CC One : anciennes versions à télécharger

Changed
- Workspace visual system rebuilt — the title bar grows taller on a card surface: the icon-only nav collapse moves to ≤1360px and at ≤760px the nav takes its own second row, so window controls and status stay reachable at every width. Every view opens with a page heading (title + one-line description, new trilingual strings) so page identity survives the collapsed bar. Typography lands a three-tier stack: headings prefer Bahnschrift, body text gains PingFang SC / Microsoft YaHei CJK fallbacks, mono is pinned to Cascadia Code. (#119)
- Dashboard grouped into headed sections — the card flow now reads under two semantic section headings (consumption sources / usage patterns), each with a description line; the 12-column grid classes move into the shared src/styles/workspace.css. (#119)
- Token hero rebuilt — CardHeader + a token-ledger color strip in the header, and the card now carries its own loading / error / retry states via QueryState (use-token-snapshot exposes isLoading / error / retry). (#119)
- Card system tightened app-wide — radius up to xl with reduced padding, interactive hover switches from shadow lift to border emphasis, and all usage cards unify on the CardHeader / CardTitle structure. (#119)
- Capsule switches standardized — the hand-rolled capsule toggles in the trend absolute/share switch, model distribution and session ranking are replaced by shadcn ToggleGroup. (#119)
- Stylesheet split — index.css extracts transcript typography (transcript.css) and workspace surfaces / grid (workspace.css). (#119)

Added
- The packaged binary is named "CC One" — tauri.conf.json now declares mainBinaryName explicitly, so the bundled executable ships as CC One, matching the app name, instead of the cargo output name cc-one (CC One.exe on Windows).
Fixed
- Gemini snippet preview no longer over-promises — an empty-value env key (e.g. KEY=) used to be listed as an importable snippet candidate even though extraction could never deliver it (the validator rejects empty values). "Which keys are shareable" now lives in a single decision roster that both the preview candidates and the extraction derive from, so Gemini's empty-value keys no longer appear as candidates.
Changed
- imported now counts items, not rows — the sync align report (startup log and settings-page toast) sums what each domain actually imported: new usage rows, imported peer session snapshots, provider entries written, device registrations loaded (wording updated in en/zh; ja was already neutral).
- Internal refactors, behavior intact — all fourteen architecture candidates landed, with 40 new tests pinning the invariants on production paths:
- Sync — the per-device JSON sync document (fault-tolerant read, byte-stable write, latest-wins merge) converges on a single synced_doc module, adopted by providers / groups / devices and pinned by byte-level golden tests; the sync domain list becomes data — a static DOMAINS table drives pull/push (adding a domain = adding a row).
- Providers — shareable-key decisions are single-sourced (preview candidates and extraction derive from the same roster); the three-state controlled merge (present → replace / absent → withdraw / unlisted → skip) becomes one shared primitive, and Gemini's "the whole settings.json top level is controlled" ruling is made explicit (merge behavior byte-identical); the provider-row UPSERT clock difference is typed as ProviderUpsertPolicy (local clock / author timestamp pass-through).
- Database — the three cross-cutting aspects of dimension aggregation (driver projection, composite-key predicates, bucket decoding) converge in aggregate_sql; usage_records' column list, bind and decode now live in one place with a compile-time length check; "which session columns ride git pushes" is explicit as PushTrack (the favorites track pushes, device-local fields never enter snapshots).
- Source parsing — per-line JSONL folding converges on one shared walker (1-based numbering / blank lines / skipped accounting single-sourced), with the two cursor semantics (claude/codex vs grok) explicit as two policies.
- Frontend — the transcript derive cluster moves to its own module; the token-bucket display roster (color order / key order) replaces four hand copies with a single BUCKET_DISPLAY; the five-dimension filter bar (time · source · model · project · device) becomes a shared FilterBar bound by both toolbars, dropping six date keys from the browser hook; page-edge stepping decisions become pure functions and the rename hook moves into session detail.
- Misc — post-change push sinks into the library domain entry (callers can no longer "change locally without pushing"); track/column magic strings become enums (bindings regenerated); "write then emit sessions_changed" is structurally fixed by two combinators; forget_device's is_self guard sinks into the domain entry.
