From 195811e81b8daaaf8e6ab1dcc6c686afeda36c8b Mon Sep 17 00:00:00 2001 From: Maxwell Date: Mon, 29 Jun 2026 14:18:33 +0200 Subject: [PATCH 01/11] chore(project): bootstrap Deno workspace and CI - Deno 2.x project structure with deno.json and task definitions - JSR dependencies: @cliffy/command, @std/assert, @std/testing, @std/yaml, @std/dotenv, @std/fs, @std/path - Full CLI command tree with stubs for all 15 issues - Shared interfaces (ProcessRunner, config types, ExitCode) for parallel work - FakeProcessRunner with recording, pre-programmed responses, and dry-run support - CI pipeline: fmt, lint, typecheck, test, coverage, and cross-platform build - .gitignore for generated and environment-specific files --- .github/workflows/ci.yml | 71 +++++++++++ .gitignore | 29 +++++ deno.json | 52
