feat: add llms.txt standard support for AI agent discoverability (#784)

Cherry-picked website/, scripts/generate-llms-full.sh, and deploy-docs.yml
from joyshmitz's PR. Fixed workflow to trigger on main branch instead of
docs/docusaurus-site.

Features:
- Docusaurus documentation site with llms.txt support
- Environment-variable driven config (defaults to steveyegge org)
- Automated llms-full.txt generation from docs
- GitHub Pages deployment workflow

+# Aider Integration
+
+How to use beads with Aider.
+
+## Setup
+
+### Quick Setup
+
+```bash
+bd setup aider
+```
+
+This creates/updates `.aider.conf.yml` with beads context.
+
+### Verify Setup
+
+```bash
+bd setup aider --check
+```
+
+## Configuration
+
+The setup adds to `.aider.conf.yml`:
+
+```yaml
+# Beads integration
+read:
+  - .beads/issues.jsonl
+
+# Optional: Auto-run bd prime
+auto-commits: false
+```
+
+## Workflow
+
+### Start Session
+
+```bash
+# Aider will have access to issues via .aider.conf.yml
+aider
+
+# Or manually inject context
+bd prime | aider --message-file -
+```
+
+### During Work
+
+Use bd commands alongside aider:
+
+```bash
+# In another terminal or after exiting aider
+bd create "Found bug during work" --deps discovered-from:bd-42 --json
+bd update bd-42 --status in_progress
+bd ready
+```
+
+### End Session
+
+```bash
+bd sync
+```
+
+## Best Practices
+
+1. **Keep issues visible** - Aider reads `.beads/issues.jsonl`
+2. **Sync regularly** - Run `bd sync` after significant changes
+3. **Use discovered-from** - Track issues found during work
+4. **Document context** - Include descriptions in issues
+
+## Example Workflow
+
+```bash
+# 1. Check ready work
+bd ready
+
+# 2. Start aider with issue context
+aider --message "Working on bd-42: Fix auth bug"
+
+# 3. Work in aider...
+
+# 4. Create discovered issues
+bd create "Found related bug" --deps discovered-from:bd-42 --json
+
+# 5. Complete and sync
+bd close bd-42 --reason "Fixed"
+bd sync
+```
+
+## Troubleshooting
+
+### Config not loading
+
+```bash
+# Check config exists
+cat .aider.conf.yml
+
+# Regenerate
+bd setup aider
+```
+
+### Issues not visible
+
+```bash
+# Check JSONL exists
+ls -la .beads/issues.jsonl
+
+# Export if missing
+bd export
+```
