Login: Fixed an issue where the login phase did not support the updated packet header 100 (GC_MARK_LOGIN).
Core Stability: Implemented safeguards to prevent server cores from crashing (core downer) when a negative value is used in commands, such as /m <vnum> <quantity>.
Book reading in max level: Reading skill books does not consume experience points anymore if the character has reached the maximum level (gets max level from game configuration, not a static number).
Character Selection: Corrected the display of character stats and ensured gauge bars accurately reflect the character's stats during the selection phase.
Negative HP: Ensured that a character's HP does not drop below 0 upon death.
CMakeLists for QC: Target libraries link to qc (was db).

⬆️ Feature Improvements

All compiler warnings for building in FreeBSD environments have been fixed
- Types are synced in comparisons, dynamic string building and other functions and some definitions.
- Minor performance improvements noticed in start time after changing libthecore's virtuals into atomic.
- More modern practices introduced in some parts of the codebase.
Messenger System:
- Cross-Channel/Core Friend Requests: Implemented support for sending and processing friend requests across different channels and server cores. ChatPacket notification is functional if the recipient is not found after searching all channels/cores.
- Live Status Updates: Live updates for adding/removing friend for both parties.
- Request Guarding: Added extensive validation checks to prevent:
  - Resending a request while a previous one is unanswered.
  - Sending a request to a person who has already sent an active, unanswered request to the sender.
  - Sending a friend request to an existing friend or to yourself.
  - All guard mechanisms provide translated ChatPacket notification messages and function correctly across channels and cores.
- All pending friend requests are cleared on character disconnect (teleport, logout, kick, etc...).
- A new friend request cancels all previous unanswered ones for that target.
Skill Cooldowns and States:
- Level Reset Handling: Skill cooldowns are now cleared upon a skill level reset or a skill-group reset. Works with /setsk setting horse skills levels to 0 as well.
- Togglable Skills: If a togglable skill is reset, it is automatically deactivated, and its active effect is immediately removed from the character.
- Combo Skills: Combo skill is automatically deactivate if its level is changed to 0 (/setsk).
.gitignore file: Ignoring all files and directories ending in _BAK or .BAK (case-insensitive)
