Logic:

Internationalization (I18n) - Translations:
- Add missing keys: notebooks.archived, common.note/insight, accessibility keys
- Add specific keys: sources.allSourcesDescShort, transformations.selectModel
- Add singular/plural keys: podcasts.usedByCount_one/other, common.note/notes
- Add common.created/updated with {time} placeholder

Internationalization (I18n) - Usage:
- SourcesPage: use allSourcesDescShort instead of string splitting
- TransformationPlayground: use navigation.transformation and selectModel
- CommandPalette: use dedicated keys instead of string concatenation
- GeneratePodcastDialog: fix zh-TW date locale handling
- NotebookHeader: correctly interpolate {time} placeholder
- TransformationCard: use common.description instead of undefined key
- ChatPanel/SpeakerProfilesPanel: implement proper pluralization
- SystemInfo: correctly interpolate {version} placeholder
- LanguageLoadingOverlay: use t.common.loading instead of hardcoded string
- MessageActions: use specific error key cannotSaveNoteNoNotebook

Other:
- Fix SessionManager.tsx exhaustive-deps warning

* fix: remove duplicate locale keys and add missing zh-CN translations

- en-US: remove duplicate loading key (line 59) and addNew key (sources)
- zh-CN: remove duplicate common keys (loading, note, insight, newSource, newNotebook, newPodcast)
- zh-CN: remove duplicate accessibility.searchNotebooks key
- zh-CN: remove duplicate sources.addNew key
- zh-CN: remove duplicate navigation.transformation key
- zh-CN: add missing usedByCount_one and usedByCount_other keys in podcasts
- zh-TW: remove duplicate common keys (loading, note, insight, newSource, newNotebook, newPodcast)
- zh-TW: remove duplicate accessibility.searchNotebooks key
- zh-TW: remove duplicate sources.addNew key

* docs: remove info.md

* fix: remove duplicate notebook keys and unused ts-expect-error

- zh-CN: remove duplicate notebooks keys (archived, archive, unarchive, deleteNotebook, deleteNotebookDesc)
- zh-TW: remove duplicate notebooks keys (archived, archive, unarchive, deleteNotebook, deleteNotebookDesc)
- GeneratePodcastDialog: remove unused @ts-expect-error directive

* fix(a11y): fix unassociated labels in search page

- Replace <Label> with role='group' + aria-labelledby for search type section
- Replace <Label> with role='group' + aria-labelledby for search in section
- Follows WAI-ARIA best practices for labeling form field groups

* fix(a11y): fix unassociated labels across multiple components

- search/page.tsx: use role='group' + aria-labelledby for search type and search in sections
- RebuildEmbeddings.tsx: use role='group' + aria-labelledby for include checkboxes
- TransformationPlayground.tsx: replace Label with span for non-form output label

* chore: revert to npm stack and ensure i18n compatibility

* chore: polish zh-TW translations for better idiomatic usage

* fix: resolve linter errors (ruff import sort, mypy config duplicate)

* style: apply ruff formatting

* fix: finalize upstream compliance (Dockerfile.single, i18n hooks, docker-compose)

* style: polish strings, fix timeout cleanup, and improve test mocks

* fix: use relative imports in test setup to resolve IDE path errors

* perf(docker): optimize build speed by removing apt-get upgrade and build tools

- Remove apt-get upgrade from both builder and runtime stages (saves 10-15 min each)
- Remove gcc/g++/make/git from builder (uv downloads pre-built wheels)
- Add --no-install-recommends to minimize package footprint
- Keep npm mirror (npmmirror.com) for faster frontend deps
- Add npm registry config for reliable China network access

Also includes:
- fix(a11y): add missing labels and aria attributes to form fields
- fix(i18n): add 2s safety timeout to LanguageLoadingOverlay
- fix(i18n): add robustness checks to use-translation proxy

Build time reduced from 2+ hours to ~34 minutes (~70% improvement)

* fix(a11y): resolve 16 form field accessibility warnings in notebook and podcast pages
