- Add branding/ directory with configuration-driven white-labeling
- Support custom logos, binary names, env var prefixes, and models
- Include qBraid/CodeQ configuration with purple Q in TUI
- Replace Zen models with qBraid, Anthropic, OpenAI providers
- Add documentation and safe testing workflow via git worktrees

- Update all system prompts to say 'CodeQ, built by qBraid - the leading quantum software company. You are the universe's most powerful coding agent.'
- Add .txt files to processed extensions so prompts are branded
- Replace all OpenCode references with CodeQ in prompts

…ve mode

- Clear BUILTIN plugin array when models.exclusive=true
- Empty CUSTOM_LOADERS when in exclusive mode to prevent 'Provider does not exist' errors
- Fix applyFileTransform to apply ALL matching transforms per file
- Update qBraid models.json to only include qBraid provider with 4 models:
  claude-sonnet-4-5, claude-haiku-4-5, gemini-3-flash, grok-4.1-fast

- Create branding/qbraid/README.md with CodeQ user documentation
- Fix inaccurate models description in branding/README.md

Builds CodeQ binaries for all platforms (linux, darwin, windows / x64, arm64)
and uploads them to gs://qbraid-codeq bucket.

Features:
- Manual dispatch with optional version input
- Builds all platform variants in parallel
- Applies qBraid branding before build
- Uploads versioned binaries to GCS
- Creates manifest.json with download URLs
- Updates 'latest' folder for release versions (v*)

feat: add qBraid branding system for white-labeling as CodeQ

Allows specifying which branch/tag/SHA to build from.
This is needed to test the workflow before the branding
code is merged to dev.

The branding scripts import zod but weren't part of the workspace,
causing 'Cannot find package zod' errors in CI.

- Add branding/package.json with zod catalog dependency
- Add branding to root workspaces list

fix(branding): workspace and CI fixes for CodeQ GCS workflow

Implements proper handling of Gemini 3 thought signatures in multi-turn
function calling conversations. Gemini 3 requires thought signatures to be
passed back when sending tool results.

Changes:
- Add new qBraid provider SDK at src/provider/sdk/qbraid/ that:
  - Uses a custom metadata extractor to capture _thought_signature from
    tool calls in both streaming and non-streaming responses
  - Stores thought signatures globally keyed by toolCallId
  - Exports getThoughtSignature() for retrieval

- Update processor.ts to:
  - Import getThoughtSignature from qBraid provider
  - Look up thought signatures after receiving tool-call events
  - Attach them to part metadata under both 'vertex' and 'google' keys
    for AI SDK compatibility

- Register qBraid provider in provider.ts BUNDLED_PROVIDERS

- Update branding/qbraid/models.json to use @ai-sdk/qbraid npm identifier
  so CodeQ uses our custom provider instead of generic openai-compatible

This works in conjunction with the qbraid-account proxy changes that:
1. Extract thought signatures from Gemini responses
2. Include them as _thought_signature in OpenAI-compatible tool call responses
3. Read _thought_signature from incoming requests and pass to AI SDK

feat: add Gemini 3 thought signature support for qBraid provider
