style: rustfmt vault_list.rs

Add ability to remove vaults from the app list without deleting files on disk,
and restore the bundled Getting Started demo vault when needed.

Changes:
- Rust: add hidden_defaults field to VaultList for tracking removed default vaults
- useVaultSwitcher: add removeVault() and restoreGettingStarted() with auto-switch
- useCommandRegistry: add 'Remove Vault from List' and 'Restore Getting Started Vault' commands
- StatusBar: add X button per vault item in vault menu dropdown
- 25 new tests covering removal, restore, edge cases, and command palette

-Task: pencil-ui-design-light-mode
-Summary: Verified all 115 top-level frames in ui-design.pen have theme:{Mode:Light}. No remaining before-variant frames found (only legitimate state-transition labels). No duplicate frames detected. Visual screenshots confirm correct light-mode rendering. Previous commit 165cc0e already applied theme to 25 dark-mode frames and removed 2 before variants.

+## Keyboard-First Principle (mandatory for every new feature)
+
+Every feature must be reachable via keyboard. This is both a UX requirement and a QA requirement — Brian tests the native app using keyboard only (osascript key events, no mouse).
+
+**Before marking any task done:**
+- Can the feature be triggered/used without touching the mouse?
+- If it requires clicking a button, add a command palette entry or keyboard shortcut
+- Document the shortcut in the command palette or menu bar
+
+**If you add UI that is only reachable by mouse**, you must also add a keyboard path (command palette entry, shortcut, or Tab-navigable focus). No exceptions.

+/// Content for the AGENTS.md file written to the vault root.
+/// This file has no YAML frontmatter — it is a convention file for AI agents,
+/// not a vault note. The vault scanner will still pick it up as a regular entry.
+const AGENTS_MD: &str = r#"# AGENTS.md — Vault Instructions for AI Agents
+
+This is a [Laputa](https://github.com/refactoring-ai/laputa) vault — a folder of markdown files with YAML frontmatter that form a personal knowledge graph.
+
+## Structure
+
+Files are organized in folders by type:
+
+| Folder | Type | Purpose |
+|--------|------|---------|
+| `note/` | Note | General-purpose documents, research, meeting notes |
+| `project/` | Project | Time-bounded efforts with clear goals |
+| `person/` | Person | People — colleagues, collaborators, contacts |
+| `topic/` | Topic | Subject areas that group related notes |
+| `responsibility/` | Responsibility | Long-running duties with KPIs |
+| `procedure/` | Procedure | Recurring workflows (weekly, monthly) |
+| `event/` | Event | Something that happened on a specific date |
+| `quarter/` | Quarter | Time containers (e.g. 24Q1) |
+| `measure/` | Measure | Trackable metrics tied to responsibilities |
+| `target/` | Target | Time-bound goals for a measure |
+| `type/` | Type | Type definitions — icon, color, ordering |
+
+Custom folders are valid — the folder name becomes the type (capitalized).
+
+## Frontmatter
+
+YAML frontmatter between `---` delimiters defines metadata:
+
+```yaml
+---
+Is A: Project
+Status: Active
+Owner: "[[person/jane-doe]]"
+Belongs to: "[[quarter/24q1]]"
+Related to:
+  - "[[topic/growth]]"
+  - "[[note/research-findings]]"
+---
+```
+
+### Standard fields
+
+| Field | Purpose |
+|-------|---------|
+| `Is A` | Entity type (usually inferred from folder) |
+| `Status` | Active, Done, Paused, Archived, Dropped |
+| `Owner` | Person responsible (wikilink) |
+| `Belongs to` | Parent relationship(s) |
+| `Related to` | Lateral associations |
+| `Cadence` | For Procedures: Weekly, Monthly, etc. |
+| `aliases` | Alternative names for wikilink resolution |
+
+### Custom fields
+
+Any YAML field containing `[[wikilinks]]` becomes a navigable relationship:
+
+```yaml
+Has Measures: ["[[measure/revenue]]", "[[measure/churn]]"]
+Resources: "[[note/api-docs]]"
+```
+
+## Wikilinks
+
+Connect notes with double-bracket syntax:
+
+- `[[note/my-note]]` — link by path
+- `[[My Note Title]]` — link by title or alias
+- `[[note/my-note|display text]]` — link with custom display text
+
+Wikilinks work in both frontmatter values and markdown body. Backlinks are computed automatically — linking A to B makes B show a backlink to A.
+
+## Type definitions
+
+Files in `type/` define entity types and control how they appear in the sidebar:
+
+```yaml
+---
+Is A: Type
+icon: rocket-launch
+color: purple
+order: 1
+---
+```
+
+Available colors: red, purple, blue, green, yellow, orange. Icons are Phosphor names in kebab-case.
+
+## Conventions
+
+- First `# Heading` in a file becomes its title
+- One entity per file
+- Filenames use kebab-case: `my-note-title.md`
+- Type is inferred from parent folder if not set in frontmatter
+- Relationships are bidirectional via automatic backlinks
