fix: centralize state defaults via lib/state-schema.nix

Kills a recurring bug class: state defaults previously lived in three
parallel places that drifted apart over time.

  - lib/state-schema.nix          (the canonical schema, referenced
                                   nowhere except a description string)
  - core/system/options.nix       (default = "..." clauses on options)
  - core/home/options.nix         (same, on home options)
  - core/home/state.nix           (`or "..."` fallbacks for state.json reads)

When `state.json` is missing a key, three files have to agree on the
fallback. They keep silently drifting:

  - The OOTB QA audit shipped fixes for this pattern.
  - Earlier this session, `chore: switch default theme summer-night → nord`
    fixed core/system/options.nix and core/home/state.nix — but missed
    core/home/options.nix, which still defaulted nomarchy.theme to
    "summer-night". Every consumer of the home option
    (features/default.nix, vscode.nix, waybar, hyprland, theme engine)
    resolved to the wrong theme when state.json was blank.

This change:

  - Imports lib/state-schema.nix into all three consumers and replaces
    every hardcoded default with `schema.<scope>.<key>`.
  - Fixes the lingering nomarchy.theme = "summer-night" home-side bug as
    a side-effect.
  - Touches roughly 25 literals across the three files.

Verified `nix flake check --no-build` passes and every centralized value
evaluates to the exact literal it previously had. Off-schema option-only
defaults (isLightMode, formFactor, cursor.*, iconsTheme, keyring.enable,
etc.) are left hardcoded — they have no state.json counterpart, so
there's no source-of-truth split to resolve.

Out of scope (follow-up):
  - Have installer/install.sh generate /mnt/etc/nixos/state.json from
    the schema instead of hardcoded JSON — would close the last
    split-brain surface (the installer can still drift from schema).

- _2026-05-18_ — Declarative-state defaults centralization. Made `lib/state-schema.nix` the single source of truth for every state-default that previously lived in three places (the schema itself, `core/system/options.nix` / `core/home/options.nix` `default = …` clauses, and `core/home/state.nix` `or …` fallbacks). Replaced ~25 hardcoded literals with `schema.<scope>.<key>` reads. Side-effect: fixed a lingering bug where `core/home/options.nix:theme` still defaulted to `"summer-night"` after the system-side was moved to `"nord"` — half the codebase's home option resolved to the wrong theme when state.json was missing/blank. `nix flake check --no-build` confirms zero semantic change for every other field. Doesn't touch the installer-written `state.json` (separate batch — needs schema → JSON generation).
