Remove legacy env-var-based provider/mode detection that caused misleading
UI badges (e.g., GLM badge showing when Settings was set to Claude).
Key changes:
- Remove _is_glm_mode() and _is_ollama_mode() env-var sniffing functions
from server/routers/settings.py; derive glm_mode/ollama_mode purely from
the api_provider setting
- Remove `import os` from settings router (no longer needed)
- Update schema comments to reflect settings-based derivation
- Remove "(configured via .env)" from badge tooltips in App.tsx
- Remove Kimi/GLM/Ollama/Playwright-headless sections from .env.example;
add note pointing to Settings UI
- Update CLAUDE.md and README.md documentation to reference Settings UI
for alternative provider configuration
- Update model IDs from claude-opus-4-5-20251101 to claude-opus-4-6
across registry, client, chat sessions, tests, and UI defaults
- Add LEGACY_MODEL_MAP with auto-migration in get_all_settings()
- Show model ID subtitle in SettingsModal model selector
- Add Vertex passthrough test for claude-opus-4-6 (no date suffix)

- Rename compute_mode -> convert_model_for_vertex for clarity
- Move `import re` to module top-level (stdlib convention)
- Use greedy regex quantifier for more readable pattern matching
- Restore PEP 8 double blank line between top-level definitions
- Add test_client.py with 10 unit tests covering:
- Vertex disabled (env unset, "0", empty)
- Standard conversions (Opus, Sonnet, Haiku)
- Edge cases (already-converted, non-Claude, no date suffix, empty)
Follow-up improvements from PR #129 review.
