Release v0.0.2

Bundles the in-flight work into the second tagged release. See
CHANGELOG.md `[0.0.2] - 2026-05-15` for the full per-change list.
Highlights:

- libghostty-vt was building in zig's silent Debug default, capping
  the full pipeline at 34-63 fps. Makefile now defaults to
  ReleaseFast (.mise.toml pins zig 0.15.2 so the build is
  reproducible). End-to-end pipeline now runs at 930-2030 fps —
  27-32× faster, with 7-16× headroom over a 120 fps target.
- --debug[=DIR] and --profile[=DIR] flags capture full PTY logs,
  pprof data, and per-hot-path metrics (chunks/sec, mean/max
  latencies, cache hit rates) for offline analysis. Nothing
  pollutes stdout/stderr.
- ASCII-video benchmark suite (8-colour / truecolor / Bad-Apple
  patterns at 30/60/120 fps) plus a renderer microbenchmark set
  for stable A/B comparisons across changes.
- Click-and-drag text selection from alt-screen TUIs (codex) now
  works — host mouse mode follows the focused child's screen side
  instead of being permanently armed.
- Long claude session resume + codex steady-state rendering pay
  less per chunk: drawSidebar deferred to the chrome ticker,
  emulator.Title CGO poll gated on a containsOSC scan.
- Vendor-TUI orientation: MCP initialize.instructions, the
  spawn_agent tool description, and help('spawning') all spell
  out the anti-patterns (shell-out, perl-into-socket) that
  produced codex's stray top-level tabs.
