bump-prerelease.ts

/**
 * Bump package versions for a prerelease (runs in the secrets-free build job).
 *
 * This is extracted from prerelease.ts so that version bumping happens before
 * the build, in a job that has no access to NPM_TOKEN or other publish secrets.
 * The publish job then receives pre-built, correctly-versioned artifacts.
 *
 * Usage: tsx scripts/release/bump-prerelease.ts --scope <monorepo|angular> [--suffix <label>]
