v0.1.0 — OpenCode v2 support

v0.1.0 — OpenCode v2 support

The main line is now built for the OpenCode 2 plugin API.

Breaking

• Requires OpenCode 2.0.20+. On OpenCode 1.x the host's engines.opencode
  check refuses to load this version — stay on 0.0.3 (frozen v1 branch).

What's new

• Dual-surface plugin: server entry (.) purges session tasks on session.deleted;
  TUI entry (./tui) provides the live "My Backlog" sidebar panel.
• Six dialog-driven commands (/todo-add, /todo-run, /todo-remove,
  /todo-edit, /todo-list, /todo-clear) via TUI keymap commands — in /
  autocomplete and the command palette, no stubs, no model turns.
• Session-scoped tasks with per-session numbering and confirmation-based clear.
• New demo recording (Solarized Light), shipped in the npm tarball.
