chore(privacy): remove identity/locale signals and dangling private-doc refs

Found by an actual read-through of every 1.1/1.2 file, not keyword search:

- src/utils.ts, src/view/chart.ts, esbuild.config.mjs: comments/code named
  a specific timezone (CEST), keyboard layout (Swedish), and locale code
  (sv-SE) used only for its date-format side effect — three independent
  signals triangulating toward the same nationality. Genericized all three;
  esbuild.config.mjs now formats the build timestamp manually instead of
  depending on any locale string at all.
- main.ts, src/view/table.ts, src/view/toolbar.ts: "iPhone"/"iCloud"
  framed as the author's own device/sync setup — genericized to "mobile"/
  "sync".
- main.ts, src/inline-view.ts, src/travel-data.ts, src/travel-view.ts:
  dangling "see handoff"/"HANDOFF" references to handoff.md, which is
  gitignored and not part of the public repo. Replaced each with a
  self-contained inline explanation instead of a pointer nobody can follow.
- docs/architecture.md: "Built for the author's book library and habit
  tracking" softened to describe original use case without first-person
  ownership framing.
- docs/dev-workflow.md: the project-tree diagram was stale (referenced
  test-mobile-dashboards.mjs and xlsx-to-csv-roundtrip.mjs, both long gone)
  and garbled (a cut-off local/ bullet with a "hardcoded-path caveat"
  aside). Rewritten to match the actual current file list.

Tests: 115 passed, 0 failed. Typecheck clean. Build unaffected.
