feat(auth): add multi-provider authentication with secure credential storage

Authentication System:
- Add credentials crate with keyring (OS keychain) and file fallback storage
- Add auth-manager crate for unified auth across providers
- Implement API key login flow for Anthropic, OpenAI, and Ollama Cloud
- Add CLI commands: login, logout, auth (status)
- Store credentials securely in macOS Keychain / GNOME Keyring / Windows Credential Manager

API Key Helpers:
- Support for password manager integration (1Password, Bitwarden, pass, AWS Secrets, Vault)
- Command-based helpers with TTL caching
- Priority chain: env vars → helpers → cache → stored credentials

Background Token Refresh:
- Automatic OAuth token refresh before expiration
- Configurable check interval and refresh threshold

MCP OAuth Support:
- Add OAuth config to MCP server definitions
- Support for SSE/HTTP transport with OAuth
- Token storage with mcp: prefix

Bug Fixes:
- Fix keyring crate requiring explicit backend features (was using mock store)
- Fix provider index not updated on credential store
- Add User-Agent headers to avoid Cloudflare blocks

//! Background Token Refresh
//!
//! Provides automatic background token refresh for OAuth credentials before they expire.
//! This prevents authentication failures during long-running sessions.
//!
//! # Architecture
//!
//! The `TokenRefresher` spawns a background tokio task that:
//! 1. Runs every `check_interval` (default: 5 minutes)
//! 2. Scans all stored OAuth tokens
//! 3. Refreshes any tokens expiring within `refresh_threshold` (default: 10 minutes)
//! 4. Updates both credential store and in-memory cache on success
//!
//! # Usage
//!
//! ```rust,ignore
//! use auth_manager::{AuthManager, TokenRefresher, RefreshConfig};
//!
//! let auth_manager = AuthManager::new()?;
//! let refresher = TokenRefresher::start(auth_manager.clone(), RefreshConfig::default());
//!
//! // The refresher runs in the background
//! // Stop it when shutting down
//! refresher.stop();
//! ```

//! API Key Helpers
//!
//! Provides dynamic API key retrieval from external password managers and secret stores.
//! This allows users to store their credentials securely while still using them with Owlen.
//!
//! # Supported Password Managers
//!
//! - **1Password CLI:** `op read "op://vault/item/field"`
//! - **Bitwarden CLI:** `bw get password item`
//! - **pass (Unix):** `pass show path/to/secret`
//! - **Custom commands:** Any shell command that outputs the secret
//!
//! # Configuration
//!
//! API key helpers are configured in your config file:
//!
//! ```toml
//! [credentials.helpers]
//! anthropic = { command = "op read 'op://Private/Anthropic/api_key'" }
//! openai = { command = "pass show openai/api_key", ttl_secs = 3600 }
//! ```
//!
//! # Caching
//!
//! Command results are cached for a configurable TTL (time-to-live) to avoid
//! repeatedly executing potentially slow commands (like 1Password which may
//! require unlocking). Default TTL is 5 minutes.
//!
//! # Usage
//!
//! ```rust,ignore
//! use credentials::helpers::{ApiKeyHelper, CommandHelper};
//!
//! // Create a helper for 1Password
//! let helper = CommandHelper::new("op read 'op://Private/Anthropic/api_key'")
//! .with_ttl(Duration::from_secs(600));
//!
//! // Get the key (executes command if cache expired)
//! let api_key = helper.get_key()?;
//! ```
