Harden settings: split breadcrumbs secrets, typed exec, new panels

Load and save Wi-Fi networks in networks.toml (0600) instead of writing
PSKs back into breadcrumbs.toml. The password field is write-only.

Replace the generic argv runner with typed bakery/pacman/fwupd commands
and set a real Tauri CSP. Add Lock, Screenshots, Monitors, and Help
panels. Pin bread-theme and bread-utils to bread-ecosystem v0.7.1.
bread-screenshots is not on that tag, so --screenshot calls grim
locally. bakery.toml lists webkitgtk-4.1 deps; README/CLAUDE.md match
Tauri 2 + Svelte 5 and single-trunk main.

+# CLAUDE.md — Repo hygiene
+
+Scope: this file covers *repo hygiene* — branching, remotes, CI, cleanup. It is not project documentation.
+
+This repo is a **Tauri 2 + Svelte 5** settings app, bakery-distributed. It follows the branch/release workflow in `CONTRIBUTING.md` — read and follow it for any git, branch, or release work here (the single-trunk model, `feature/x`/`fix/x` branch naming, how RC tags work, etc). Don't improvise a different workflow. The short version: there is one long-lived branch, `main` — no `dev` or `beta` branch exists. `main` auto-publishes a bakery **dev-track** build on every push. "Beta" and "stable" are both just tags, not branches: push a `vX.Y.Z-rc.N` tag to publish a beta-track build, push a plain `vX.Y.Z` tag to cut the signed stable release. "Freezing" for stabilization means pausing pushes to `main`, not moving a branch.
+
+This is not a GTK4 app. There is no `package.yml` pacman workflow here; bakery is the distribution channel.
+
+## Layout
+
+- `frontend/` — Svelte 5 + SvelteKit (static adapter) + TypeScript
+- `src/` — Tauri 2 Rust crate (`bos-settings`). Commands live in `src/src/commands/`.
+- Config edits are non-destructive (`toml_edit` / `bread_utils::tomlcfg`) except for JSON files that have no comments to preserve.
+
+## Remotes
+
+- `origin` — Forgejo (`git.breadway.dev` via Hestia, SSH) — authoritative.
+- `github` — GitHub mirror. Push `origin` only; the github remote auto-mirrors.
+
+## CI
+
+- `dev-release.yml` — push to `main`.
+- `rc-release.yml` — `vX.Y.Z-rc.N` tags.
+- `release.yml` — other `v*` tags (signed stable).
+
+No build/lint/test CI runs on ordinary commits or PRs to `main` beyond the dev-track workflow above.
+
+## Don't
+
+- Don't commit `frontend/node_modules`.
+- Don't embed credentials in remote URLs — SSH or a credential helper only.
+- Don't write Wi-Fi passwords back into `breadcrumbs.toml`. Networks live in `~/.config/breadcrumbs/networks.toml` (0600).
+- Don't expose a generic argv runner to the webview. Streaming updates are typed commands (`bakery_update`, `pacman_system_update`, `fwupd_*`).

 # bos-settings
 
-System settings app for [BOS (Bread Operating System)](https://git.breadway.dev/Breadway/bos) — GTK4, configures every bread\* app's config plus core system settings (network, sound, power, users, firewall, snapshots, packages, AUR, firmware, Hyprland display/appearance/autostart) non-destructively.
+System settings app for [BOS (Bread Operating System)](https://git.breadway.dev/Breadway/bos) — Tauri 2 + Svelte 5. Configures every bread\* app's config plus core system settings (network, sound, power, users, firewall, snapshots, packages, AUR, firmware, Hyprland display/appearance/autostart) non-destructively.
 
-Split out of the `bos` repo into its own repo so a bos-settings release doesn't require a BOS ISO release, and vice versa. Distributed via `bakery` — see `bread-ecosystem`'s `CONTRIBUTING.md` for the dev/beta/stable track workflow shared across the bread ecosystem.
+Distributed via `bakery`. There is one long-lived branch, `main`; see `CONTRIBUTING.md` for the single-trunk / RC-tag release model shared across the bread ecosystem.
 
 ## Building
 
+The Svelte frontend lives in `frontend/`, the Rust backend in `src/` (this repo's crate is not named `src-tauri`). `cargo tauri build` runs the frontend build hook; a plain `cargo build` does not.
+
 ```bash
-cargo build --release
+cd frontend && npm ci && npm run build
+cd ../src && cargo build --release
+```
+
+Dev (Vite + `cargo tauri dev`):
+
+```bash
+cd src && cargo tauri dev
 ```
 
 ## Packaging / releasing
 
-Bump `Cargo.toml`'s version, tag `vX.Y.Z`, push the tag to both remotes — `.forgejo/workflows/release.yml` builds and publishes to `dl.breadway.dev` (bakery) automatically. Pushes to `dev`/`beta` publish a dev/beta-track build the same way, no tag needed.
+Bump `src/Cargo.toml` (and `frontend/package.json`) version, then follow `CONTRIBUTING.md`: work lands on `main` via `feature/` / `fix/` branches (every push to `main` publishes a bakery **dev** build). Tag `vX.Y.Z-rc.N` for beta, `vX.Y.Z` for the signed stable release. Do not push to a `dev` branch — there isn't one.
