Update kind numbers to 34235 (normal videos) and 34236 (short videos)

Extends NIP-71 to support addressable video events for content that may need updates after publication. This enables:

- Metadata corrections without republishing
- URL migration when hosting changes
- Preservation of imported content IDs from legacy platforms
- Platform migration tracking

Adds kinds 32221 (normal videos) and 32222 (short videos) with required 'd' tag for unique identification and optional 'origin' tag for tracking imported content.

+## Protected events
+
+Events sent to a group MAY include the [NIP-70](70.md) `-` tag to mark them as protected events. This ensures that group messages can only be published to the intended relay by their original authors, preventing unauthorized republishing to other relays and maintaining the integrity of group discussions within their designated relay. This provides an alternative or additional method to timeline references for keeping group messages from being taken out of context.

 ## Timeline references
 
 In order to not be used out of context, events sent to these groups may contain references to previous events seen from the same relay in the `previous` tag. The choice of which previous events to pick belongs to the clients. The references are to be made using the first 8 characters (4 bytes) of any event in the last 50 events seen by the user in the relay, excluding events by themselves. There can be any number of references (including zero), but it's recommended that clients include at least 3 and that relays enforce this.

+## Addressable Video Events
+
+For content that may need updates after publication (such as correcting metadata, descriptions, or handling URL migrations), addressable versions are available:
+
+- Kind `34235` for _addressable normal videos_
+- Kind `34236` for _addressable short videos_
+
+These addressable events follow the same format as their regular counterparts but include a `d` tag as a unique identifier and can be updated while maintaining the same addressable reference. This is particularly useful for:

+- Metadata corrections (descriptions, titles, tags) without republishing
+- Preservation of imported content IDs from legacy platforms
+- URL migration when hosting changes
+- Platform migration tracking
