LutrisProvider reads the local pga.db (rusqlite, read-only/immutable so a running Lutris can't block us) → installed games, launch via `lutris lutris:rungameid/<id>`, cover art from Lutris's on-disk cache inlined as data: URLs (no public CDN keyed by a stable id, unlike Steam/Heroic). HeroicProvider parses Heroic's store_cache JSON — legendary/gog/nile = Epic+GOG+Amazon in one provider — installed-only with an install-dir existence cross-check (works around Heroic's gog is_installed bug #2691), free public CDN cover art, launch via `heroic --no-gui heroic://launch?...` (the single-instance-Electron gamescope-escape caveat is documented; needs live confirm). New command_for arms (lutris_id digits-guard, heroic runner+appName-guard) + both providers wired into all_games(); everything Linux-gated (the launchers are Linux-only), so the Windows/macOS host build is unaffected. Deps rusqlite (bundled SQLite, no system dep) + base64 added to the Linux target only. Unit tests with sqlite/json fixtures (installed-only filtering, CDN-art mapping, launch guards); live `library` enumeration returns [] gracefully on a box without the launchers.

//! Game library (plan: "surface the user's games"). A small adapter layer over the *stores*
|
||
//! installed on the host — today **Steam** (read from local files, no API key) and a
|
||
//! user-curated **custom** store (CRUD'd via the management API / web console). Every store
|
||
//! produces the same [`GameEntry`], so a client renders one uniform grid and never has to know
|
||
//! which launcher a title came from. Future stores (Heroic/Epic, GOG, Lutris, EmuDeck) are just
|
||
//! more [`LibraryProvider`]s.
|
||
//!
|
||
//! Artwork is keyed only by Steam appid against the public Steam CDN (no auth) — the client
|
||
//! fetches the posters directly. Custom entries carry user-supplied art URLs.
|
||
//!
|
||
//! This module is read-mostly metadata; *launching* a chosen title (mapping [`LaunchSpec`] onto a
|
||
//! gamescope session) is a later step — the launch hint is carried here so that wiring is trivial.
