docs: add ADR-0029, ADR-0030; update README index (guard — from commits 1ae1377, a59640)

The ResizeHandle div was not stretching to the full height of its flex
row parent, making it only interactive in the top portion. Adding
self-stretch (align-self: stretch) ensures it fills the complete cross-axis
height of the container, so the user can drag at any vertical position.

Fixes: Properties panel resize handle active area.

+title: "Domain command builder pattern for useCommandRegistry"
+status: active
+date: 2026-03-30
+---
+
+## Context
+
+`useCommandRegistry` was a 224-line "brain method" (CodeScene hotspot) that defined all command palette commands inline: navigation, note actions, git operations, view toggles, settings, type management, and filter controls. This monolithic structure scored 39 on CodeScene's complexity scale (target: ≤9.5 for hotspots), making it increasingly hard to add new commands without touching the central file.
+
+## Decision
+
+**Split command definitions into focused domain modules under `src/hooks/commands/`, each exporting a `build*Commands(config)` factory function. `useCommandRegistry` becomes a thin assembler that calls each builder and merges the results.** Domain modules: `navigationCommands`, `noteCommands`, `gitCommands`, `viewCommands`, `settingsCommands`, `typeCommands`, `filterCommands`. Shared types live in `commands/types.ts`; public API re-exported from `commands/index.ts`.
+
+## Options considered
+
+- **Option A** (chosen): Domain builder modules — each module owns its command shape and receives typed config. `useCommandRegistry` is pure assembly. All new files score 9.58–10.0. Downside: more files to navigate.
+- **Option B**: Split by file but keep one large hook calling sub-hooks — sub-hooks still need shared state passed down, similar coupling. No real complexity win.
+- **Option C**: Register commands imperatively via a global registry — decouples callers entirely. Downside: harder to trace, no TypeScript inference at the registration site, over-engineering for current scale.
+
+## Consequences
+
+- Adding a new command means editing the relevant domain module (e.g. `noteCommands.ts`) only, not touching the assembler.
+- Each domain module receives only the config it needs — explicit, typed interface, no hook dependency.
+- `useCommandRegistry` reduced from 224 lines to a thin assembler.
+- Pattern is consistent with the Rust commands/ module split (ADR-0030).
+- Re-evaluation trigger: if command count grows to the point where the assembler itself becomes a complexity hotspot.

+title: "Rust commands/ module split by domain"
+status: active
+date: 2026-03-30
+---
+
+## Context
+
+`src-tauri/src/commands.rs` grew to 937 lines as Tauri command handlers accumulated for vault CRUD, git/GitHub sync, AI, system, and window operations. All commands shared a single file with no domain separation, making it hard to navigate, review, and extend. The file was a CodeScene hotspot dragging down overall code health.
+
+## Decision
+
+**Replace `commands.rs` with a `commands/` module split by domain: `vault.rs`, `git.rs`, `github.rs`, `ai.rs`, `system.rs`, and `mod.rs` (shared utilities + re-exports).** Each file owns the Tauri command handlers for its domain and the `#[cfg(desktop)]` / `#[cfg(mobile)]` stubs for platform-conditional availability. `mod.rs` is kept thin (≤100 lines) with no command logic — only re-exports and shared helpers (`expand_tilde`, `parse_build_label`).
+
+## Options considered
+
+- **Option A** (chosen): Domain-based module split — mirrors the TypeScript `hooks/commands/` pattern (ADR-0029). Each file is independently reviewable and scores well on code health. Downside: more files to navigate.
+- **Option B**: Split by platform (`desktop.rs`, `mobile.rs`) — aligns with `#[cfg(...)]` guards but mixes domain concerns. Harder to find a specific command.
+- **Option C**: Keep monolith but add section comments — zero file-count cost, but doesn't solve complexity or reviewability.
+
+## Consequences
+
+- `github.rs` separates GitHub OAuth/API commands from git sync commands (`git.rs`), matching the underlying Rust module split (`github/` vs `git/`).
+- Platform stubs (`#[cfg(mobile)]` error returns) live alongside the desktop implementation in the same domain file.
+- `mod.rs` re-exports all command functions so `lib.rs` `invoke_handler!` registration is unchanged.
+- New Tauri commands go into the appropriate domain file; if no domain fits, create a new one rather than putting it in `mod.rs`.
+- Re-evaluation trigger: if a single domain file (e.g. `vault.rs`) itself grows beyond ~300 lines and becomes a hotspot.
