701 Pr C739ee97

## Summary
- **Added HubSpot integration** — new HubSpot MCP tool with search, get, create, and update operations for contacts, companies, and deals. Includes OAuth2 provider for HubSpot credentials and credential store adapter for the tools layer.
- **Replaced web_scrape tool with Playwright + stealth** — swapped httpx/BeautifulSoup for a headless Chromium browser using `playwright` (async API) and `playwright-stealth`, enabling JS-rendered page scraping and bot detection evasion
- **Added empty response retry logic** — LLM provider now detects empty responses (e.g. Gemini returning 200 with no content on rate limit) and retries with exponential backoff, preventing hallucinated output from the cleanup LLM
- **Added context-aware input compaction** — LLM nodes now estimate input token count before calling the model and progressively truncate the largest values if they exceed the context window budget
- **Increased rate limit retries to 10** with verbose `[retry]` and `[compaction]` logging that includes model name, finish reason, and attempt count
- **Updated setup scripts** — `scripts/setup-python.sh` now installs Playwright Chromium browser automatically for web scraping support
- **Interactive quickstart onboarding** — `quickstart.sh` rewritten as bee-themed interactive wizard that detects existing API keys (including Claude Code subscription), lets user pick ONE default LLM provider, and saves configuration to `~/.hive/configuration.json`
- **Fixed lint errors** across `hubspot_tool.py` (line length) and `agent_builder_server.py` (unused variable)

## Test plan
- [ ] Run `make lint` — passes clean
- [ ] Run `./quickstart.sh` and verify interactive flow works, config saved to `~/.hive/configuration.json`
- [ ] Run `./scripts/setup-python.sh` and verify Playwright Chromium installs
- [ ] Run `pytest tests/tools/test_web_scrape_tool.py -v`
- [ ] Run agent against a JS-heavy site and verify `web_scrape` returns rendered content
- [ ] Set `HUBSPOT_ACCESS_TOKEN` and verify HubSpot tool CRUD operations work
- [ ] Trigger rate limit and verify `[retry]` logs appear with correct attempt counts
- [ ] Run agent with large inputs and verify `[compaction]` logs show truncation
