fix case sensitivity of the messageCreate command if unprefixed is true

[Daaisukidayo]

• Fixed the case where the messageCreate command was case sensitive if unprefixed was set to true
• Added MessageContent to the intents array
• Updated event version

[Daaisukidayo]

All tests performed manually in Discord using the eval command. Prefix was either ! or omitted, depending on the case being tested.

Command name casing (original bug)

• Eval test (capitalized, no prefix, unprefixed: true) - eval triggers correctly
• eval test - still triggers as expected

Prefix handling

• !eval test (matching case) - works
• Message with no prefix, while prefixed (unprefixed: false or omitted) commands exist - command does not trigger
• !e test - eval command resolves correctly via its alias e

unprefixed semantics

• eval with unprefixed: true works without a prefix
• Same command also works with the ! prefix

Argument (args) handling

• !eval test → eval receives args = ["test"] (command name correctly stripped)
• A nameless (always executable) handler matching the same message receives the full, unstripped ["eval", "test"] instead of a truncated array - confirms args are sliced independently per command rather than mutated on a shared array
• !eval with multiple consecutive spaces between tokens - whitespace collapses correctly, no empty tokens in args
