NX Recall 0.13.1

NX Recall is a local conversation memory for VR and voice chat: multilingual
transcription, persistent speaker identity, semantic search, desktop captions,
replay, and an optional local memory graph. Capture is default-deny, and normal
capture, transcription, search, and enrichment make no outbound connections.

This release contains the Linux x86-64 daemon, desktop client, tray,
captions overlay, and systemd user service. It requires PipeWire and a systemd
user session. Install it through NX Hub,
then fetch the speech models and start Recall:

~/.local/bin/recalld models fetch
systemctl --user daemon-reload
systemctl --user enable --now nx-recall
~/.local/bin/recalld probe
~/.local/bin/recalld allow VRChat.exe
systemctl --user restart nx-recall

Semantic search and the Memory tab use optional local models:

~/.local/bin/recalld models fetch --semantic
~/.local/bin/recalld models fetch --graph

The OpenXR headset overlay remains experimental and has not yet been validated
against a live WiVRn session.

Version 0.13.1 keeps the existing nerdrx/nx-recall app identity, asset names,
~/.local install layout, and ~/.config/nx-recall and
~/.local/share/nx-recall paths, so NX Hub upgrades in place. Transcripts,
speaker data, configuration, and downloaded models stay outside the release
payload and uninstall manifest. There are no database schema changes in this
release.
