Pull Request Overview

This PR adds JSON schema definitions for NIP-25 reaction events, supporting both reactions to nostr events (kind 7) and reactions to external content (kind 17). It also introduces support for custom emoji tags and external content tags from NIP-73.

• Add kind 7 and kind 17 reaction event schemas with proper validation
• Implement custom emoji tag schema for reactions with shortcode and URL validation
• Add external content identifier (i) and type (k) tag schemas from NIP-73
• Create reusable alias files for cross-schema tag references

This validation logic is redundant. The emoji tag validation is already handled in the items section (lines 17-25). This duplication could cause confusion and maintenance issues.

Suggested change

	allOf:
	- if:
	contains:
	type: array
	minItems: 1
	items:
	- const: "emoji"
	then:
	contains:
	$ref: "@/tag/emoji.yaml"

[nitpick] This inline e-tag validation should be extracted to a separate schema file for reusability, following the pattern established for other tag types.

The error messages are nested under individual 'contains' constraints, but this structure may not work as expected in JSON Schema. Consider moving the errorMessage to the top level of the allOf block for proper error handling.

Suggested change

	errorMessage:
	contains: "tags must include at least one k tag describing the external content type"
	- contains:
	$ref: "@/tag/external-content-i.yaml"
	errorMessage:
	contains: "tags must include at least one i tag referencing the external content"
	- contains:
	$ref: "@/tag/external-content-i.yaml"
	errorMessage:
	allOf:
	- "tags must include at least one k tag describing the external content type"
