Release v0.0.1

Bundles the in-flight work into the first tagged release. See
CHANGELOG.md `[0.0.1] - 2026-05-14` for the full per-change list.
Highlights:

- Sidebar / chrome stability: clamp absolute cursor positioning and
  printable bytes to the viewport so long-running TUIs (claude, codex)
  can't spray into the right rail; bound tab bar's row clear to the
  viewport width so the rail isn't wiped on every tab redraw; flag
  scroll escapes (RI/IND/NEL/SU/SD/IL/DL) and clamp `CSI 0/1/2 J`/`K`
  to viewport columns.
- Palette: "Spawn process…" form, macros (`sw `, `k `, `sp `), kill
  entries mark the focused tab, dead agents drop out of the switch
  list.
- Sidebar: split into Processes (session-wide) + Agent Tree
  (per-active-agent) sections; relaunch indicator; Ctrl+W/S walks the
  combined list, Ctrl+A/D steps tabs.
- MCP: protocol handshake (`initialize`, `tools/list`, `tools/call`,
  `ping`), `mcp_injection.kind = cli_override / config_env` so codex
  and opencode pick up the server with no file writes, `lifecycle`
  help topic and tool-description cleanup-duty pointers.
- Lifecycle: orchestrator-spawned children cascade-killed when the
  parent dies; orchestrator-injected prompts end with CR + delayed
  Enter so claude submits cleanly.
