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.

 ### Fixed
+- Tab bar redraw used `\x1b[2K` to clear rows 1 and 2 before painting
+  labels, which wiped the sidebar columns on those rows too. When the
+  sidebar cache was still warm the rail never repainted, leaving a
+  gap where the sidebar's top border and "Processes" header should be.
+  The clear is now bounded to the viewport width.
+- Long-running TUIs (claude / codex) whose internal column state
+  drifted past the patterm viewport could spray text into the sidebar
+  columns — overwriting the session-tree and scratchpad rail until the
+  user opened/closed the palette to force a full repaint. The viewport
+  renderer now clamps absolute cursor positioning (CUP / HVP / CHA /
+  HPA) to the viewport's right edge and drops printable bytes (ASCII
+  and full UTF-8 glyphs) that would otherwise land past it. Covered by
+  a unit suite and a new `sidebar_survives_wide_writes` harness
+  scenario.
 - Sub-agent panes spawned while another diff-based TUI (claude/codex/
   opencode) held focus could come up corrupted because the new child's

+### Changed
+- Command palette `Kill …` entries now mark the focused tab with the
+  same "• … (current)" marker the `Switch to …` entries use, so the
+  user can tell at a glance which tab a kill action targets.
+- Status line now advertises the navigation chords (`Ctrl-A/D · tabs`,
+  `Ctrl-W/S · tree`) alongside `Ctrl-K · palette`. Hints decay
+  shortest-first when the terminal is too narrow to fit all three.

 ### Added
+- "Spawn process…" entry in the command palette opens a two-field form
+  for typing an arbitrary command line and ticking "Relaunch on exit".
+  The command runs through `sh -lc` so multi-word lines like
+  `bun run dev` resolve binaries the way an interactive shell would.
+  When the relaunch flag is set, patterm Starts the process again after
+  it exits (1s backoff). Killing the process from the palette clears
+  the flag so it does not come back.
+- Dedicated "Processes" section in the sidebar above the agent tree,
+  listing every top-level command/terminal process. It is global to
+  the patterm session — switching between agent tabs no longer changes
+  which processes are visible. The relaunch-on-exit indicator (`⟳`)
+  shows next to processes the user opted into auto-restart for.
+- Ctrl+W / Ctrl+S now traverse the combined Processes section and the
+  active agent tree as one flat list, so the user can step out of the
+  agent tree into the Processes pane and back without leaving the
+  keyboard.

 ### Changed
+- The sidebar's session-tree section is now labeled "Agent Tree" and
+  shows only agent sessions (and any sub-agents they spawn). Top-level
+  command and terminal processes live in the new "Processes" section
+  above it.
+- Tab bar tabs now correspond to agent sessions only. Command/terminal
+  processes that previously claimed a top-level tab now appear in the
+  Processes sidebar section, so the tab strip is reserved for agent
+  context.
 - Focus, lifecycle, and repaint paths now capture terminal layout before
   taking UI state locks, reducing resize-time deadlock risk without
   changing visible behavior.
