theseus/preload.js
Local Dev 0117986657 Theseus: add-on framework MVP + Notepad reference add-on
New subsystem for extending Theseus with folders on disk. Each add-on
lives at <userData>/addons/<id>/ with an addon.json manifest and a
CommonJS entry that exports activate(api). Nothing about a private
add-on ships in the public installer - drop the folder, restart, it's
live. Bundled reference add-ons ride in the packaged app under
resources/bundled-addons/ and are seeded into <userData>/addons/ on
first boot; the framework treats seeded and drop-in add-ons the same.

Files:
- addons-host.js         Loader + api.registerSidebarPanel() + per-
                         addon storage on <userData>/addons-data/.
                         Kept at the CommonJS-scoped top level (lib/
                         is ESM-scoped via its own package.json).
- sidebar-preload.js     Runs in every sidebar panel. Exposes
                         window.silentmode.storage.{get,set,all} +
                         onVisibility. Main-side handlers derive the
                         add-on id from the sender file:// URL, so a
                         panel can only touch its own store.
- bundled-addons/notepad/  Reference add-on: addon.json, index.js,
                         note.html. Autosaving textarea with char /
                         word count.

main.js:
- Extension point: sidebar-panel. One right-anchored WebContentsView
  (SIDEBAR_W=340) hosts the current panel; layout() shrinks the tab
  views by the sidebar width when visible. First registered panel
  wins for MVP; picker for multiple panels lands later.
- initAddons() at app.whenReady(): seedBundledAddons, then
  AddonHost.discoverAndActivate.
- IPC surface: sidebar-toggle / sidebar-open / sidebar-close /
  sidebar-state, addons-list / addons-set-enabled / addons-reveal /
  addons-open-dir / addons-reload, and origin-gated
  addon-storage-get/set/all.
- Settings gains `disabledAddons: []` — off-toggled ids persist and
  the loader honours them without a restart (discoverAndActivate
  runs again on toggle).

chrome.html: toolbar sidebar-toggle button, hidden until at least one
add-on has registered a sidebar panel.

settings.html: new "Add-ons" section under privacy. Lists installed
add-ons with icon / name / version / description / capabilities;
per-add-on enable/disable toggle + Show folder button; page-level
Reload and Open add-ons folder buttons; warning note about the trust
model.

package.json: build.files gains sidebar-preload.js + addons-host.js.
extraResources gains bundled-addons/ so the packaged app carries the
reference notepad for the first-boot seed.

Verified: `npm start` boots, addons-host discovers the notepad,
activates it, registers one sidebar panel. Log confirms
"1 installed, 1 enabled, 1 sidebar panels". Actual sidebar rendering
+ notepad UI need clicked-through validation on a real install.

Not shipped yet - deploy still blocked on the fail2ban VPS SSH ban.
Ships as 0.2.0 once SSH clears (this is a new subsystem, not a fix).
