When installed via `npm install ecc-universal`, the `ecc-install` bin
entry creates a symlink from the package manager's bin directory to
install.sh. The old `$(dirname "$0")` resolved to the bin directory
instead of the actual package directory, causing `cp` to fail with
"cannot stat '.../rules/common/.'".
Now follows the symlink chain with readlink before resolving SCRIPT_DIR.
Fixes#199
- Validate language names in install.sh to prevent path traversal via
malicious args like ../../etc (only allow [a-zA-Z0-9_-])
- Replace silent catch in check-console-log.js with stderr logging so
hook failures are visible to the user for debugging
- Escape backticks in session-end.js user messages to prevent markdown
structure corruption in session files
Add complete .cursor/ directory with rules, agents, skills, commands,
and MCP config adapted for Cursor's format. This makes ecc-universal
a truly cross-IDE package supporting Claude Code, Cursor, and OpenCode.
- 27 rule files with YAML frontmatter (description, globs, alwaysApply)
- 13 agent files with full model IDs and readonly flags
- 30 skill directories (identical Agent Skills standard, no translation)
- 31 command files (5 multi-* stubbed for missing codeagent-wrapper)
- MCP config with Cursor env interpolation syntax
- README.md and MIGRATION.md documentation
- install.sh --target cursor flag for project-scoped installation
- package.json updated with .cursor/ in files and cursor keywords
