feat: relicense AGPL-3.0 → MIT (v2.7.0)
Clear the 3 Unsloth-Studio-derived AGPL files and flip LICENSE + 5 package.json from AGPL-3.0-only to MIT. - html-to-md.ts → MIT node-html-markdown (parse5 dropped) - llama-args-validator.ts → clean-room (flag denylist = facts) - tool-call-parser.ts → delete dead Unsloth-ported code; keep extractToolCallBlocks/stripToolMarkup byte-identical (no behavior change) - LICENSE → MIT (Copyright (c) 2026 indifferentketchup); 5 package.json → MIT; AGPL SPDX headers removed; README License section; license-mit guard test - roadmap License-debt batch marked shipped; openspec/changes/license-debt-mit Decouples the relicense from the native-parsing retirement (the ported parser was dead code). Server suite 519 passing; build + coder typecheck clean. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
