v0.2.1

Added

• faker --describe (no args) shows full tool self-description for agents
• --format csv output with RFC 4180 compliance (header rows, proper escaping)

Fixed

• --schema with leading whitespace no longer treated as a file path
• Schema errors now show which method failed and suggest --describe
• Extra positional args now warn instead of being silently ignored
• --count capped at 100,000 to prevent unbounded memory/time
• CSV: nested objects serialized as JSON in cells instead of [object Object]
• CSV: header keys with commas/quotes properly escaped
