fix: RAG chunking crash using non-existent converter.output_dir

DocToSkillConverter has self.skill_dir (string), not self.output_dir.
The --chunk-for-rag flag on scrape command crashed with AttributeError.
Changed to Path(converter.skill_dir).

 ### Fixed
+- **RAG chunking crash (`AttributeError: output_dir`)** — `execute_scraping_and_building()` used `converter.output_dir` which doesn't exist on `DocToSkillConverter`. Changed to `Path(converter.skill_dir)`. Affected `--chunk-for-rag` flag on `scrape` command.
 - **Issue #301: `setup.sh` fails on macOS with mismatched Python/pip** — `pip3` can point to a different Python than `python3` (e.g. pip3 → 3.9, python3 → 3.14), causing "no matching distribution" errors. Changed `setup.sh` to use `python3 -m pip` instead of bare `pip3` to guarantee the correct interpreter.
 - **Issue #300: Selector fallback & dry-run link discovery** — `create https://reactflow.dev/` now finds 20+ pages (was 1). Root causes:
   - `extract_content()` extracted links after the early-return when no content selector matched, so they were never discovered. Moved link extraction before the early return.
