chore(bundle): add bundle-size audit + snapshot inventory

Browse source 
scripts/audit-bundle.mjs reads `.svelte-kit/output/client/_app/immutable`
after a prod build and reports:
  - Total size + category breakdown (entry / nodes / chunks / workers /
    assets).
  - Top N JS files with content heuristics (transformers.js, zxcvbn,
    tiptap, pdf-lib, swissqrbill, rrule, suncalc, Phosphor icon paths,
    Vite __vite__mapDeps metadata, etc).
  - Route mapping for `nodes/*.js` by parsing the server manifest's
    `leaf:` entries, so node 118 is identified as /(app)/invoices/[id].
  - ⚠ flag on chunks/ ≥ 200 KB (shared, potentially eager).

Current snapshot (docs/optimizable/bundle-analysis.md):
  entry   92 KB  |  nodes   2.77 MB  |  chunks   5.59 MB
  workers 22.3 MB (ONNX WASM, lazy)  |  total   31.8 MB

Already healthy:
  - 92 KB entry (no critical-path bloat).
  - 22 MB transformers.js WASM is worker-scoped — only fetched on first
    /llm-test or memoro voice use.
  - zxcvbn (1.25 MB combined dict + keyboard graphs) correctly behind a
    dynamic import in PasswordStrength.svelte.

Follow-up opportunities logged:
  1. /invoices/[id] = 534 KB — split swissqrbill + pdf-lib via dynamic
     import.
  2. @mana/shared-icons = 317 + 149 KB SVG path chunks — migrate to
     tree-shakable per-icon imports or lazy-load.
  3. Root (app) layout = 260 KB — check for module bleed into shared
     shell.

Report-only. Run with `pnpm run audit:bundle`.
