VERSE f37f0681ce feat: better debugger (#13)
- create centralized structured logger with rotation
(https://github.com/versenilvis/IRIS/commit/96ad7c95ef0f7a9957b1bbf70bb6c8da3ce28b2e)
- update core lookup and utils to use new logger
(https://github.com/versenilvis/IRIS/commit/8b74b5a9cdc1828cff8c6d0bdaaccbe31da7a00a)
- add log startup metadata and propagate reload flags
(https://github.com/versenilvis/IRIS/commit/31208aa91a58e9e09abbf5497c314f5c961a58e2)
- add log key interceptions and pty events
(https://github.com/versenilvis/IRIS/commit/91ccb92835dd16ee70bf630fe0f267aad93c9db0)
- add test for logger 221a40c893b75e6215787163cd751a4c1cb6c1d8
- secure reload arguments file path to prevent symlink attacks
(https://github.com/versenilvis/IRIS/pull/13/commits/c3eabfda451230e52cb71f0c2a556687f839bd3f)
- close log file on reinitialization to prevent descriptor leak
(https://github.com/versenilvis/IRIS/pull/13/commits/a57d2c9be107a8c6200cf7046cc85b2f58667dce)
