* Fix base and update batch handoff
* Improve PKG Manager startup diagnostics and scan ordering
* Update development and release ELF names
* bump version to 1.2.3
* Trim PS5 startup imports and add early stdout markers
* Add guided Samba share/folder picker with credential-aware browse APIs
Frontend no longer requires typing share names or paths: the share
modal offers Select share / Browse folder picker dialogs backed by new
POST /api/smb/shares and /api/smb/browse endpoints (IPC$ share enum
plus directory listing in smb_client). Browse requests reuse the stored
password when the form resends it blank, avoiding guest-logon
STATUS_ACCESS_DENIED while editing saved shares.
* Update SMB management and client behavior
* fix frontend browser history navigation
* docs: prepare v1.2.3 release notes
