/**
 * Project discovery walker — scans user-specified roots for Claude Code
 * projects. Intentionally light-weight: stops recursing into a directory as
 * soon as a Claude Code signature is detected, so `$HOME`-wide scans stay
 * fast even with many nested projects.
 *
 * Safety:
 *   - Symbolic links are not followed (cycle prevention); visited inodes
 *     are also tracked via realpath as a secondary guard.
 *   - Everything inside `node_modules/`, `.git/`, etc. is skipped by name.
 *   - Any readdir / stat failure on a single dir is captured and the scan
 *     continues with the next one.
