    Player Metadata Utilities Module
    ----------------------------------
    This module provides functions for retrieving and setting metadata for players
    across different frameworks (QB, ESX, OXCore). It also registers server callbacks
    for getting and setting metadata.

-------------------------------------------------------------
-- Player Retrieval
-------------------------------------------------------------

--- Retrieves the player object using the active core export.
---
--- @param source number The server ID of the player.
--- @return table|nil table The player object, or nil if no supported core is detected.
---
--- @usage
--- ```lua
--- local player = GetPlayer(playerId)
--- ```
function GetPlayer(source)
    if isStarted(QBExport) then
        debugPrint("^6Bridge^7: ^3GetPlayer^7() QBExport")

-------------------------------------------------------------
-- Metadata Retrieval
-------------------------------------------------------------

--- Retrieves metadata from a player object.
---
--- If called client-side (player is nil), it triggers a server callback to retrieve metadata.
---
--- @param player table|nil The player object; if nil, metadata is retrieved via a server callback.
--- @param key string The metadata key to retrieve.
--- @return any The value of the requested metadata, or nil if not found.
---
--- @usage
--- ```lua
--- local myMeta = GetMetadata(player, "myKey")
--- ```

-- Metadata Setting
-------------------------------------------------------------

--- Sets metadata on a player object.
---
--- The function updates the player's metadata using the active core export.
---
--- @param player table The player object.
--- @param key string The metadata key to set.
--- @param value any The new value for the metadata key.
---
--- @usage
--- ```lua
--- SetMetadata(player, "myKey", "newValue")
--- ```
