feat: unified event bus, sealed state machines, and startup verification

Introduce a unified EventBus as the single broadcast channel for all
system events, replacing the 6 disconnected event mechanisms. Seal
Thread/Turn/ContainerState fields behind private accessors with validated
transitions to prevent invalid state mutations. Fix TOCTOU races in
thread_ops and session_manager.

Event bus (src/event_bus/):
- SystemEvent envelope with EventPayload (Domain, StateChange, Telemetry,
  StateTransition, ToolExecution, AuthEvent, ConfigChange)
- Four sinks: SSE (→SseManager), audit (→DB with JSONL fallback),
  state (→StateBus), metrics (→Observer)
- AuditStore trait + implementations for PostgreSQL and libSQL
- V13 audit_log migration for both backends
- Wired into AppComponents and AgentDeps (Option<EventBus> for compat)
- Worker dual-emit through bus alongside legacy SSE+DB paths

Sealed state machines:
- Thread.state private with state() accessor, can_transition_to(),
  set_processing(), reset_to_idle()
- Turn.state private with state() accessor
- ContainerHandle.state private with new() constructor,
  mark_running/stopped/failed(), can_transition_to()
- TOCTOU fix: thread_ops moves safety validation before lock, then
  checks state + starts turn atomically under single lock
- SessionManager TOCTOU fix: atomic check-and-insert with write lock
  held for entire UUID adoption sequence

Startup verification:
- AppComponents::verify_readiness() checks component presence vs config
- ToolRegistry::verify_expected_tools() validates builtin registration
- Config::validate() checks cross-field invariants (Docker, WASM dir)

+//! Feishu/Lark Bot channel for IronClaw.
+//!
+//! This WASM component implements the channel interface for handling Feishu
+//! webhooks (Event Subscription v2.0) and sending messages back via the
+//! Feishu/Lark Bot API.
+//!
+//! # Features
+//!
+//! - Webhook-based message receiving (Event Subscription v2.0)
+//! - URL verification challenge handling
+//! - Private chat (DM) support
+//! - Group chat support with @mention triggering
+//! - Tenant access token management (app_id + app_secret exchange)
+//! - Supports both Feishu (open.feishu.cn) and Lark (open.larksuite.com)
+//!
+//! # Security
+//!
+//! - App credentials (app_id, app_secret) are injected by the host into
+//!   the config JSON during startup for token exchange
+//! - Bearer token for API calls is obtained via token exchange and cached
+//! - Verification token validated by host for webhook requests
