feat(GhoulApp): add activity

[bluenchanter]

Description

Adds a new Activity for GhoulApp a character creation and chronicle management application for Vampire: The Masquerade.

Activity provide page-specific Discord Rich Presence for:

• Character creation and character sheets
• Rules wiki and dice tools
• Community pages
• Chronicle dashboards
• Storyteller tools
• NPCs, maps, relationships, battles, boons and experience
• Live sessions and session broadcasts

Settings

• Show chronicle name
• Show edition
• Show table role

Testing

• Tested using PreMiD's Load Build Activity workflow
• Tested across general, character, chronicle and live-session pages
• Production build and lint validation completed successfully

Implementation note

GhoulApp exposes a read-only JSON bridge on the current page so the Activity can receive stable, privacy-controlled context without scraping private UI content. The Activity does not modify the website or make external network requests.

Acknowledgements

• I read the Activity Guidelines
• I linted the code
• The PR title follows the repository's commit conventions
