chore: disable Vercel previews for Dependabot branches

[spizeck]

Summary

Prevents Dependabot branches from creating Vercel Preview Deployments via git.deploymentEnabled in vercel.json.

Why dependabot/** and not dependabot/*: Vercel matches branch names with minimatch, where * never crosses /. Real Dependabot branches are nested — e.g. dependabot/npm_and_yarn/functions/eslint-10.11.0 — so a single-star dependabot/* pattern matches none of them. The ** glob is required for the exclusion to actually take effect.

A Preview Deployment triggers downstream integrations — for projects with the Vercel↔Neon integration, each preview provisions an isolated database branch. Blocking the deployment before it is created (rather than skipping the build with an Ignored Build Step, which still creates the deployment) avoids that infrastructure entirely.

Behavior

Push to	Vercel deployment
main/master	Production — unchanged
feat/*, fix/*, ordinary PR branches	Preview — unchanged
dependabot/**	None — no deployment, no preview integrations

Validation

• vercel.json parses as valid JSON; all existing keys (crons, rewrites, functions, buildCommand) preserved
• git.deploymentEnabled["dependabot/**"] === false; no overlapping true rule exists
• Verified against real Dependabot branch names in this org (dependabot/npm_and_yarn/…, 3–4 segments deep)

Reviewer's Guide

Updates vercel.json to prevent Vercel from creating deployments—and therefore downstream preview infrastructure—for nested Dependabot branches, while leaving production and ordinary preview behavior unchanged.

File-Level Changes

Disable Vercel Preview Deployments for all Dependabot branch paths using a recursive glob exclusion.	Add a git.deploymentEnabled rule mapping dependabot/** to false. Preserve existing Vercel configuration for production deployments, ordinary previews, cron jobs, rewrites, functions, and build settings.	vercel.json
