This reverts commit e7c29fb410.
The PR introduced an IndexedDB error: 'Failed to execute transaction on IDBDatabase: The database connection is closing.'
* fix(electron): prevent beforeunload prompt by using autosave
- Enable draw.io autosave and handle autosave events to update chartXML
- Clear modified state after autosave to avoid beforeunload prompts
- Disable confirmExit in draw.io configuration
- Set modified=false and keepmodified=false URL parameters
- Fix session save condition to also save when only diagram exists
* fix: persist diagram-only saves and ref typing
* fix: harden persistence checks and export timeout
* feat(electron): bundle draw.io for offline support
- Download draw.io static files during CI build (v29.3.5)
- Detect Electron and use local draw.io files instead of CDN
- Add offline=1 parameter to disable external service calls
- Skip /drawio path from i18n middleware redirect
- Add public/drawio/ to .gitignore (downloaded during build)
This allows the Electron app to work completely offline.
* chore: bump version to 0.4.12-beta.3 for offline test
* fix(electron): ad-hoc sign macOS app for bundled draw.io compatibility
* chore: bump version to 0.4.12-beta.4 for ad-hoc sign test

- Update button styles to match header design
- Change title to "Next AI Draw.io"
- Rename "Save" to "Download" for clarity
- Bump version to 0.1.15
* chore: remove dead code (unused download helpers and pendingManualSave)
Fixes#633 - browser showing infinite loading spinner when accessing
the MCP server URL without the session parameter.
When users access http://localhost:6002 directly (without ?mcp=xxx),
the page now auto-redirects to the most recent active session instead
of showing "No session" with an infinite loading spinner.
Upgrade wrangler from 4.58.0 to ^4.60.0 to fix the command injection
vulnerability (CWE-78) in the --commit-hash parameter of wrangler pages
deploy command.
Fixes#627
* fix(quota): bypass quota for users with Bedrock credentials
The hasOwnApiKey check only looked for x-ai-api-key header, but Bedrock
users provide AWS credentials via x-aws-access-key-id instead. This
caused Bedrock users with their own credentials to still be subject to
quota limits.
* fix(quota): also bypass quota for Vertex AI users
* style: auto-format with Biome

cpSync with dereference:true does NOT convert symlinks to files.
This implements a custom copyDereferenced function that:
- Detects symlinks using lstatSync
- Follows them using statSync
- Copies actual file/directory content instead of symlink
Fixes macOS arm64 codesign failure with electron-builder 26.4.0
which now does ad-hoc signing and runs codesign --verify.
* fix: allow private URLs by default for reverse proxy setups
Fixes#588 - Users with reverse proxy setups (e.g., Antigravity tools)
were getting "Invalid base URL" errors due to SSRF protection blocking
private/internal URLs.
Changes:
- Add ALLOW_PRIVATE_URLS env var (defaults to true)
- Set to "false" to enable strict SSRF protection if needed
* refactor: extract isPrivateUrl to shared utility
After create_new_diagram, edit_diagram would fail with "You must call
get_diagram first" because lastGetDiagramTime was never set (remained 0
from session init). This fix sets lastGetDiagramTime after creating a
diagram, allowing immediate edits.
Fixes#534, Fixes#589

SiliconFlow is transitioning from .com to .cn domain. The .cn endpoint
uses Global Traffic Manager (GTM) for better global access, while .com
is being phased out.

- Add dist:win:build script with --publish never
- Integrate SignPath signing for Windows executables
- Sign both NSIS installer and portable EXE files
DeepSeek provider was not properly formatting image content for Doubao's
API. Now uses OpenAI provider for Doubao models (multimodal support),
while keeping DeepSeek provider for DeepSeek/Kimi models on the platform.
Dockerfile was missing the ARG declaration to receive NEXT_PUBLIC_BASE_PATH
from docker-compose build args, causing subdirectory deployment to fail.

PR #442 accidentally changed showSaveDialog from using the diagram
context to local state, breaking draw.io's native save button (Ctrl+S)
that was fixed in PR #296.
This restores the original behavior by using the context's showSaveDialog
so both draw.io native save and the download button open the same dialog.

* chore(mcp-server): bump version to 0.1.11
Some models (Kimi K2, DeepSeek, Qwen text models) don't support image/vision
input. The AI SDK silently drops unsupported image parts, causing confusing
responses where the model acts as if no image was uploaded.
Added supportsImageInput() function to detect unsupported models by name,
and return a 400 error with clear guidance when users try to upload images
to these models.

- Use fixed port 61337 in production instead of random ports (10000-65535)
- localStorage is origin-specific, so random ports caused settings loss
- Add locale save/restore since language is URL-based
