chore: webpack build

[rebelchris]

Problem

Extension builds were failing with ERROR in [entry] [initial] js/newtab.bundle.js Invalid array length after commit 4d36738 which added OpportunityEditRecruiterModal.

Root Cause

The modal imports from lib/schema/opportunity.ts, which contains complex zod validation schemas. When webpack processes this file during extension builds, Next.js 15.4.10's Babel plugin attempts to optimize/rewrite code patterns and hits a bug when processing:

• Large numeric literals with underscores (100_000_000, 1_000_000)
• Complex nested zod schemas with refinements
• Dynamic array patterns like [0, 0.5, 1].map(item => z.literal(item, {...}))

The Babel regex rewriting plugin creates an invalid internal array structure, causing the "Invalid array length" error.

Solution

Conditionally exclude opportunity-related modals from extension builds by checking process.env.TARGET_BROWSER at compile time. These modals are webapp-only features (job posting management) and should never be loaded in the extension anyway.

Why this approach:

• ✅ Webpack performs compile-time replacement of process.env.*, enabling proper tree-shaking
• ✅ The problematic imports are never processed during extension builds
• ✅ No impact on webapp functionality
• ✅ Cleaner than trying to rewrite complex zod schemas or webpack exclusions

Changes

• packages/shared/src/components/modals/common.tsx: Wrapped OpportunityEditModal and OpportunityEditRecruiterModal in conditional checks
• packages/shared/src/lib/schema/opportunity.ts: Minor optimization of roleType union (changed from .map() to explicit literals)

Testing

• ✅ Extension build completes successfully
• ✅ Webapp build unaffected (modals load normally)
• ✅ Extension doesn't include unnecessary opportunity modal code

Notes

This is a workaround for a Next.js 15.4.10 Babel bug. The issue may be resolved in future Next.js versions, but this approach has the added benefit of reducing extension bundle size by excluding webapp-only features.
