#248 — orpc-v2: consolidate fork into everything-dev and migrate platform to oRPC v2 + Effect 4 (epic)

What to build

Bring citynode.app main up to date with everything-dev main (upstream is 5 commits ahead: relayer fixes, null overrides, send, lint, version packages) so the fork becomes a strict superset of upstream and the M1 merge is a clean fast-forward.

Resolve conflicts where both sides touched the same files — the auth plugin's relayer configuration is the expected hotspot. Preserve both intents: upstream's relayer/null-override fixes and the fork's auth-plugin work.

Acceptance criteria

• citynode.app main contains every everything-dev main commit (zero behind, still ahead)
• Conflicts resolved preserving upstream's relayer/override fixes and the fork's auth work
• bun run test, bun typecheck, bun lint green on the merged main
• Fork runtime identity untouched (bos.config.json account/gateway/deploy URLs unchanged)

Blocked by

None (can start immediately).

Compare citynode.app main with everything-dev main and review the five upstream commits before merging. Resolve the auth-plugin relayer conflict while retaining both sides' changes, then run bun run test, bun typecheck, and bun lint; done means the branch is zero commits behind, still ahead, and bos.config.json identity values are unchanged.
