Anonymous public-share AI assistant:
- Add a workspace setting `publicShareAssistantRoleId` so an admin can pick which
agent role (identity/persona) the anonymous assistant adopts. The role's
instructions REPLACE the built-in persona while the immutable safety framework
is still always appended; the role's optional model override takes precedence
over the cheap publicShareChatModel. Resolved server-authoritatively
(workspace-scoped, soft-delete aware; disabled/missing roles fall back to the
built-in persona, so the tool scope remains the real security boundary).
- Plumb the field through the update DTO, ai-settings service, the workspace.repo
ALLOWED whitelist, resolve()/getMasked(), stream-time role resolution and the
prompt/model, plus the settings UI: a new "Assistant identity" Select listing
enabled roles (and surfacing a saved-but-disabled role explicitly).
Public-share branding / floating icon:
- Fix the AI assistant FAB overlapping the "Powered by ..." button (both were
Affixed bottom-right): stack the FAB above the bottom-right branding.
- Rename "Powered by Docmost" -> "Powered by Gitmost" and point the link at the
gitmost repo.
Tests: extend public-share-chat.spec (role persona replacement still appends the
safety framework, resolveShareRole edge cases, model-override precedence).
