feat: improve Unreal Insights live analysis

[AiMiDi]

Description

Improve the existing Unreal Insights harness while keeping the harness/package version at v1 (0.1.0).

This adds Trace Store discovery, live UE process helpers with a pluggable command backend, GUI open/status helpers that keep Unreal Insights running, and analyze summary for timing/counter exports. It also fixes UnrealInsights exporter filter quoting so wildcard filters such as --timers=* and --counter=* are passed as usable FParse::Token values instead of escaped literals.

Fixes N/A

Type of Change

• New Feature - adds new functionality to an existing harness or the plugin
• Bug Fix - fixes incorrect behavior
• Documentation - updates docs only

For Existing CLI Modifications

• All unit tests pass: python -m pytest cli_anything/unrealinsights/tests/test_core.py -q
• All E2E tests pass: python -m pytest cli_anything/unrealinsights/tests/test_full_e2e.py -q -s -rs --tb=short
• No test regressions - no previously passing tests were removed or weakened
• registry.json entry is updated if version, description, or requirements changed (not changed; version remains 0.1.0 / v1 by intent)

General Checklist

• Code follows existing patterns and conventions
• --json flag is supported on any new commands
• Commit messages follow the conventional format (feat:, fix:, docs:, test:)
• I have tested my changes locally

Test Results

Local environment:

• Windows
• Unreal Insights: D:\Program Files\Epic Games\UE_5.5\Engine\Binaries\Win64\UnrealInsights.exe, version 5.5.4
• Unreal Trace Server: D:\Program Files\Epic Games\UE_5.5\Engine\Binaries\Win64\UnrealTraceServer.exe, version 5.5
• Real sample trace auto-discovered from UE install: example_trace.decomp.utrace
• UNREALINSIGHTS_TEST_TARGET_EXE was not set, so real capture-launch E2E remains skipped

Commands run:

python -m pip install -e .
python .github\scripts\validate_root_skills.py
Root skills validation passed.

SKIPPED [1] cli_anything\unrealinsights\tests\test_full_e2e.py:236: UNREALINSIGHTS_TEST_TARGET_EXE not set or missing
14 passed, 1 skipped in 80.60s (0:01:20)

Skip note: the single skipped test is the env-gated capture-launch test requiring a user supplied UE/game executable. The real exporter/analyze sample trace tests pass locally, including timing-events, timer-stats, timer-callees, and counter-values.

Thanks for the Unreal Insights work. I did not find a hard blocker in the code review, but I would adjust live.list_unreal_processes() so include_tools=True does not drop Unreal-related processes whose role is still unknown; discovery is more useful if those are visible with role: "unknown".

The remaining review risk is real-tool behavior with UNREALINSIGHTS_LIVE_EXEC, TraceServer, and live UE processes.
