v1.9.0 — AGENTS.md + Comprehensive Test Suite

v1.9.0 — AGENTS.md + Comprehensive Tests

New

• AGENTS.md support: Drop \AGENTS.md\ or .coding-agent.md\ in your project root. Auto-loaded and injected into system prompt for both CLI and Web.
• \loadProjectContext.ts\ — new module, walks up to 3 parent directories looking for context files
• Sample \AGENTS.md\ included for the project itself

Tests: 41 → 84 unit tests (+ 35 integration = 119 total)

• \CodingAgent.test.ts\ (11 tests): execute loop, stream parsing, stuck detection, retry/timeout, HTTP 429/500 error handling
• \loadProjectContext.test.ts\ (7 tests): file lookup, directory walk, empty file, both naming conventions
• \ileManager.test.ts\ (26 tests): all 13 tools (write, read, list, copy, move, delete, search, replace, run, append, folder ops, file_info) + safe mode + unknown tool

Fixes

• \withRetryAndTimeout\ preserves original error properties (fixes 429 status detection during auto-fallback)
• \deleteFolder\ handles Windows \ERR_FS_EISDIR\ (was only checking \ENOTEMPTY)

Changed

• v1.8.0 → v1.9.0
