refactor(builders)!: use full predicates and disable nested validation

[Copilot]

Please describe the changes this PR makes and why it should be merged:

Nested validation in chat input commands caused redundant validation passes. Parent predicates only validated structure (type fields), requiring children to validate their own properties.

Changes

Predicates now validate complete nested structures:

• Created fullBasicOptionPredicate validating all option properties (name, description, choices, autocomplete, min/max values, channel types)
• Created fullSubcommandPredicate validating subcommands with nested options
• Created fullSubcommandGroupPredicate validating subcommand groups with nested subcommands
• Updated chatInputCommandPredicate, chatInputCommandSubcommandPredicate, and chatInputCommandSubcommandGroupPredicate to use full predicates

Parent toJSON() methods now pass false to children:

• ChatInputCommandBuilder.toJSON() passes false to nested options (line 33)
• ChatInputCommandSubcommandGroupBuilder.toJSON() passes false to subcommands (line 77)
• ChatInputCommandSubcommandBuilder.toJSON() passes false to options (line 110)

Result

Each structure validates once at parent level. Top-level validationOverride parameter still controls validation behavior—only internal nesting is affected.

Status and versioning classification:

• Code changes have been tested against the Discord API, or there are no code changes
• I know how to update typings and have done so, or typings don't need updating
• This PR only includes non-code changes, like changes to documentation, README, etc.

Warning

Firewall rules blocked me from connecting to one or more addresses (expand for details)

I tried to connect to the following addresses, but was blocked by firewall rules:

• downloads.rclone.org
  • Triggering command: /usr/local/bin/node node bin/rclone.js selfupdate (dns block)

If you need me to access, download, or install something from one of these locations, you can either:

• Configure Actions setup steps to set up my environment, which run before the firewall is enabled
• Add the appropriate URLs or hosts to the custom allowlist in this repository's Copilot coding agent settings (admins only)
