[Bug]: openlogi-agent calls TCCAccessRequest for Accessibility in a rapid ~1.2s loop on macOS

### Which part of OpenLogi?
Agent

### Operating system
macOS (Apple Silicon, macOS 26.x)

### OpenLogi version
0.8.1

### Description
In macOS unified logs (`log show --predicate 'process CONTAINS "openlogi"'`), `openlogi-agent` is observed calling `TCCAccessRequest() IPC` repeatedly every ~1.2 seconds:

```text
openlogi-agent: (TCC) TCCAccessRequest() IPC
openlogi-agent: (TCC) TCCAccessRequest() IPC
tccd: [com.apple.TCC:access] TCCDProcess: identifier=org.openlogi.openlogi attempted to call TCCAccessRequest for kTCCServiceAccessibility without the recommended com.apple.private.tcc.manager.check-by-audit-token entitlement
```

### Steps to reproduce
1. Launch OpenLogi / openlogi-agent on macOS.
2. Observe system logs with `/usr/bin/log show --predicate 'process CONTAINS "openlogi"' --last 5m`.

### Expected Behavior
Accessibility status should be queried via `AXIsProcessTrusted()` / cached without continuous IPC spam to `tccd`.

Start with the openlogi-agent code that checks macOS Accessibility status, then reproduce the behavior with /usr/bin/log show --predicate 'process CONTAINS "openlogi"' --last 5m. Trace why TCCAccessRequest is called every ~1.2 seconds and verify that status uses AXIsProcessTrusted or caching without continuous IPC messages to tccd.
