### Summary
* Adds `StaticNoticeGump<T>` and `StaticWarningGump<T>`
* Converts NoticeGump/WarningGump to use `DynamicGump`
* Changes various uses of notice gump and warning gump to their static counterpart.
# New Gump API
We are pleased to release a new API that is faster, allocates nearly zero memory, and still feels very similar to the original API. The API is broken into 3 types of gumps, dynamic, static with placeholders, and static without placeholders.
### Dynamic Gumps
These gumps will inherit `DynamicGump` and are meant for gumps that have a dynamic layout. This includes specifying dynamic arguments to HtmlLocalized entries.
## Static Gumps
Static gumps are those where the function to the build the layout is called only once and cached forever. They can optionally have placeholders. These placeholders allow the developer to specify the string values later, dynamically in a `BuildStrings` method on the gump. If a gump does not have any placeholders, the string entries will also be cached forever.
## Benchmarks
To make sure we were going in the right direction and not wasting time, we took copious benchmarks. Here are the final benchmarks for a really simple gump.
Note:
* The majority of creating a gump is compressing the layout and the strings. Compressing each section takes ~6,000ns (12us total).
```cs
| Method | Mean | Error | StdDev | Median | Ratio | RatioSD | Gen0 | Allocated | Alloc Ratio |

```
# Non-Breaking Changes
* All gump components in the core have been moved to `Gumps/Legacy`.
* All legacy gumps will still inherit `Gump`, which now inherits `BaseGump`
# Special Thanks
Thank you to @stefanomerotta for considerable contributions/benchmarking/testing to make this effort a reality! We collectively went through over 10 iterations, but it is finally ready.
### Summary
* Removes old gump packet support
* Removes support for v4 clients
* Removes `Unpack` flag and assumes it is always true.
* Removes StringToBuffer since this is built into .NET now.

### Summary
Fixes an issue where max items is deserialized as 0 instead of -1. To fix broken containers, run the following in-game:
`[global set maxitems -1 where container maxitems = 0`
In vanilla MUO, there are no containers that actually have max items set to 0.
### Summary
* Makes mount stamina significantly faster.
* Reduces absolute reset from 24 hours to 4 hours.
* Adds Pub 46+ Ethereal stamina where the stamina is global to all mounts for the player
* Removes serialization of stamina entirely because it's ok if it gets reset during shard restarts.
### Summary
- Fixes the name `Vegies` to `Veggies`
- Adds feeding leather to goats
- Adds metal for Lava Lizards
- Fixes Bone Helm being classified as plate instead of bone.
- Fixes wooden shields not classified as wood.
### Note
On OSI, the preferred foods on the animal lore gump doesn't contain all possible favorite food categories. Furthermore, the one listed is not necessarily always the "first" in the list of possible categories. We aren't going to try and fix that since it isn't important.
### Summary
* Adds Arya's addon generator.
* Updates it for MUO
### ToDos
* Update to use search values when .NET 9 is introduced
* Add ability to codegen basic items from data files (JSON?)
### Summary
* Fixes spawner timer deserialization
* Adds a check for a null timer and allows the timer to get recreated
* Adds PotionKeg reverse lookup
* Heavily optimizes decimal serialize/deserialize
> [!IMPORTANT]
> Please read through these changes, as they changed certain expectations for how the internal AI thinking/movement work.
> Note that some mobs still don't have smooth movement on ClassicUO due to how the client handles animations/movement.
### Summary
- **Important Change**: Mobs will now move at a more regular pace. If the OnThink results in a move, but the cooldown would otherwise prevent the move, then the movement is scheduled on another timer.
- Added a 400ms delay to mobs turning to face a player to attack in order to avoid glitching between moving and turning.
- Reverted AI thinking speeds back to RunUO specific speeds.
- Reverted the AI thinking to moving conversion delays back to RunUO.
- For thinking speeds that are not exactly the predefined speeds from RunUO, there is a new calculation to determine the correct conversion to movement speed. This stops speeds like `0.35` from being faster than `0.3`
> [!NOTE]
> **Developer Note**
> BaseAI.CheckMove() no longer contains the check for whether or not a mob is on movement cooldown. This function can now be overwritten without causing issues to figuring out that cooldown.
### Summary
- Fixes edge case calculations with values that aren't exact.
- Fixes skill text casing.
- Fixes cliloc error for stat cap scroll gump.
- Adds `AosSkillBonuses.GetLowercaseLabel()` for lower case localized skill names.
- Fixes initial value for constructing a stat scroll so it isn't negative.
- Fixes message for Scroll of Alacrity gump.
- Fixes missing property invalidation for Skill/Value.
### Summary
- Adds some more checks in case a corpse's owner is somehow null. Would like to eventually allow null owner corpses, but more work is needed.
- Cleans up variable unboxing and reassignment in quests. Also flattens quest logic. Still more work needs to be done.
- Codegens more quest items/mobiles.
> [!IMPORTANT]
> This code change includes important fixes for all spawners after they were converted to codegen!
> [!NOTE]
> **Developer Note**
> Usage/Description/Aliases attributes were moved to the core so they can be used by the command registration system.
### Summary
- **Fixes spawners not registering their spawns on world load**
- Changes `[GenerateSpawners` to `[ImportSpawners`
- Removes `ConvertPremiumSpawners`
- Adds Premium spawner import support to `[ImportSpawners`
- Adds RunUO XML import support: https://github.com/ruaduck/xmlspawner/blob/ServUOMaster/XmlSpawner/XmlSpawner%20Core/SpawnerExporter.cs
- Fixed an issue where not manually registering an alias meant it wasn't available as a command
