feat(theme-selector): magit and elfeed bespoke previews (tier-3 phase 5)

I added renderMagitPreview and renderElfeedPreview. The magit one is a status buffer: head and branch lines, an untracked section, a diff hunk with context, removed, and added lines, and recent commits with hashes, authors, and a keyword and tag. The elfeed one is a search list: the filter line, dated entries with feed, unread and read titles, and tags, plus log lines colored by level. The preview pane dispatches to each app's bespoke renderer, the generic fallback covers everything else, and the pane label now names the app and says whether the preview is bespoke or generic.

 *** 2026-06-08 Mon @ 02:27:51 -0500 Phase 4 — org preview landed
 Added =renderOrgPreview()=: a mock org document painted live from the org package faces (title, headings with heights, TODO/DONE, tag, scheduled date, property drawer, inline code/verbatim, link, checkbox, quote, src block, header-row table). The preview pane dispatches on the app's preview key; org-mode gets this, others keep the generic list. Verified: node, headless screenshot, self-test PASS.

-Bespoke mocks: a magit status buffer and an elfeed search list, live from their faces. Verify: screenshot. Fidelity to Manual testing. Spec phase 5.

 *** TODO [#B] Phase 6 — generated all-package inventory :solo:
 Build step queries Emacs for installed packages' faces grouped by package, writes a data file =generate.py= embeds; the dropdown then lists every package with an editable table + a labeled generic fallback preview. Verify: data file generates, dropdown lists packages, a fallback package edits and round-trips. Spec phase 6.
