* Add Cherry Studio MCP client support

* Fix misleading message in HTTP mode for Cherry Studio

* Address code review feedback

* Add editor readiness v2, refresh tool, and preflight guards

* Detect external package changes and harden refresh retry

* feat: add TestRunnerNoThrottle and async test running with background stall prevention

- Add TestRunnerNoThrottle.cs: Sets editor to 'No Throttling' mode during test runs
  with SessionState persistence across domain reload
- Add run_tests_async and get_test_job tools for non-blocking test execution
- Add TestJobManager for async test job tracking with progress monitoring
- Add ForceSynchronousImport to all AssetDatabase.Refresh() calls to prevent stalls
- Mark DomainReloadResilienceTests as [Explicit] with documentation explaining
  the test infrastructure limitation (internal coroutine waits vs MCP socket polling)
- MCP workflow is unaffected - socket messages provide external stimulus that
  keeps Unity responsive even when backgrounded

* refactor: simplify and clean up code

- Remove unused Newtonsoft.Json.Linq import from TestJobManager
- Add throttling to SessionState persistence (once per second) to reduce overhead
- Critical job state changes (start/finish) still persist immediately
- Fix duplicate XML summary tag in DomainReloadResilienceTests

* docs: add async test tools to README, document domain reload limitation

- Add run_tests_async and get_test_job to main README tools list
- Document background stall limitation for domain reload tests in DEV readme

* ci: add separate job for domain reload tests

Run [Explicit] domain_reload tests in their own job using -testCategory

* ci: run domain reload tests in same job as regular tests

Combines into single job with two test steps to reuse cached Library

* fix: address coderabbit review issues

- Fix TOCTOU race in TestJobManager.StartJob (single lock scope for check-and-set)
- Store TestRunnerApi reference with HideAndDontSave to prevent GC/serialization issues

* docs: update tool descriptions to prefer run_tests_async

- run_tests_async is now marked as preferred for long-running suites
- run_tests description notes it blocks and suggests async alternative

* docs: update README screenshot to v8.6 UI

* docs: add v8.6 UI screenshot

* docs: update v8.6 UI screenshot

* docs: update v8.6 UI screenshot

* docs: update v8.6 UI screenshot

* Update README for MCP version and instructions for v8.7

* fix: handle preflight busy signals and derive job status from test results

- manage_asset, manage_gameobject, manage_scene now check preflight return
  value and propagate busy/retry signals to clients (fixes Sourcery #1)
- TestJobManager.FinalizeCurrentJobFromRunFinished now sets job status to
  Failed when resultPayload.Failed > 0, not always Succeeded (fixes Sourcery #2)

* fix: increase HTTP server startup timeout for dev mode

When 'Force fresh server install' is enabled, uvx uses --no-cache --refresh
which rebuilds the package and takes significantly longer to start.

- Increase timeout from 10s to 45s when dev mode is enabled
- Add informative log message explaining the longer startup time
- Show actual timeout value in warning message

* fix: derive job status from test results in FinalizeFromTask fallback

Apply same logic as FinalizeCurrentJobFromRunFinished: check result.Failed > 0
to correctly mark jobs as Failed when tests fail, even in the fallback path
when RunFinished callback is not delivered.

* Bound Unity reload/session waits

* refactor: improve env var parsing and reason extraction

Address code review feedback:

- Catch ValueError specifically (instead of broad Exception) when parsing
  UNITY_MCP_RELOAD_MAX_WAIT_S, UNITY_MCP_SESSION_RESOLVE_MAX_WAIT_S, and
  UNITY_MCP_SESSION_READY_WAIT_SECONDS, with logging for easier diagnosis
  of misconfiguration

- Normalize reason values to lowercase in _extract_response_reason() to
  avoid case-sensitive mismatches in comparisons

- Simplify refresh_unity.py by removing redundant isinstance check and
  reusing _extract_response_reason instead of duplicating reason parsing

* Add upper bound clamp and custom exception for bounded retry

- Add upper bound (30s) to UNITY_MCP_RELOAD_MAX_WAIT_S to prevent
  misconfiguration from causing excessive waits
- Add upper bound (30s) to UNITY_MCP_SESSION_RESOLVE_MAX_WAIT_S for
  consistency with readiness probe
- Introduce NoUnitySessionError custom exception to replace fragile
  string matching in send_command_for_instance

Addresses code review feedback for bounded retry policy PR.

* Optimize read_console defaults and paging

* Fix read_console truncate test expectations

* Reduce read_console default count from 50 to 10

Further optimize token usage by reducing the default count from 50 to 10 entries. Even 10-20 messages with stack traces can be token-heavy. Added tests for default behavior and paging functionality. Updated tool description to document defaults and paging support.

* Fix ReadConsoleTests to include log type messages

The default types filter changed to ['error', 'warning'] (excluding 'log'), so tests using Debug.Log() need to explicitly request log messages. Also added format='detailed' to HandleCommand_Get_Works test since it accesses structured message fields.

* Address CodeRabbit review feedback

- Fix property naming consistency: next_cursor -> nextCursor (C# camelCase)
- Remove redundant EndGettingEntries call from catch block (already in finally)
- Extract stacktrace stripping to helper function (reduce duplication)
- Fix test mock to match actual C# response structure (items, nextCursor, truncated, total)

* perf: add early exit optimization for ReadConsole paging

- Add early exit in paging loop once page is filled, avoiding iteration
  through remaining console entries (total becomes 'at least N')
- Prefix unused mock arguments with underscores in test_read_console_truncate.py
  to suppress Ruff linter warnings

* refactor: give pageSize independent default, clarify count semantics

- Change pageSize resolution from 'pageSize ?? count ?? 50' to 'pageSize ?? 50'
  so pageSize has its own default independent of count
- count now only serves as the non-paging limit
- Add XML docs to GetConsoleEntries with clear parameter descriptions
- Update Python tool annotations to document pageSize default (50) and
  clarify that count is ignored when paging
