fix: resolve webpack module resolution error with wrapper component

Root cause analysis:
- Next.js 16 Server/Client Component boundary issue
- Webpack module chunking fails with named exports from Client Components
- Error: "Cannot read properties of undefined (reading 'call')"

Solution:
- Created release-sidebar-wrapper.tsx to isolate import boundary
- Server Component (layout.tsx) now imports via wrapper
- Wrapper uses default export, which webpack handles better

Technical details:
- Server Component -> direct import -> Client Component = module undefined
- Wrapper component breaks the problematic import chain
- Default exports handle webpack chunking more reliably than named exports

Documentation:
- Added comprehensive troubleshooting guide
- Documents 4 solution approaches
- Lists best practices to prevent future occurrences
- Identifies other potential problem areas in codebase

Files changed:
- app/(marketing)/releases/layout.tsx (import via wrapper)
- app/(marketing)/releases/components/release-sidebar-wrapper.tsx (new)
- docs/troubleshooting/webpack-module-resolution-error.md (new)
