- Update of rootfile
- Changelog
    6.0.2
	- Support for per-CPU SAs (RFC 9611) has been added (Linux 6.13+).
	- Basic support for AGGFRAG mode (RFC 9347) has been added (Linux 6.14+).
	- POSIX regular expressions can be used to match remote identities.
	- Switching configs based on EAP-Identities is supported. Setting
	  `remote.eap_id` now always initiates an EAP-Identity exchange.
	- On Linux, sequence numbers from acquires are used when installing SAs. This
	  allows handling narrowing properly.
	- During rekeying, the narrowed traffic selectors are now proposed instead of
	  the configured ones.
	- The default AH/ESP proposals contain all supported key exchange methods plus
	  `none` to make PFS optional and accept proposals of older peers.
	- GRO for ESP in enabled for NAT-T UDP sockets, which can improve performance
	  if the esp4|6_offload modules are loaded.
	- charon-nm sets the VPN connection as persistent, preventing NetworkManager
	  from tearing down the connection if the network connectivity changes.
	- ML-KEM is supported via OpenSSL 3.5+.
	- The wolfssl plugin is now compatible to wolfSSL's FIPS module.
	- The libsoup plugin has been migrated to libsoup 3, libsoup 2 is not supported
	  anymore.
	- The long defunct uci plugin has been removed.
	- Log messages by watcher_t are now logged in a separate log group (`wch`).
