fix: rewrite PHAR tool stubs to only suggest QA pipeline usage

Stubs previously showed misleading "not installed as a standalone binary"
error and suggested running PHARs directly, which defeats the purpose of
consistent configuration managed by php-qa-ci.

Now each stub:
- Resolves the project's bin-dir relative to project root
- Shows only `qa -t <tool>` commands with correct tool names
- Includes `-p` path examples only for tools that support it
- No mention of running PHARs directly
