feat(session): integrate kugetsu_context_dump into delegation flow

- Call kugetsu_context_dump() in cmd_start() before forking agent
- Call kugetsu_context_dump() in cmd_continue() before forking agent
- Captures initial user prompt in context JSON for session resumption

+Commands:
+    init        Create base + pm-agent sessions via TUI. Requires terminal access.
+                Use --force to reinitialize if sessions exist.
+    start       Fork new session from base for specific issue.
+                Requires pm-agent to be running (created by init).
+    continue    Continue work on existing issue session.
+    delegate    Send message to PM agent for task coordination.
+                Fire-and-forget: returns immediately, runs in background.
+                Use 'kugetsu logs' to check output.
+    logs        Show recent delegation logs.
+                Default: 10 most recent. Use 'kugetsu logs 20' for more.
+    status      Check if kugetsu is initialized and PM agent is active.
+    doctor      Diagnose kugetsu issues. Use --fix to attempt repairs.
+    notify      Show or clear notifications from PM agent.
+                Use 'kugetsu notify list' to see unread notifications.
+    list        Show all sessions (base + pm-agent + forked issues).
+    prune       Remove sessions not in index (orphaned from opencode).
+                Use --force to skip confirmation.
+    destroy     Delete specific issue, pm-agent, or base session.
 
-Usage:
-    kugetsu queue [subcommand]
+Options:
+    --debug   Show real-time debug output and capture to debug.log

-    clear                                              Clear all queue items
-    enqueue <issue-ref> <message>                      Enqueue a task

+PM Context:
+    kugetsu reads ~/.kugetsu/pm-agent.md (if exists) and injects it
+    into the PM agent session at init time. This allows customizing PM
+    behavior without recreating the session.
+
+Notifications:
+    PM Agent writes task completion notifications to ~/.kugetsu/notifications.json
+    Use 'kugetsu notify list' to see unread notifications.
 
 Examples:
-    kugetsu queue list
-    kugetsu queue stats
-    kugetsu queue clear
-    kugetsu queue enqueue github.com/shoko/kugetsu#14 "fix bug"
