chore(release): bump v4.7.1 → v4.8.0; Prettier pass on overnight-session files

12 commits on master since v4.7.1 baseline, taking tests 524 → 914 across
27 new suites. This commit:
- Bumps package.json + README version to v4.8.0 (additive features → semver minor)
- Applies Prettier formatting to all files touched during the overnight
  session so release build is reproducible from a clean repo

New in v4.8.0:
- PDF encryption close-out (D1)
- KaTeX rendering test coverage
- Autosave buffer + crash recovery banner
- Daily notes + workspace search + doc-aware Q&A
- Search sidebar panel + Ask mode
- Status bar: word count, reading time, Flesch-Kincaid grade
- Footnote hover preview
- Smart paste (URL → link, CSV/TSV → table)
- Daily notes menu item + sidebar panel + Q&A deep-link
- Daily templates gallery
- Pluggable DocQA engine (TF-idF default + lazy neural embeddings)
