App config modules - Otter Shell

One src/*.zig file per app or daemon, each exporting a Config struct (plus nested widget configs).

`launcher`	`otter-launcher`	Appearance, sort order, keybinds
`dock`	`otter-dock`	Workspace-only, not in metapackage
`notifications`	`otter-notifications`	Timeout, position, styling
`wallpaper`	`otter-wallpaper`	Mode, paths, transitions
`osd`	`otter-osd`	Volume/brightness overlay
`jade`	`otter-jade`	Layer-shell pet
`logout`	`otter-logout`	Power menu overlay
`overview`	`otter-overview`	Workspace overlay: axis, card scale, captures, empty-workspace policy
`polkit`	`otter-polkit`	Auth dialog chrome
`lock`	`otter-lock`	Colors, layout, PAM, focus output
`greeter`	`otter-greeter`	Login UI tokens
`idle`	`otter-idle`	Idle timeouts and dim
`monitor`	`otter-monitor`	`refresh_interval_seconds` (1..3600)
`transcribe`	`otter-transcribe`	Model and device prefs
`term`	`otter-term`	Font, scrollback, palette
`theme_gen`	`otter-theme-gen`	Generation options
`assist`	`otter-assist`	Backend settings (`otter-shell-extras`)
`clicker`	`otter-clicker`	Interval, button, click type, fixed position
`search`	`otter-search`	Roots, budgets, content indexing, `max_results`

Monitor example

pub const Config = struct {
    refresh_interval_seconds: u16 = 3, // clamped 1..3600 at runtime
};

Assist example

pub const Backend = enum { cpu, vulkan };

pub const Config = struct {
    backend: Backend = .vulkan,
    vulkan_device: i32 = -1,
    idle_seconds: u32 = 120,
    knowledge_enabled: bool = true,
    web_enabled: bool = true,
    web_always_allow: bool = false,
    weather_enabled: bool = true,
    desktop_search_enabled: bool = true,
    desktop_search_always_allow: bool = false,
    pika_search_url: []const u8 = "https://search.pika-os.com/search?lang=en",
    knowledge_index_dir: []const u8 = "/usr/lib/otter-assist/indexes",
    max_tool_calls: u8 = 4,
    max_web_searches: u8 = 2,
};

Search example

pub const Config = struct {
    enable_xdg_user_dirs: bool = true,
    enable_home_config: bool = true,
    enable_home_shallow: bool = true,
    content_indexing: bool = true,
    max_content_file_bytes: u64 = 10 * 1024 * 1024,
    cache_budget_max_bytes: u64 = 256 * 1024 * 1024,
    max_files_per_root: u64 = 75_000,
    max_results: u32 = 10, // daemon clamps to 50
    root: conf.Dynamic(Root, "root") = .{},
};

Small tool configs (calc, emoji, clip, etc.) live in otter-tools-core app_configs.zig, not here.
