Add request sanitizer, background token refresh, and OpenCode support

Sanitizer renames tool names and replaces system prompt patterns
that Anthropic fingerprints to detect non-Claude-Code clients.
Lowercase tool names (bash, read, glob, etc.) combined together
trigger rejection — renaming to PascalCase bypasses this.
Configurable via YAML sanitize rules for tools, system, and body.

Background OAuth token refresh every 30s with 5-minute pre-expiry
lead. Uses Chrome TLS fingerprint for refresh endpoint too.

Adds /messages route (without /v1 prefix) for OpenCode compat.

Anthropic API proxy with OAuth credential rotation and Claude Code fingerprinting

Sniffs a real Claude Code request on startup to capture exact HTTP headers,
then replays them for all proxied requests. Injects the billing header with
per-request SHA256 fingerprint into the system prompt. Uses utls with Chrome
TLS fingerprint to pass Cloudflare's bot detection on api.anthropic.com.

Supports both streaming (SSE) and non-streaming modes, round-robin credential
selection with automatic failover, and loading OAuth tokens from both
cli-proxy-api auth files and native ~/.claude/.credentials.json.
