/**
 * Resolve the ECC source root directory.

 * Tries, in order:
 *   1. CLAUDE_PLUGIN_ROOT env var (set by Claude Code for hooks, or by user)
 *   2. Standard install location (~/.claude/) — when scripts exist there
 *   3. Known plugin roots under ~/.claude/plugins/ (current + legacy slugs)
 *   4. Plugin cache auto-detection — scans ~/.claude/plugins/cache/{ecc,everything-claude-code}/
 *   5. Fallback to ~/.claude/ (original behaviour)
 *
 * @param {object} [options]
 * @param {string} [options.homeDir]  Override home directory (for testing)
 * @param {string} [options.envRoot]  Override CLAUDE_PLUGIN_ROOT (for testing)
 * @param {string} [options.probe]    Relative path used to verify a candidate root
 *                                    contains ECC scripts. Default: 'scripts/lib/utils.js'
 * @returns {string} Resolved ECC root path

/**
 * Compact inline locator for embedding in hooks.json and command .md code blocks.
 *
 * Earlier revisions inlined the *entire* resolveEccRoot() search (~700 chars,
 * duplicated ~80×). That blob used a spread (`...s`) over nested array literals,
 * which broke Windows hook execution due to shell quoting (#2368).
 *
 * This minified form instead does the minimum needed to locate and load the
 * committed resolve-ecc-root module, then delegates the real search to
 * resolveEccRoot(). It contains no spread, no nested array literals, and no
 * escaped double quotes, so it survives `node -e "..."` quoting on every shell.
 *
 * It loads the module from CLAUDE_PLUGIN_ROOT (set by Claude Code for plugin
 * hooks and commands) or, when unset, from ~/.claude (the direct-install
 * location). resolveEccRoot() then resolves the true root — including the
 * marketplace/plugin-cache locations — from there.
 *
 * Usage in commands:
 *   const _r = <paste INLINE_RESOLVE>;
 *   const sm = require(_r + '/scripts/lib/session-manager');
