Narrly release notes

Added private, narrative-native Mutations analysis across Platform and Mobile. The Mutation Halo maps 3–8 potential or evidence-backed observed variants around the canonical Narrative ID, with server-computed gravity, accessible detail views, public-remix lineage, and stress-test refresh.

Added narrative-native Turning Points analysis across Platform and Mobile: generated and existing Narrlys are analyzed by canonical Narrative ID, results live inside narrative preview/detail, and approved sharper turns update the owned narrative. External text, DOCX, and PDF analysis remains available as a secondary draft tool.

Added Tribe-native Constellations beta for explainable, steward-approved discovery across three or more autonomous public Tribes, surfaced inside Tribes with difference-preserving explanations and leave, mute, correction, and report controls.

Added canonical narrative lifecycle analytics IDs across generation, publishing, viewing, sharing, and remix flows.

Added collision-safe friendly public narrative URLs, narrative-specific social metadata, and a dry-run-first legacy slug backfill.

Added an automated public Release Notes page sourced from this changelog.

Improved production dependency security by clearing the critical advisories that were present in the prior stack.

Fixed the signed-out public narrative viewer crash and friendly-route live subscription lookup.

Fixed web publication failing with Firestore permission errors by moving slug reservation and public-mirror writes behind the authenticated server publisher.

Fixed homepage, canceled-checkout, and email-verification prerendering on the patched Next.js release.

Added Master Plots API support for creating narrative arcs and resuming them with chapters.

Added public-safe Discover User Search support for profile lookup by name.

Added Pro-gated Custom Integrations API support for HTTPS webhook connections.
