feat(theme-selector): add relative height to the package-face schema

I folded a relative height field into the tier-3 spec and brought Phase 1's schema in line. A face's height is a float multiplier off the base font (1.3 is 1.3x the running font, never a point size), so it stays portable across fonts and machines, and it's omitted from export at 1.0. The font family itself stays in font-config.el, where it belongs; the theme owns only relative size.

Height is read straight off the face and does not cascade through inherit, because Emacs multiplies float heights along an inherit chain and headings should each size off the body, not compound off the level above. The org starter now seeds heading heights and the fixed-pitch inherits that keep code and tables monospace under variable-pitch prose. The self-test gained a height assertion and still reports PASS.

 Package-specific face editing in the theme-selector: org/magit/elfeed bespoke (complete face tables + live previews) plus a generated all-package inventory so every installed package is themeable. Spec is Ready, all opens resolved: [[file:docs/design/theme-selector-package-faces-spec.org][docs/design/theme-selector-package-faces-spec.org]]. Phases below run in dependency order; phases 1-5 deliver the three high-value apps, phase 6 opens the long tail, phase 7 documents. The =theme.json= -> =dupre-*.el= converter (Elisp) is a separate downstream task.
 
 *** 2026-06-08 Mon @ 00:17:41 -0500 Phase 1 — package state + schema landed
-Added =APPS= (org starter) and =PKGMAP= ({app:{face:{fg,bg,bold,italic,inherit,source}}}), pure helpers (=seedPkgmap= / =packagesForExport= / =mergePackagesInto=), and wired export/import for the =packages= key with old-JSON compat. No UI yet (Phase 3). Verified: node-check, plus a guarded =#selftest= harness (headless Chrome) confirming seed->export->import round-trip, old-JSON merge, and inherit/source survival — all PASS.

 *** TODO [#B] Phase 2 — curated app data (org/magit/elfeed) :solo:
 Complete own-defface face lists + seeded defaults modeling org's real inherit cascade, for org (incl. org-agenda), magit, elfeed, in =APPS=. Pure data. Verify: each app lists its full grouped set. Seeded-default aesthetics go to Manual testing. Spec phase 2.
