fix: use git ls-files --unmerged for reliable conflict detection

git diff --name-only --diff-filter=U only works during an active merge
(while MERGE_HEAD exists). When the vault has stale conflict state —
e.g. after a reboot — git diff returns empty, causing conflictFiles=[]
and making the StatusBar click handler, command palette entry, and
conflict resolver modal all non-functional.

Switch to git ls-files --unmerged which reads unmerged index entries
directly and works regardless of MERGE_HEAD state.

-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.

+# Laputa — Vision
+
+Laputa is a personal knowledge base where humans and AI agents collaborate as equals.
+
+---
+
+## Core principles
+
+### 1. The vault is the source of truth
+Everything lives in the vault as plain text files. Notes, relations, configuration, instructions — all Markdown with YAML frontmatter. No proprietary database, no hidden state. If you can open a terminal, you can read your vault. If you can write Markdown, you can modify it.
+
+### 2. Vault-native configuration
+Laputa configures itself through files inside the vault — the same files you write and read every day. There is no separate "settings app" or admin panel. If you want to change a theme, you edit a note. If you want to give instructions to an AI agent, you write a note. If you want to define a template, you create a note.
+
+This applies to:
+- **`_themes/`** — themes as notes with a YAML block in the body. Edit `_themes/dark.md`, see the colors change in real time.
+- **`AGENTS.md`** — instructions for AI agents. Write what you want them to know about your vault in plain language. They read it before acting.
+- **`_templates/`** — note templates per type. Create `_templates/event.md` and every new event starts from that structure.
+- **`_procedures/`** — recurring tasks as notes with a `schedule` frontmatter field.
+
+The principle: **if it can be expressed in frontmatter + Markdown, it doesn't need a UI**.
+
+### 3. Structure through types, not folders
+Notes have a `type` field. Types determine folders, icons, and colors — but the structure is defined by the data, not the filesystem hierarchy. You can query "all events in February" without knowing anything about folder layout.
+
+Relations between notes are expressed as frontmatter arrays: `people: [Marco, Sara]`. A wikilink `[[Marco]]` in the body navigates to the person note. The graph emerges from the data, not from a separate graph database.
+
+### 4. The file is the interface
+You can use Laputa's UI, or you can open a terminal. Or a text editor. Or Claude Code. They all operate on the same files. There is no difference between "the app" and "the vault" — the vault is the app.
+
+This is why Laputa has an MCP server: external agents get the same tools the in-app AI panel uses. The interface is a convenience, not a requirement.
+
+### 5. Humans and AI as collaborators
+Pulse — the activity feed — shows the history of the vault without distinguishing between human commits and agent commits. That's intentional. Laputa is designed to be a space where you and your AI agents work together, each contributing to the same knowledge base.
+
+The AI doesn't have a separate workspace. It works in yours.
+
+---
+
+## What Laputa is not
+
+- Not a todo app (though you can use it as one)
+- Not a note-taking app that syncs to the cloud (the vault is yours, sync however you want — git, iCloud, rsync)
+- Not a replacement for a terminal (power users will use both)
+- Not trying to abstract away git (git is a feature, not an implementation detail)
+
+---
+
+## The long game
+
+A vault that grows with you for years. Events, people, projects, thoughts — all interconnected, all version-controlled, all accessible to any tool that can read a file.
+
+Ten years from now, your vault should still be readable. Plain text is forever.

+/// 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
