Align with unity-cli skill 2.0.0 (pure-skills migration). package.json
and ConsoleServiceConfig.PackageVersion both at 2.0.0.

fix: improve refresh reliability and bump version to 1.3.1

Refresh lifecycle improvements:
- Split TriggerRefresh into targeted (changedFiles) and full modes
- Targeted mode uses ImportAsset per file + RequestScriptCompilation
  only when .cs files are present
- Full mode activates editor window via SetForegroundWindow to flush
  OS file-watcher queue before AssetDatabase.Refresh
- Schedule TriggerRefresh via MainThreadRequestRunner.Post instead of
  EditorApplication.delayCall for thread safety from HTTP handlers
- Add safety timeout for Requested phase to prevent infinite hang
- Add grace period before declaring compilation-less completion
- Support changedFiles parameter in RefreshRequest contract

Version bump:
- package.json: 1.3.0 → 1.3.1
- ConsoleServiceConfig.PackageVersion: 1.3.0 → 1.3.1

feat: add prefab asset commands, DontDestroyOnLoad support, and bug f…

…ixes (v1.3.0)

Add 9 new prefab asset-level commands for direct prefab editing without
instantiation, fix DontDestroyOnLoad object visibility across all
GameObject commands, and resolve several runtime/startup bugs.

New prefab asset commands:
- prefab/asset_hierarchy: read prefab internal hierarchy tree
- prefab/asset_get: get detailed info about a GameObject in a prefab
- prefab/asset_get_component: read serialized properties of a component
- prefab/asset_modify_component: modify component fields and auto-save
- prefab/asset_add_component: add component to prefab GameObject
- prefab/asset_remove_component: remove component from prefab GameObject
- prefab/asset_modify_gameobject: modify GO properties (name/tag/layer/active)
- prefab/asset_add_gameobject: add child GameObject to prefab
- prefab/asset_remove_gameobject: remove child GameObject from prefab

DontDestroyOnLoad support:
- gameobject/find now searches DontDestroyOnLoad scene in play mode
- FindByPath falls back to DontDestroyOnLoad roots
- scene/hierarchy includes dontDestroyOnLoadRoots in response

Bug fixes:
- Service startup now writes refresh_state.json immediately so direct
  launch discovery works without waiting for a refresh cycle
- /reload now clears _RUNTIME_DEFINE_LINE_OVERRIDE so runtime defines
  are re-read from file instead of using stale cached values
- /reload restores original local runtime_defines_path to prevent
  remote compile server paths from persisting after cache reset
- Allow exiting playmode while editor is compiling

Breaking changes:
- selection.get response changed from instanceIds[]+assetPaths[] to
  objects[] with name, typeName, assetPath, hierarchyPath per object
- scene/hierarchy response adds dontDestroyOnLoadRoots field

Refactoring:
- Extract SerializedPropertyToString, TrySetSerializedProperty, PropertyInfo,
  and FieldPair from ComponentCommandActions to CommandHelpers for reuse
- Add LoadPrefabAsset, ResolvePrefabGameObject, GetPrefabRelativePath
  helpers to CommandHelpers

chore: sync PackageVersion constant to 1.2.0

Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

feat: command framework cleanup and cross-repo optimization pass

Part 1 — Command framework refactor:
- Clean up command framework and fix handler bugs

Part 2 — Cross-repo optimization:
- Tuple keys in ReplServiceRegistry to prevent session key collision
- Main-thread reentrance detection to prevent deadlock
- Command discovery retry with 10s cooldown
- Health endpoint version info (packageVersion, protocolVersion, unityVersion)
- /batch endpoint for sequential multi-command execution
- List<T> parameter support in command argument binding
- Configurable timeouts via ConsoleServiceConfig
- Session idle expiry (6h) in ReplServiceRegistry
- /refresh endpoint PlayMode integration (fire-and-forget)
- Consolidate transport_http.py post functions
- Extract timeout constants in client_base.py
- Use type constants in response_parser.py
- Add repository, keywords, bugs to package.json

Part 3 — Bug fixes & improvements:
- Support positional arguments in command parser
- Rename hyphenated commands to underscores (scene_view, game_view, set_parent)
- Thread-safe timestamps via Stopwatch (ServiceTimestamp)
- EvictIdleSessions: snapshot collection before iterating
- exitPlayModeRequested: fire-and-forget semantics
- Updated README, README_zh, ExtendingCommands docs
