nntrivi2001 fa156d6a59 feat: v2.6.0 — Chat UI composer (+ menu, project files, activity panel, permission mode, Stop), git on a workspace's extra folders (#70), long paste as a file (#68), S3 server mode (experimental)
Chat UI:
- Each Claude/Codex session keeps its own chat/terminal view; Settings only
  sets how new sessions open.
- Composer + menu: upload, project files and folders (#54, also dragged from
  the Files/Changes tree), context files, recent uploads, skills, plugins.
- Activity side panel (progress, outputs, files read, uploads, memory,
  skills, connectors) with a file preview; edited-file counts per turn.
- Permission-mode chip (Shift+Tab steps, read back from the pane:
  server/lib/pane-mode.js, GET|POST /api/run/:id/permission-mode).
- Stop (Esc) while the main agent works; the status is checked per agent
  (with session_id /api/agents ignores its status filter) and re-read every
  5 s while Stop shows.
- Dropped images shown in the conversation (GET /api/run/drop/:name, the
  requester's own drop dir), full-size viewer.
- A plain-text paste over 5,000 characters is attached as pasted-text.txt,
  so no prompt reaches tmux/argv limits (#68).

Changes panel: every /api/lanes/:id/git* route takes ?source=<lane_sources
id> (sourceFolder; ENOSOURCE otherwise) and a folder picker switches the
whole panel to a workspace's extra folder (#70).

Server mode S3 (one Linux user per account) — experimental, verified with
fake sudo plus a P6 managed-settings spike on a test account:
- member tmux listing runs in the background (cached, 15 s => unknown);
- transcript snapshot copy is async, chunked, temp file + rename;
- Express Layer patch only on Express 4;
- tmux capturePane/sendKey go to the member's own server.

Docs: the multi-user design moved in as docs/plans/server-mode/README.md
(the AgentHub-Server repo is gone); S3-PLAN P6 result; LANES/API/openapi.

/**
* @file panePaste.ts — lets another part of the Workspace page paste text into
* a workspace's terminal (a diff-line comment from the Changes panel). Every
* mounted TerminalView registers its run id; the text goes to the pane of that
* workspace focused last — clicked into, or made the Workspace's focused pane
* (a tab, Alt+1–4, the sidebar) — else any of its panes. It is a paste —
* bracketed, so `claude` takes it as one block in its composer — and never an
* Enter: the user reads it and sends it. Only a pane on SCREEN takes it (one
* hidden behind a full-width Changes panel or a replay would swallow it
* unseen); the caller says where it went, or that it went nowhere. The one
* exception is `submitToRun`: a pane's own Chat view (`PaneChat.tsx`) sends
* what the user typed there, so it pastes AND presses Enter — and its Stop
* button presses Esc through `interruptRun`.
