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

+# Wisps
+
+Wisps are ephemeral workflows that don't sync to git.
+
+## What are Wisps?
+
+Wisps are "vapor phase" molecules:
+- Stored in `.beads-wisp/` (gitignored)
+- Don't sync with git
+- Auto-expire after completion
+- Perfect for temporary operations
+
+## Use Cases
+
+| Scenario | Why Wisp? |
+|----------|-----------|
+| Local experiments | No need to pollute git history |
+| CI/CD pipelines | Ephemeral by nature |
+| Scratch workflows | Quick throwaway work |
+| Agent coordination | Local-only coordination |
+
+## Creating Wisps
+
+```bash
+# Create wisp from formula
+bd wisp create <formula> [--var key=value]
+
+# Example
+bd wisp create quick-check --var target=auth-module
+```
+
+## Wisp Commands
+
+```bash
+# List wisps
+bd wisp list
+bd wisp list --json
+
+# Show wisp details
+bd wisp show <wisp-id>
+
+# Delete wisp
+bd wisp delete <wisp-id>
+
+# Delete all completed wisps
+bd wisp cleanup
+```
+
+## Wisp vs Molecule
+
+| Aspect | Molecule | Wisp |
+|--------|----------|------|
+| Storage | `.beads/` | `.beads-wisp/` |
+| Git sync | Yes | No |
+| Persistence | Permanent | Ephemeral |
+| Use case | Tracked work | Temporary ops |
+
+## Phase Control
+
+Use `bd mol bond` to control phase:
+
+```bash
+# Force liquid (persistent molecule)
+bd mol bond <formula> <target> --pour
+
+# Force vapor (ephemeral wisp)
+bd mol bond <formula> <target> --wisp
+```
+
+## Example: Quick Check Workflow
+
+Create a wisp for running checks:
+
+```toml
+# .beads/formulas/quick-check.formula.toml
+formula = "quick-check"
+description = "Quick local checks"
+
+[[steps]]
+id = "lint"
+title = "Run linter"
+
+[[steps]]
+id = "test"
+title = "Run tests"
+needs = ["lint"]
+
+[[steps]]
+id = "build"
+title = "Build project"
+needs = ["test"]
+```
+
+Use as wisp:
+
+```bash
+bd wisp create quick-check
+# Work through steps...
+bd wisp cleanup  # Remove when done
+```
+
+## Auto-Expiration
+
+Wisps can auto-expire:
+
+```toml
+[wisp]
+expires_after = "24h"  # Auto-delete after 24 hours
+```
+
+Or cleanup manually:
+
+```bash
+bd wisp cleanup --all  # Remove all wisps
+bd wisp cleanup --completed  # Remove only completed
+```
+
+## Best Practices
+
+1. **Use wisps for local-only work** - Don't sync to git
+2. **Clean up regularly** - `bd wisp cleanup`
+3. **Use molecules for tracked work** - Wisps are ephemeral
+4. **Consider CI/CD wisps** - Perfect for pipeline steps
