v0.4.0-alpha — dev-environment commands

First release on the 0.4 line. Adds the dev-environment command surface — every CWM extension can now drive its local Joomla dev workflow through composer-script aliases instead of carrying its own ~1400-line build script.

Added

• cwm-setup — interactive wizard; writes build.properties (paths, URLs, versions, DB creds, admin creds).
• cwm-link — symlinks the project tree into every configured Joomla install. Auto-derives the standard set from extension.* and manifests.extensions[] (component admin/site/media; library lib_X → libraries/X + manifest mirror; plugins/<group>/<element>; modules/[admin]/<name>). Explicit dev.links[] and dev.internalLinks[] merged in. All symlinks created with relative paths so the dev tree is portable across machines and CI.
• cwm-link-check — verifies every expected symlink without recreating; non-zero exit on drift, CI-friendly.
• cwm-clean — removes every dev symlink; real files at the link paths are left alone.
• cwm-verify — confirms each install has every project sub-extension registered in #__extensions. Reads each manifest XML to discover type/element/folder/namespace; uses PDO so it does not bootstrap Joomla. --fix reconciles drift (UPDATE state, INSERT missing libraries/plugins, run library install SQL).
• cwm-joomla-install — downloads the Joomla full-package release into every configured install path. --force to overwrite.
• cwm-joomla-latest — prints the latest stable tag from the joomla-cms releases feed.
• src/Dev/: InstallConfig, PropertiesReader, LinkResolver, Linker, ExtensionVerifier, JoomlaInstaller (PSR-4, PHP 8.3+).
• templates/build.properties.tmpl and a new dev: block in cwm-build.config.json.tmpl.
• templates/gitignore-managed.txt includes build.properties so consumers pick it up via composer sync-configs.

Configuration split

File	Committed?	Purpose
cwm-build.config.json	yes	What the project IS — extension layout, manifest paths, optional dev: block. No secrets.
build.properties	no — gitignored	Where the developer's local installs live: paths, URLs, versions, DB and admin credentials.

PropertiesReader accepts both the new INI-section format and Proclaim's legacy flat builder.joomla_paths= layout, so consumers migrating from Proclaim can drop the new toolchain in without rewriting their existing properties first.

Changed (breaking)

• Removed ars.changelogUrl from the config schema (modern Akeeba ARS has no changelogurl field on #__ars_updatestreams). Migration: move the value to changelog.url and add a <changelogurl> element to your top-level extension manifest. See full notes in CHANGELOG.md.
