What does this PR do?

For projects without a server registration (id-less / "global" projects), the edit dialog writes the new name, commands, and icon to the per-workspace projectMeta cache. But enrich() in global.tsx and layout.tsx only merged the legacy childStore.icon override, so the renamed name and startup command were silently ignored in the project list.

This adds a mergeProjectMeta helper and applies it in both enrich() functions before the existing icon override. The enriched list is consumed by the sidebar, session tabs, command palette, and directory picker, so local renames now display everywhere. Server-registered projects keep their server values unless a local override exists.

How did you verify your code works?

• Added unit tests for mergeProjectMeta: local name applied for id-less projects, server name kept when local has no name, empty name falls back to the folder-derived name, and icon + commands merge.
• bun test src/context/global-sync/utils.test.ts: 11 pass (6 existing + 5 new), 0 fail.
• bun typecheck in packages/app: 0 errors.
• Confirmed a production desktop build (OPENCODE_CHANNEL=prod) renders the fix.

Screenshots / recordings

this is a display-logic fix on the enriched project list, not a visual UI change. Prior local renames appear once the app rebuilds with this change.
