[soloestoy]

introduce negative filters for CLIENT LIST and CLIENT KILL commands:

1. NOT-ID: Excludes clients in the IDs set
2. NOT-TYPE: Excludes clients of the specified type
3. NOT-ADDR: Excludes clients of the specified address and port
4. NOT-LADDR: Excludes clients connected to the specified local address and port
5. NOT-USER: Excludes clients of the specified user
6. NOT-FLAGS: Excludes clients with the specified flag string
7. NOT-NAME: Excludes clients with the specified name
8. NOT-LIB-NAME: Excludes clients using the specified library name
9. NOT-LIB-VER: Excludes clients with the specified library version
10. NOT-DB: Excludes clients with the specified database ID
11. NOT-CAPA: Excludes clients with the specified capabilities
12. NOT-IP: Excludes clients with the specified IP address

close #1936

and fix the matching algorithm for flag 'N'.

Pull Request Overview

This PR introduces comprehensive negative filtering support for CLIENT LIST and CLIENT KILL commands, adding 14 new NOT-* filter types that exclude clients matching specified criteria instead of including them. The implementation allows combining positive and negative filters for more granular client management.

Key changes:

• Added 14 new negative filter types (NOT-ID, NOT-MAXAGE, NOT-TYPE, etc.) for both CLIENT LIST and CLIENT KILL commands
• Extended the clientFilter structure to support parallel negative filtering fields
• Updated command documentation and argument definitions to reflect the new capabilities

One high level comment, but the code looked mostly good. I liked some of the other improvements you made as well.

[madolson]

I'm good, thanks!

@soloestoy it will need similar changes like #2362 right?
