v2.6.0

Chat-surface polish: the conversation survives a window reload, light themes are readable, the keybindings no longer fight VS Code's defaults, Esc stops a run, "New chat" keeps your CLI (and MCP servers) warm, and the permission card shows every option the agent offers.

Added

• Esc stops an in-flight run from the chat input — mirrors the Stop button.
• Reject-always in the permission card. The card now renders the actual
  option set the CLI offers (Allow once / Allow for this session / Reject /
  Reject for this session) instead of a hardcoded three, so a future CLI
  option shows up with no extension change.

Changed

• "New chat" no longer respawns the CLI. It now opens a fresh session on
  the running process, so warm MCP servers stay up and there's no relaunch
  lag — the CLI already supports multiple sessions per process.

Fixed

• Your conversation comes back after a window reload. The CLI re-attaches
  the previous session server-side, but the webview rendered blank — so it
  looked like the chat was lost while the agent still had the full context.
  The transcript is now replayed on reconnect ("Restored previous chat").
• Readable on light themes. ~30 hardcoded translucent-white surfaces and a
  dark code-block background painted white-on-white (and dark-on-light code) on
  light themes. They now use VS Code theme tokens (--vscode-*), so code,
  diffs, borders, and buttons adapt to whatever theme you run.
• Keybindings stop shadowing VS Code defaults. ⌘⇧C (open chat) collided
  with "Open New External Terminal" and ⌘⇧X (send selection) collided with
  the Extensions view; both moved to ⌘⌥-based shortcuts (⌘⌥C / ⌘⌥X).
