feat: Add Links Notation configuration support with lino-arguments

[konard]

Summary

Implements full Links Notation configuration support for the trading bot, following the structure and patterns from lino-arguments for Rust. This provides a unified configuration system that merges settings from multiple sources with a clear priority chain.

Project Structure

lib/rust/lino_args/ Module:

• Relocated to ./lib/rust/ directory to prepare for multi-language implementations (following lino-arguments monorepo pattern)
• Comprehensive README.md with full API documentation, usage examples, and integration guides
• Case conversion utilities: to_upper_case, to_camel_case, to_kebab_case, to_snake_case, to_pascal_case
• Environment variable helpers with case-insensitive lookup: getenv, getenv_int, getenv_bool, getenv_decimal, getenv_u64
• Lenv file loading support for .lenv configuration files
• Auto-loading of lenv files from CLI args, environment, or common locations

CLI Support:

• Full CLI argument parsing with clap
• Options: --config, --lenv, --log-level, --verbose, --dry-run, --account, --user, --balance-interval, --order-delay, --run-once, --demo
• All options have corresponding environment variable support (e.g., TRADER_BOT_CONFIG, TRADER_BOT_LOG_LEVEL)

Configuration Priority Chain (Links Notation):

1. CLI arguments (highest priority)
2. Environment variables (case-insensitive)
3. Configuration files (lenv or JSON)
4. Default values

Documentation

The lib/rust/lino_args/README.md provides:

• Complete API reference for all functions
• Usage examples with code snippets
• Integration guides for Clap
• Lenv file format specification
• Case conversion utilities documentation

Usage Examples

# Run with config file
trader-bot --config config.json

# Run with environment variables
TRADER_BOT_LOG_LEVEL=debug TRADER_BOT_DRY_RUN=true trader-bot

# Run with lenv file
trader-bot --lenv .lenv

# Run demo mode
trader-bot --demo

# All options via env vars (case-insensitive)
TRADER_BOT_BALANCE_INTERVAL=3600 trader-bot
traderBotBalanceInterval=3600 trader-bot  # camelCase also works

Test Plan

• All 113 unit tests pass
• All 9 integration tests pass
• All 12 doc tests pass
• cargo fmt --check passes
• cargo clippy --all-targets --all-features passes with no warnings
• Demo mode verified working: cargo run -- --demo
• Help command verified: cargo run -- --help

Changes Summary

1. Documentation: Added comprehensive README.md for lino_args module
2. Structure: Moved lino_args to ./lib/rust/ directory for better organization
3. Compatibility: All imports updated, no breaking changes to public API
4. Testing: All tests continue to pass with the new structure

How about docs? Move lino args to root folder ./lib (outside js and rust versions).

Ensure all changes are correct, consistent and fully meet the requirements.
