Improve developer experience baseline

[deancochran]

Summary

• Add a repo doctor script for local tool/env/port diagnostics.
• Split web dev startup into local and tunnel modes so default web dev no longer requires ngrok.

• Refresh README guidance for the current shared dev workflow and existing mobile scripts.

Validation

• pnpm install --frozen-lockfile
• pnpm run doctor
• pnpm check

• pnpm knip

Notes

Point local SMTP at Inbucket's SMTP port

With this template, any developer who copies apps/web/.env.example and uses AUTH_EMAIL_MODE=smtp will send Nodemailer to port 54324. In our Supabase config that port is the Inbucket web UI (packages/db/supabase/config.toml:92-95); the SMTP listener is 54325, so verification/reset emails fail to send instead of appearing in Inbucket. Set this to 54325 or change the Supabase SMTP port to match.
