Download CodeWhale 0.8.50

Added
- Added a Windows NSIS installer release artifact and classroom/lab deployment checklist, harvested from #2045 for #1987. The release workflow now builds CodeWhaleSetup.exe from the canonical Windows binaries, and the installer adds/removes only the exact current-user PATH entry.
- Added deterministic session timestamps in session listings, receipt-export boundary docs, and current-model turn metadata for routed/auto sessions.
- Added exact AtlasCloud provider-hinted model ID pass-through for explicit vendor/model-id selections, harvested from #2569 without freezing a brittle provider catalog.
- Added Xiaomi MiMo speech/TTS support with a codewhale speech CLI command, tts tool alias, and config wiring for voice-design and voice-clone models, harvested from #2560.
- Added a three-zone immutable prefix diagnostic layer (FrozenPrefix Phase 2) that logs cache-prefix drift at debug level without blocking requests, harvested from #2514.
- Added a Cache Guard CI integration test suite simulating prefix-cache behaviour across nine scenarios, gated behind CODEWHALE_CACHE_GUARD=1, harvested from #2503.
- Added a plan-mode byte-stability invariant test verifying that the tool catalog head remains byte-identical across mode toggles, harvested from #2519.
- Localized all 15 /queue command messages across 7 shipped locales, harvested from #2568.
- Added localized FanoutCounts MessageId for i18n of the aggregate worker stats line in fanout cards, harvested from #2566.
- Added contribution gate CI workflows (PR gate, issue gate, contributor approval) with a dry-run mode, harvested from #2565.
Changed
- Hardened theme repainting and sidebar color use so theme switches do not leave stale Whale-dark panel colors behind.
- Made legacy config migration visible when CodeWhale copies old DeepSeek-era config into the CodeWhale config path.
Fixed
- Fixed /context to use the effective routed model for context-window budgeting, so DeepSeek V4 routes report the 1M-token window and legacy DeepSeek routes keep the 128K fallback.
- Fixed npm wrapper version output so --version prefers the installed binary version instead of stale package metadata when both are available.
- Fixed multiline composer arrow navigation so holding Up/Down at the first or last line no longer replaces the current draft with prompt history.
- Fixed foreground exec_shell output collection so timeout and inherited-pipe cleanup cannot wedge later tool calls behind the global tool lock.
- Clarified the English DeepSeek account-balance footer chip from bal to balance so it is less likely to be mistaken for session spend.
- Fixed truncated subagent tool calls and repeated truncated subagent responses so they return model-visible errors instead of silently failing.
- Moved Paste to the first position in the right-click context menu so users copying text from the output area can paste with a single left-click instead of navigating past cell-specific actions.
