docs: update README with feature overview and module structure

Add Java extension support and configure multiple JDK runtimes.
Introduce a wrapped VS Code package that includes JDK 25 in the PATH
to support the Red Hat Java language server.

Switch from using `programs.vscode.userSettings` to a manually managed
`settings.json` file via `home.file`. This allows the settings file to
be writable by external tools like `kilo-code` at runtime while
preserving them across Nix configuration switches by using `force = false`.

 Each machine: `modules/hosts/<name>/default.nix` → `nixosConfigurations.<name>`, real config in `*Configuration` + optional `_private/` and `_services/`.
 
+## Features at a glance
+
+- **Users catalog** — one catalog in `modules/system/users.nix`, pick who exists on a host with `chiasson.users.enabled = [ "example" ]`, override per host. Home Manager wires itself from the same list.
+- **SSH + Bitwarden (rbw) keys** — one ed25519 keypair per catalog user, private key in Bitwarden, public key in `modules/ssh/inventory.nix`. Outbound SSH uses a `.pub` filter against the rbw agent; inbound `authorized_keys` are generated from the same inventory. [Full wiring in conventions.md](./conventions.md#ssh-model).
+- **Wisdom modules** — Home Manager slices in `modules/wisdom/` auto-catalog via `lib.wisdomCatalogExtraModules` (defined in `modules/desktop/options.nix`). The baseline `wisdom` module handles git identity + shared tools; all other `wisdom*` exports are pulled in once per user through `desktopHomeBase` → `chiasson.users.extraModules.olivier`. Hosts only flip `chiasson.home.<category>.<slice>.enable` — no manual imports in `home.nix`. Categories include `apps` (spotify, discord, localsend), `browsers` (chrome, edge, zen, …), `editors` (cursor, vscode, obsidian, …), `shells` (bash, fish, oh-my-posh, yazi), `desktop` (gtk-qt-theming, screenshot), and `terminals` (kitty). Trivial single-package slices can be written with the `lib.wisdomSlice` helper instead of repeating the `root`/`cfg` + `mkIf` boilerplate.
+- **Wallpapers from a dedicated repo** — `modules/desktop/wallpapers.nix` pins `inputs.wallpapers` into the store and exposes it as `CHIASSON_NIX_WALLPAPERS` and `/etc/wallpapers`. Override `chiasson.desktop.wallpapers.source` if needed.
+- **Private host data** — import-tree skips `_private/` globally, so machine-only files (firmware quirks, display configs, service tweaks) live next to the host module without leaking elsewhere.

Several such slices may share one `simple.nix` in their category dir (each still exporting its own `wisdom*` module), rather than one file per slice.
 
 **Derivations:** `let` inside a fragment, or `flake.packages` / `flake.lib` — not a bare `mkDerivation` file import-tree will try to load.
