docs: update llms.txt to reflect current platform capabilities

Rewrite llms.txt to cover all features shipped through v0.9.1:
multi-project support, PR review/court, ticket integration, P2P
messaging, command aliases, and session management. Update config
paths from legacy single-project format to per-project layout at
~/.crabcode/projects/<alias>.yaml. Fix init question count (3, not 2).

+### Multi-Project
+
+Manage multiple repos from a single crabcode install. Each project gets an alias.
+
+```bash
+crab @pf ws 1            # Open workspace 1 for project "pf"
+crab @cb config          # Show config for project "cb"
+crab ws 1                # Uses default project (or detects from cwd)
+crab projects            # List all registered projects
+crab projects rm <alias> # Remove a project registration
+crab default pf          # Set default project
+```
+
+Project configs live in `~/.crabcode/projects/<alias>.yaml`. Commands auto-detect which project you're in based on cwd.
+
 ### Save & Restore Work
 
 ```bash
 crab wip save          # Save current changes
 crab wip save --restart  # Save then restart workspace
 crab wip --continue    # Restore most recent saved state
 crab wip --resume      # Interactive selection of saved states
-crab wip ls            # List all saved states
+crab wip ls            # List all saved states globally
+```
+
+### PR Review & Court
+
+Two modes for reviewing pull requests:
+
+```bash
+# Quick single-agent review
+crab review 3230                    # PR number
+crab review promptfoo#456           # Submodule PR
+crab review https://github.com/...  # Full URL
+
+# Court review - multi-agent tribunal with judge pattern
+crab court 3230                     # Judge + 2 reviewers
+```
+
+Court review uses the judge pattern: a Judge (Claude) orchestrates two independent reviewers (Claude teammate + Codex), verifies every finding against actual code, resolves disagreements, and delivers a verdict with zero false positives.
+
+```bash
+crab review ls              # List review sessions
+crab review show <PR>       # View saved review output
+crab review resume <PR>     # Resume a review
+crab review delete <PR>     # Delete a review session
+crab review delete --all    # Delete all review sessions
+```
+
+### Ticket Integration
+
+Create workspaces from Linear ticket identifiers with automatic context injection:
+
+```bash
+crab ticket ENG-123          # Provision workspace from ticket
+crab ws 3 ticket ENG-123     # Bind ticket to specific workspace
+```
+
+### P2P Messaging
+
+Peer-to-peer messaging via self-hosted relay server:
+
+```bash
+crab msg start               # Start relay server
+crab msg @user "message"     # Send message to peer
+crab msg read                # View inbox
+crab msg listen              # Real-time message stream
+crab msg say on/off          # Toggle text-to-speech for incoming messages
+crab msg history             # View message history
+crab msg stop                # Stop relay server
