fix: correct which claude resolution in find_all_cli_js()

- Handle case where which claude resolves directly to cli.js (not to .bin/claude)
- When claude binary basename is cli.js, add it directly to candidates
- When claude binary is in .bin/, resolve to parent node_modules/@anthropic-ai/claude-code/cli.js
- Fixes: which claude path not being properly included in multi-install patching
