Changes:

• New flag format: Changed from --log level:debug to --log level=debug
• Structured filters: Changed from --log filter:msg=error to --log filter.include.msg=error
• Level field rename: Changed level: to lvl: in config for consistency
• Consistent syntax: All log options now use dot notation for hierarchy and equals for values
• Added constants: Defined all log flag constants for maintainability
• Updated parsing: Refactored PrepareLogger to handle new structured format
• Fixed bugs: Resolved issues with multiple filter options not being applied correctly

Examples:

Old flag format (deprecated):

--log level:debug
--log file:/tmp/tracee.log  
--log aggregate:5s
--log filter:msg=error,pkg=core
--log filter-out:lvl=debug

New flag format:

--log level=debug
--log file=/tmp/tracee.log
--log aggregate.enabled=true --log aggregate.flush-interval=5s
--log filters.include.msg=error --log filters.include.pkg=core
--log filters.exclude.lvl=debug

Old config format (deprecated):

log:
  level: debug
  file: /tmp/tracee.log
  filters:
    msg: [foo, bar]
    level: [error]
  filter-out:
    level: [debug]

New config format:

log:
  level: debug
  file: /tmp/tracee.log
  filters:
    include:
      msg:
        - foo
        - bar
      lvl:
        - error
    exclude:
      lvl:
        - debug

Testing: All existing tests updated + comprehensive test coverage for new format.
