fix: gitignore log/ dir, remove tracked JSONL from repo

Event logs are runtime data, not source code. Also adds mem compact command and browser-use + memory-service knowledge.

+# browser-use — AI Browser Automation
+
+## What It Is
+- AI agent that controls a real browser via CDP (Chrome DevTools Protocol).
+- Describe task in natural language → agent clicks, types, navigates, extracts data.
+- Python library for code-level automation OR CLI for agent integration (Claude Code, Cursor, etc).
+- Open source, self-hosted. Optional cloud for stealth/scaling.
+
+## Installation
+```bash
+# Python library
+uv add browser-use
+# or: pip install browser-use
+
+# CLI (via uvx, no install needed)
+uvx browser-use
+
+# Install Chromium + dependencies
+browser-use install
+
+# Register skill for coding agents
+browser-use skill install
+```
+
+## CLI Usage
+```bash
+# Run inline Python with pre-imported helpers
+browser-use <<'PY'
+new_tab("https://example.com")
+print(page_info())
+PY
+
+# Check local Chrome connection
+browser-use --doctor
+
+# macOS: approve remote debugging permission
+browser-use mac-approve
+
+# Auth for cloud browsers
+browser-use auth login
+```
+
+## Python Library — Basic Agent
+```python
+import asyncio
+from browser_use import Agent, ChatBrowserUse
+
+async def main():
+    agent = Agent(
+        task="Find the price of iPhone 16 on Amazon",
+        llm=ChatBrowserUse(model='openai/gpt-5.5'),
+    )
+    result = await agent.run()
+    print(result)
+
+asyncio.run(main())
+```
+
+## Structured Output
+```python
+from pydantic import BaseModel, Field
+from browser_use import Agent, ChatBrowserUse
+
+class ProductInfo(BaseModel):
+    title: str = Field(..., description='Product name')
+    price: float = Field(..., description='Price as number')
+    url: str = Field(..., description='Product URL')
+
+agent = Agent(
+    task="Find the top 3 results for 'mechanical keyboard' on Amazon",
+    llm=ChatBrowserUse(model='bu-2-0-mini-preview'),
+    output_model_schema=ProductInfo,
+)
+result = asyncio.run(agent.run())
+if result and result.structured_output:
+    print(result.structured_output)
+```
+
+## Connect to Existing Browser
+```python
+from browser_use import Agent, Browser, ChatBrowserUse
+
+# Connect to local Chrome with CDP
+browser = Browser(cdp_url='http://localhost:9222')
+agent = Agent(browser=browser, llm=ChatBrowserUse(), task="...")
+```
+
+## CLI Helper Functions
+Pre-imported in `browser-use` CLI context:
+- `new_tab(url)` — open URL in new tab (first navigation per task)
+- `goto_url(url)` — navigate current tab
+- `page_info()` — get current page info
+- `current_tab()` — get current tab info
+- `list_tabs()` — list all open tabs
+- `switch_tab(target)` — switch to existing tab
+- `activate_tab(target)` — bring tab to foreground
+- `click_at_xy(x, y)` — click at viewport coordinates
+- `js(code)` — execute JavaScript in page
+- `wait_for_load()` — wait for page load after navigation
+- `ensure_real_tab()` — skip internal/stale tabs
+- `cdp("Domain.method", ...)` — raw CDP command
+- `start_recording(name)` / `stop_recording()` — record session
+
+## Remote/Cloud Browsers
+```bash
+# Start remote browser (for parallel tasks or stealth)
+browser-use <<'PY'
+start_remote_daemon("my-task")
+PY
+
+# Use remote browser
+BU_NAME=my-task browser-use <<'PY'
+new_tab("https://example.com")
+print(page_info())
+PY
+
+# Stop when done (billed until stopped)
+browser-use <<'PY'
+stop_remote_daemon("my-task")
+PY
+```
+
+## Page Interaction Workflow
+1. Find elements via accessibility tree: `cdp("Accessibility.getFullAXTree")["nodes"]`
+2. Get coordinates: `cdp("DOM.getBoxModel", backendNodeId=n)` → compute center
+3. Click: `click_at_xy(x, y)`
+4. Verify: `js(...)` or `page_info()` to confirm action
+5. Fallback to raw HTML via `js(...)` only when AX tree lacks element
+
+## When to Use browser-use vs curl
+- **Use curl**: public pages, APIs, static content, docs
+- **Use browser-use**: login-required pages, JS-rendered content, form filling, clicking, bot-protected sites, interactive workflows
+
+## Environment Variables
+- `BROWSER_USE_API_KEY` — API key for ChatBrowserUse or cloud
+- `BU_NAME` — name for remote daemon
+- `BU_CDP_URL` — custom CDP endpoint
+- `BH_DOMAIN_SKILLS=1` — enable domain-specific skills
+- `BH_AGENT_WORKSPACE` — path to agent workspace with helpers
+
+## Recordings
+```bash
+# Enable/disable background recording
+browser-use recordings enable
+browser-use recordings disable
+
+# View latest recording
+browser-use recordings --latest
+```
+
+## Common Use Cases
+- Fill job applications with resume data
+- Extract structured data from websites (followers, products, prices)
+- Compare prices across multiple sites
+- Automate checkout flows
+- Screenshot pages for verification
+- QA testing of web applications
+- Monitor website changes
+
+## Integration with Verification Workflow
+```bash
+# After deploying an API, verify it works via browser
+browser-use <<'PY'
+new_tab("https://api.riotpiao.com/health")
+info = page_info()
+print(info)  # Should show {"status": "ok"}
+PY
+
+# Verify UI renders correctly after deployment
+browser-use <<'PY'
+new_tab("https://myapp.riotpiao.com")
+wait_for_load()
+# Check page title
+title = js("document.title")
+print(f"Page title: {title}")
+PY
+```
+
+## Gotchas
+- First navigation per task must use `new_tab(url)`, not `goto_url(url)`
+- Don't open duplicate tabs — check `list_tabs()` first
+- Login walls: stop and ask user. Exception: SSO if already signed in
+- `chrome://inspect/#remote-debugging` must be enabled for local Chrome
+- CDP target order ≠ Chrome's visible tab-strip order
+- Always call `wait_for_load()` after navigation
+- Cloud browsers bill until stopped — always `stop_remote_daemon()` when done
