feat(editor): Remember previous location + Command Palette (⌘K)

Remember previous location (Preferences): persists collection +
document chain (or Home) to UserDefaults on every navigation change,
gated on the preference. Restored once per launch by resolving the
stored IDs back through the API, stopping at the first failure
(deleted doc, offline, etc.) rather than aborting the whole restore —
a partial chain beats falling all the way back to Home. Cleared on
sign-out so switching accounts can't restore a stale location.

Command Palette (new Settings → Editor section, not synced to
Outline): ⌘K opens a floating overlay, arrow-key/click navigation,
Enter or click to select. Always searches locally, never a
per-keystroke network request:
- Lightweight (default): live listCollections + listViewedDocuments
  fetch once on open.
- Full Workspace (opt-in, requires Full Local Sync on): reads
  CachingOutlineAPIClient's local cache directly — zero network calls,
  includes nested sub-documents now that Full Local Sync actually
  caches them (see the paired OutlineKit commit).

Fixed through live testing, in order found:
- Focus: the search field wasn't reliably first responder the instant
  ⌘K opened it (also the likely source of several AppKit
  CA-transaction console warnings) — added a short delay before
  focusing.
- Full Workspace "no results": was sequential one-collection-at-a-time
  fetching before the cache-read redesign: withTaskGroup made it
  concurrent, and reading from the cache instead of the network made
  it moot.
- Arrow keys not moving selection: .onKeyPress was on the outer card,
  but the focused TextField swallowed the events before they could
  bubble up. Moved the handlers directly onto the TextField.
- Search ranking: exact-phrase-only matching meant a title like "Test
  Plan Document" never matched a "test document" query at all
  (filtered out, not just ranked low), making it look like collections
  always won. Added a fallback tier: every word of a multi-word query
  present anywhere in the title still matches, ranked below
  exact/prefix/substring hits.
- foregroundStyle(.secondary vs .orange) ternary: HierarchicalShapeStyle
  vs Color type mismatch, fixed with AnyShapeStyle on both branches.
