* feat(core): add RPC rate limiting, retry logic, and 429 handling Addresses #44 — users on free-tier RPC endpoints hit HTTP 429 errors during buy transactions due to no rate limiting or retry handling. - Add TokenBucketRateLimiter (new file: src/core/rpc_rate_limiter.py) - Gate all RPC methods through rate limiter (both post_rpc and solana-py calls) - Rewrite post_rpc() with retry loop, exponential backoff, jitter, and specific 429 detection with Retry-After header support - Replace per-call aiohttp session with shared persistent session - Wire node.max_rps from YAML bot config through to SolanaClient - Fix cleanup manager and learning example to use SolanaClient abstraction instead of bypassing it via get_client() Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com> * fix(core): address CodeRabbitAI review feedback on rate limiting PR Validate max_rps > 0 in TokenBucketRateLimiter to prevent ZeroDivisionError and infinite loops with fractional values. Add asyncio.Lock to _get_session to fix race condition, handle non-numeric Retry-After headers gracefully, replace dead json.JSONDecodeError with aiohttp.ContentTypeError, and combine burn+close into a single transaction in cleanup example. Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com> * docs: document RPC rate limiting feature in README - Add section on built-in RPC rate limiting with token bucket algorithm - Document configurable max RPS and automatic retry logic - Update roadmap to mark "Configurable RPS" as completed - Clarify benefits of rate limiting for provider compliance Co-Authored-By: Claude Sonnet 4.5 <noreply@anthropic.com> * fix: use math.ceil for burst_size to handle fractional max_rps - Replace int(max_rps) with math.ceil(max_rps) in burst_size calculation - Prevents infinite loop when max_rps < 1.0 (e.g., 0.5 RPS would result in burst_size=0) - Ensures burst_size is always at least 1 for valid fractional rates - Addresses CodeRabbit feedback on rpc_rate_limiter.py:27 Co-Authored-By: Claude Sonnet 4.5 <noreply@anthropic.com> * fix(core): validate burst_size and fix table pipe consistency Address remaining CodeRabbitAI review feedback: add burst_size validation guard, fix TRY003 lint (use msg variable for ValueError), break long line under 88 chars, and fix MD055 table pipe style in README. Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com> * fix(core): separate 429 retry budget from error retries in post_rpc 429 responses no longer count against max_retries — they use a dedicated max_429_retries counter (default 10) so free-tier users hitting rate limits won't exhaust retries prematurely. Also refresh the aiohttp session inside the retry loop to avoid stale references after network failures, and fix cleanup log message accuracy.
