feat(electrobun): ProjectWizard — 3-step project creation with 5 source types

Step 1 — Source: local folder (path browser + validation), git clone,
GitHub URL, template (4 built-in), remote SSH
Step 2 — Configure: name, branch selector, worktree toggle, group, icon, shell
Step 3 — Agent: provider, model, permission mode, system prompt, auto-start

- ProjectWizard.svelte: 3-step wizard with display toggle (rule 55)
- PathBrowser.svelte: inline directory browser with breadcrumbs + shortcuts
- git-handlers.ts: git.branches + git.clone RPC handlers
- files.statEx RPC: path validation + git detection + writable check
- 39 new i18n keys, 172 total TranslationKey entries
- App.svelte: wizard overlay replaces simple add-project card
