fix: normalize maestro loading ellipsis

[thymikee]

Summary

Normalize Unicode ellipsis in Maestro loading text before comparing loading gates, removing the CodeQL identity replacement flagged in security alert 16.

Adds a regression test covering the elapsed Loading… gate path when allowAlreadyPastLoading is enabled.

Closes https://github.com/callstackincubator/agent-device/security/code-scanning/16

Validation

Verified with formatting, the focused Maestro runtime assertion test, and the quick lint/typecheck bundle:

• pnpm format
• pnpm exec vitest run src/compat/maestro/__tests__/runtime-assertions.test.ts --project unit
• pnpm check:quick

Touched-file count: 2. Scope stayed within the Maestro compatibility assertion module and its test.
