Changelog for tuispec-0.2.0.0

Changelog

Add waitForStable primitive (DSL + JSON-RPC) to replace fixed sleeps with debounce-based viewport stability checks.
Overhaul SKILL.md around a golden-path workflow using waitForStable, with a wait-strategy decision guide and common failure troubleshooting.
Introduce server v2 APIs including launch cwd/nullable env, per-call ambiguity control, filtered currentView, render-in-one-step snapshot flows, notifications, batch operations, and JSONL recording/replay.
Add tuispec replay CLI command and expand end-to-end protocol coverage in tests and docs.
Record viewport frames in JSONL sessions and replay them on the terminal with tuispec replay, using delta compression for efficient frame storage. Keyframe and delta metadata are preserved through replay for frame reconstruction.
Add interactive replay controls: Space to pause/resume, Left/Right to step frames, Up/Down to skip 5 frames, r to redraw from last keyframe, q to quit.
Add --show-input replay flag to display the last input action on a status line below the viewport.
Add --version flag to the CLI.
Include tuispec version in initialize response and snapshot meta.json.
Fix theme-aware color rendering for light/dark PNG snapshots.
Use alternate screen buffer for replay to avoid polluting terminal scrollback.
Fix test flakiness caused by orphaned PTY child processes between server tests.

Fix PTY teardown to avoid hangs when waiting for child exit by using bounded getProcessExitCode polling.
Add regression coverage and documentation clarifying that selector matching runs on rendered viewport text (ANSI control/style escapes are interpreted).

Add optional env parameter to launch (DSL + JSON-RPC) to override process environment variables.
Add app constructor helper and update docs/examples to use it.
