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

+# Beads Quick Start
+
+Get up and running with Beads in 2 minutes.
+
+## Initialize
+
+First time in a repository:
+
+```bash
+# Basic setup
+bd init
+
+# For AI agents (non-interactive)
+bd init --quiet
+
+# OSS contributor (fork workflow)
+bd init --contributor
+
+# Team member (branch workflow)
+bd init --team
+
+# Protected main branch (GitHub/GitLab)
+bd init --branch beads-sync
+```
+
+The wizard will:
+- Create `.beads/` directory and database
+- Import existing issues from git (if any)
+- Prompt to install git hooks (recommended)
+- Prompt to configure git merge driver (recommended)
+- Auto-start daemon for sync
+
+## Your First Issues
+
+```bash
+# Create a few issues
+bd create "Set up database" -p 1 -t task
+bd create "Create API" -p 2 -t feature
+bd create "Add authentication" -p 2 -t feature
+
+# List them
+bd list
+```
+
+**Note:** Issue IDs are hash-based (e.g., `bd-a1b2`, `bd-f14c`) to prevent collisions when multiple agents/branches work concurrently.
+
+## Hierarchical Issues (Epics)
+
+For large features, use hierarchical IDs to organize work:
+
+```bash
+# Create epic (generates parent hash ID)
+bd create "Auth System" -t epic -p 1
+# Returns: bd-a3f8e9
+
+# Create child tasks (automatically get .1, .2, .3 suffixes)
+bd create "Design login UI" -p 1       # bd-a3f8e9.1
+bd create "Backend validation" -p 1    # bd-a3f8e9.2
+bd create "Integration tests" -p 1     # bd-a3f8e9.3
+
+# View hierarchy
+bd dep tree bd-a3f8e9
+```
+
+Output:
+```
+Dependency tree for bd-a3f8e9:
+
+> bd-a3f8e9: Auth System [epic] [P1] (open)
+  > bd-a3f8e9.1: Design login UI [P1] (open)
+  > bd-a3f8e9.2: Backend validation [P1] (open)
+  > bd-a3f8e9.3: Integration tests [P1] (open)
+```
+
+## Add Dependencies
+
+```bash
+# API depends on database
+bd dep add bd-2 bd-1
+
+# Auth depends on API
+bd dep add bd-3 bd-2
+
+# View the tree
+bd dep tree bd-3
+```
+
+Output:
+```
+Dependency tree for bd-3:
+
+> bd-3: Add authentication [P2] (open)
+  > bd-2: Create API [P2] (open)
+    > bd-1: Set up database [P1] (open)
+```
+
+## Find Ready Work
+
+```bash
+bd ready
+```
+
+Output:
+```
+Ready work (1 issues with no blockers):
+
+1. [P1] bd-1: Set up database
+```
+
+Only bd-1 is ready because bd-2 and bd-3 are blocked!
+
+## Work the Queue
+
+```bash
+# Start working on bd-1
+bd update bd-1 --status in_progress
+
+# Complete it
+bd close bd-1 --reason "Database setup complete"
+
+# Check ready work again
+bd ready
+```
+
+Now bd-2 is ready!
+
+## Track Progress
+
+```bash
+# See blocked issues
+bd blocked
+
+# View statistics
+bd stats
+```
+
+## Database Location
+
+By default, the database is in `.beads/beads.db` (gitignored).
+
+The JSONL file `.beads/issues.jsonl` is git-tracked and syncs automatically.
+
+## Next Steps
+
+- Add labels: `bd create "Task" -l "backend,urgent"`
+- Filter ready work: `bd ready --priority 1`
+- Search issues: `bd list --status open`
+- Detect cycles: `bd dep cycles`
+- See [CLI Reference](/cli-reference) for all commands
