still exceed 200 kB but all are under 225 kB — a substantial improvement from W20 where all pages exceeded 250 kB.
+- Sentry error trend could not be checked — verify MCP integration is configured for the Performance Monitor automation.
+- No critical issues detected this week.
