refactor(wisdom): decentralize module defaults and update conventions

Browse Source 
Move Home Manager module defaults from a centralized `desktop-home-defaults.nix`
file into their respective `wisdom` slices. This change aligns with the
updated documentation regarding module ownership, where defaults live
with the option that owns them rather than in a shared defaults file.

Additionally, update `docs/conventions.md` to reflect this new pattern for
defining `mkEnableOption` defaults and move base git/encryption
configurations into the core `wisdom` module.

- Delete `modules/hosts/desktop-home-defaults.nix`
- Update `modules/wisdom/default.nix` to include shared git and package defaults
- Add `default = ...` to `mkEnableOption` in various `wisdom` modules
- Update `docs/conventions.md` with new HM slice guidelines

**New NixOS leaf:** export `flake.nixosModules.whatever`, wire from `system/default.nix` or `desktop/default.nix` if it's global, or only from a host `configuration.nix` if it's not. `nix flake check`. Git-add new paths if eval uses the git tree.
**New HM slice:** add `modules/wisdom/.../foo.nix` exporting `flake.homeManagerModules.wisdomFoo` (import-tree picks it up; `wisdomCatalogExtraModules` includes every `wisdom*` export except `wisdom` / `wisdomShellBash`). Gate packages on `chiasson.home.*.enable`, set `mkDefault true` in `desktop-home-base.nix` if shared, or `enable = true` in a host `home.nix`. Upstream HM deps stay imported unconditionally — use `mkIf` on `cfg.enable` for config (never `config`-dependent `imports`; that recurses).

Gate packages on `chiasson.home.*.enable`, and set the slice's own `enable` default (`mkEnableOption "…" // { default = true/false }`) in that same module — defaults live with the option that owns them, not in a shared defaults file. Hosts flip toggles in `home.nix`. Upstream HM deps stay imported unconditionally — use `mkIf` on `cfg.enable` for config (never `config`-dependent `imports`; that recurses).
**Derivations:** `let` inside a fragment, or `flake.packages` / `flake.lib` — not a bare `mkDerivation` file import-tree will try to load.
