v0.90.0 — Stabilization & Release Hardening

Highlights

• Package rename complete: jarvis → cognithor (both CLI commands preserved)
• Release pipeline hardened: Pre-release smoke test validates built wheel on 2 OS before PyPI upload
• All 5 GitHub issues fixed: #104, #105, #106, #107, #108

Bug Fixes

• #104 first_run.py KeyError — config structure fixed from nested to flat
• #105 Model switching — model_post_init no longer overrides explicit llm_backend_type when API keys exist in keyring
• #106 Upgrade corruption — auto-migrate ~/.jarvis/ → ~/.cognithor/, keyring fallback, corrupt DB recovery
• #107 Frontend disconnect — ConnectionGuard overlay blocks UI when backend unreachable, 15s health polling
• #108 Invisible backend — pythonw.exe in --ui mode, Live Logs tab in MonitoringScreen

Infrastructure

• Environment variable overrides: JARVIS_* prefix supported for backward compatibility
• Version consistency check in CI (pyproject.toml vs init.py)
• scripts/prepare_release.py for local pre-release validation
• scripts/verify_readme_claims.py for README claims audit
• README: Pre-v1.0 Beta disclaimer, corrected numeric claims

New Tests

29 new tests: release smoke (4), env overrides (18), security regression (2), migration (5)
