## Summary
- Wire a toast on every click of **View Vault** so users always see a result; surface the vault path in the toast.
- Add a **Reveal Folder** fallback action so users without Obsidian still have an OS-native escape hatch to inspect the vault.
- Add a `revealPath` helper (wraps `tauri-plugin-opener`'s `revealItemInDir`) + `opener:allow-reveal-item-in-dir` capability so the renderer can drive a Finder/Explorer reveal.
- 6 new Vitest cases cover the success-toast, reveal-fallback, error-toast, and reveal-error branches.
## Problem
`MemoryWorkspace.tsx` View Vault sent `obsidian://open?path=...` through `openUrl` and relied on the host OS to launch Obsidian. When Obsidian is not installed, the OS shell (LaunchServices on macOS, xdg-open on Linux, ShellExecute on Windows) accepts the URL handoff but launches nothing. No toast, no error, no fallback — the button looks broken to non-technical users.
## Solution
- New `revealPath(path)` helper in `app/src/utils/openUrl.ts` wraps `revealItemInDir` from `@tauri-apps/plugin-opener`. No-op outside Tauri.
- Capability `app/src-tauri/capabilities/default.json` adds `opener:allow-reveal-item-in-dir`.
- `MemoryWorkspace.tsx` replaces the silent module helper with a `handleViewVault` callback. On click:
- Try `openUrl(obsidian://...)`.
- On success: emit an `info` toast that names the vault path and exposes a **Reveal Folder** action.
- On error: emit an `error` toast with the same **Reveal Folder** action.
- **Reveal Folder** calls `revealPath(content_root_abs)`; if that fails too, surface a final error toast with the underlying message.
- New i18n keys (`workspace.openingVault*`, `workspace.openVaultFailed*`, `workspace.revealFolder`, `workspace.revealVaultFailed`) added to `en.ts` + `en-3.ts`, with English fallback into all 11 non-en `-3` chunks so `pnpm i18n:check` exits 0.
## Submission Checklist
- [x] Tests added or updated (happy path + at least one failure / edge case) per Testing Strategy — 6 new Vitest cases across `MemoryWorkspace.test.tsx` and `openUrl.test.ts`.
- [x] **Diff coverage ≥ 80%** — every new branch in `handleViewVault` and `revealPath` has a dedicated test.
- [x] Coverage matrix updated — N/A: behaviour-only fix for an existing UI affordance; no new feature row needed.
- [x] All affected feature IDs from the matrix are listed in the PR description under `## Related` — N/A: no matrix row affected.
- [x] No new external network dependencies introduced — no network calls added.
- [x] Manual smoke checklist updated if this touches release-cut surfaces — N/A: not on the release-cut surface list.
- [x] Linked issue closed via `Closes #NNN` in the `## Related` section.
## Impact
- **Runtime/platform**: desktop (mac/win/linux). No mobile/web/CLI surfaces touched.
- **Performance**: zero — a single extra toast emit + (optional, user-driven) `revealItemInDir` IPC call.
- **Security**: new capability permission is read-only filesystem-reveal scoped to the host file manager; no path escape.
- **Migration / compatibility**: backward-compatible. Existing `obsidian://` deep-link behaviour preserved for users with Obsidian installed.
## Related
- Closes: #2281
- Follow-up PR(s)/TODOs: maintainer-side translations of the new keys (English fallback shipped so `i18n:check` passes).

### Validation Blocked
- `command:` N/A
- `error:` N/A
- `impact:` N/A
### Behavior Changes
- Intended behavior change: Clicking **View Vault** now always emits a toast with the vault path and a **Reveal Folder** fallback, instead of silently no-op-ing when Obsidian is not installed.
- User-visible effect: visible toast + working fallback on every click.
### Parity Contract
- Legacy behavior preserved: `obsidian://` deep link still dispatched first; users with Obsidian installed see Obsidian launch as before.
- Guard/fallback/dispatch parity checks: `openUrl` reject path still propagates non-http scheme errors; new error branch in `handleViewVault` surfaces those as user-facing toasts.
