feat(setup): interactive setup wizard + install.sh (#23644)

* feat(setup): add interactive setup wizard + install.sh

Adds `litellm --setup` — a Claude Code-style TUI onboarding wizard that
guides users through provider selection, API key entry, and proxy config
generation, then optionally starts the proxy immediately.

- litellm/setup_wizard.py: wizard with ASCII art, numbered provider menu
  (OpenAI, Anthropic, Azure, Gemini, Bedrock, Ollama), API key prompts,
  port/master-key config, and litellm_config.yaml generation
- litellm/proxy/proxy_cli.py: adds --setup flag that invokes the wizard
- scripts/install.sh: curl-installable script (detect OS/Python, pip
  install litellm[proxy], launch wizard)

Usage:
  curl -fsSL https://raw.githubusercontent.com/BerriAI/litellm/main/scripts/install.sh | sh
  litellm --setup

* fix(install.sh): remove orange color, add LITELLM_BRANCH env var for branch installs

* fix(install.sh): install from git branch so --setup is available for QA

* fix(install.sh): remove stale LITELLM_BRANCH reference that caused unbound variable error

* fix(install.sh): force-reinstall from git to bypass cached PyPI version

* fix(install.sh): show pip progress bar during install

* fix(install.sh): always launch wizard via $PYTHON_BIN -m litellm, not PATH binary

* fix(install.sh): use litellm.proxy.proxy_cli module (no __main__.py exists)

* fix(install.sh): suppress RuntimeWarning from module invocation

* fix(install.sh): use Python bin-dir litellm binary to avoid CWD sys.path shadowing

* fix(install.sh): use sysconfig.get_path('scripts') to find pip-installed litellm binary

* fix(install.sh): redirect stdin from /dev/tty on exec so wizard gets terminal, not exhausted pipe

* fix(install.sh): warn about git clone duration, drop --no-cache-dir so re-runs are faster

* feat(setup_wizard): arrow-key selector, updated model names

* fix(setup_wizard): use sysconfig binary to start proxy, not python -m litellm

* feat(setup_wizard): credential validation after key entry + clear next-steps after proxy start

* style(install.sh): show git clone warning in blue

* refactor(setup_wizard): class with static methods, use check_valid_key from litellm.utils

* address greptile review: fix yaml escaping, port validation, display name collisions, tests

- setup_wizard.py: add _yaml_escape() for safe YAML embedding of API keys
- setup_wizard.py: add _styled_input() with readline ANSI ignore markers
- setup_wizard.py: change DIVIDER to _divider() fn to avoid import-time color capture
- setup_wizard.py: validate port range 1-65535, initialize before loop
- setup_wizard.py: qualify azure display names (azure-gpt-4o) to avoid collision with openai
- setup_wizard.py: work on env_copy in _build_config to avoid mutating caller's dict
- setup_wizard.py: skip model_list entries for providers with no credentials
- setup_wizard.py: prompt for azure deployment name
- setup_wizard.py: wrap os.execlp in try/except with friendly fallback
- setup_wizard.py: wrap config write in try/except OSError
- setup_wizard.py: fix _validate_and_report to use two print lines (no \r overwrite)
- setup_wizard.py: add .gitignore tip next to key storage notice
- setup_wizard.py: fix run_setup_wizard() return type annotation to None
- scripts/install.sh: drop pipefail (not supported by dash on Ubuntu when invoked as sh)
- scripts/install.sh: use litellm[proxy] from PyPI (not hardcoded dev branch)
- scripts/install.sh: guard /dev/tty read with -r check for Docker/CI compat
- scripts/install.sh: remove --force-reinstall to avoid downgrading dependencies
- tests/test_litellm/test_setup_wizard.py: 13 unit tests for _build_config and _yaml_escape

* style: black format setup_wizard.py

* fix: address remaining greptile issues - Windows compat, YAML quoting, credential flow

- guard termios/tty imports with try/except ImportError for Windows compat
- quote master_key as YAML double-quoted scalar (same as env vars)
- remove unused port param from _build_config signature
- _validate_and_report now returns the final key so re-entered creds are stored
- add test for master_key YAML quoting

* fix: add --port to suggested command, guard /dev/tty exec in install.sh

* fix: quote api_base in YAML, skip azure if no deployment, only redraw on state change

* fix: address greptile review comments

- _yaml_escape: add control character escaping (\n, \r, \t)
- test: fix tautological assertion in test_build_config_azure_no_deployment_skipped
- test: add tests for control character escaping in _yaml_escape

@ -140,6 +140,11 @@ LiteLLM is a unified interface for 100+ LLM providers with two main components:
- **Check index coverage.** For new or modified queries, check `schema.prisma` for a supporting index. Prefer extending an existing index (e.g. `@@index([a])` → `@@index([a, b])`) over adding a new one, unless it's a `@@unique`. Only add indexes for large/frequent queries.
- **Keep schema files in sync.** Apply schema changes to all `schema.prisma` copies (`schema.prisma`, `litellm/proxy/`, `litellm-proxy-extras/`, `litellm-js/spend-logs/` for SpendLogs) with a migration under `litellm-proxy-extras/litellm_proxy_extras/migrations/`.
### Setup Wizard (`litellm/setup_wizard.py`)
- The wizard is implemented as a single `SetupWizard` class with `@staticmethod` methods — keep it that way. No module-level functions except `run_setup_wizard()` (the public entrypoint) and pure helpers (color, ANSI).
- Use `litellm.utils.check_valid_key(model, api_key)` for credential validation — never roll a custom completion call.
- Do not hardcode provider env-key names or model lists that already exist in the codebase. Add a `test_model` field to each provider entry to drive `check_valid_key`; set it to `None` for providers that can't be validated with a single API key (Azure, Bedrock, Ollama).
### Enterprise Features
- Enterprise-specific code in `enterprise/` directory
- Optional features enabled via environment variables
