Desktop: Session Loading & History Preservation + LAN Chat Improvements

Desktop Session Auto-Load

Bug: Desktop app created a new empty session on startup instead of
loading existing workspace sessions, even when unlocked sessions with
messages were available.

Fixes:

• Iterate all workspace sessions — EnsureSession now iterates all
  workspace sessions (newest-first) and loads the first one with actual
  messages that isn't locked by another instance, mirroring TUI behavior.
  Previously it only tried the single newest session.
• Release session lock on close — Close() now explicitly releases
  the session lock, preventing zombie locks that block other instances.
• Skip empty sessions — Auto-load skips sessions with zero messages,
  preventing stale auto-created empty sessions from taking priority.
• Agent context restoration — InitAgent now calls
  RestoreSessionIntoAgent to populate agent context with loaded session
  messages. Without this, the agent started empty and the first
  saveSession() call would overwrite the session with 1-2 messages.
• Frontend session ID fallback — ChatView self-fetches the session ID
  from the backend as a fallback when the parent's mount polling hasn't
  completed, fixing blank screen on startup.

Compaction History Preservation

Bug: Desktop app destroyed pre-compaction history when saving sessions
after compaction, because saveSession() did a full rewrite with the
agent's compacted messages (summary + recent only).

Fixes:

• Checkpoint handler — Desktop now sets a SetCheckpointHandler so
  compaction appends a checkpoint record to the JSONL file instead of
  triggering a full rewrite. This matches TUI behavior.
• Compaction-aware saveSession — saveSession() detects compaction
  (agent has fewer messages than session) and skips the full rewrite,
  only appending new digest messages to disk. In-memory ses.Messages
  is preserved so GetSessionHistory() returns the full conversation.

LAN Chat Message Rendering (Desktop)

Agent-to-agent messages injected via LAN Chat are now rendered properly:

• "LAN Chat from xxx" label — The [LAN Chat from nick]: prefix is
  parsed into a small sender label above the message, matching the
  IM/Mobile source badge pattern.
• Injection prefix stripped — The "New user guidance arrived while
  you were working..." prefix is removed from display.
• Markdown rendering — LAN Chat messages now render as markdown
  instead of plain text.
• Receipt suppression — Delivery receipts for agent-to-agent messages
  are no longer shown in the chat panel.

lanchat Tool Improvements

as_agent defaults to true — The lanchat tool is almost always
called by the agent itself, so as_agent now defaults to true. The LLM
no longer needs to explicitly pass as_agent=true on every call. Setting
as_agent=false explicitly still works for forwarding messages as the
human user.

to_role defaults to agent — When as_agent is true (the default),
to_role also defaults to agent, ensuring agent-to-agent delivery.

Team-scoped broadcast — broadcast now sends to your own team members
only (respects team isolation). New broadcast_all action sends to
everyone on the LAN.

Multi-recipient DM — send accepts comma-separated node IDs:

lanchat(action='send', to='id1,id2,id3', message='...')

TUI Improvements

• Markdown rendering — Agent-to-agent messages and history loading
  now use chatWriteUserMarkdown for proper markdown rendering.
• Team-scoped broadcast — The /chat broadcast command now sends to
  team members only.
