Track Albert Phase-1 launcher bridge for sourceos-shell rollout

[mdheller]

Summary

Track the temporary Albert-based launcher bridge needed during the sourceos-shell rollout.

This issue exists here because the upstream/forked SociOS-Linux/albert repository has issues disabled, but the bridge work is still part of the Linux realization track for the shell.

Goal

Route launcher queries by scope without redundant file search:

• apps -> launcher / desktop entries
• files -> Linux-native file search only
• web -> browser/web agent

Required invariant

For files queries, Albert must not perform a second file-search pass in parallel with the Linux-native provider.

Scope

• patch or plugin work in SociOS-Linux/albert
• Linux-native file-search selection (tracker3/fd/locate)
• logging proving a single provider handled each query
• automated acceptance proving files -> Linux provider only

Acceptance criteria

• routing paths exist for apps, files, and web
• files queries invoke only the Linux-native provider
• automated test proves no redundant search
• documentation points to the shell rollout and clarifies this is temporary bridge work
