Treat as active pattern implementation in queries

[0xbrayo]

It is only implemented in aw-webui. Should be implemented both here and in the rust client.

Investigated the current implementation and here's a summary of what's needed:

Current state

The "treat as active" (always_active_pattern) feature is query-level only — it's currently implemented in aw-webui's queries.ts by applying filter_keyvals_regex + period_union to merge events matching the regex pattern into the "not-afk" set. The server's query language handles the actual filtering; the client just needs to pass the pattern.

What aw-client (Python) needs

aw_client/queries.py has DesktopQueryParams but is missing the pattern field. The fix is:

1. Add always_active_pattern: Optional[str] = None to DesktopQueryParams
2. In canonicalEvents(), when the pattern is set, emit the same queries as aw-webui:

   not_treat_as_afk = filter_keyvals_regex(events, "app", <pattern>);
   not_afk = period_union(not_afk, not_treat_as_afk);
   not_treat_as_afk = filter_keyvals_regex(events, "title", <pattern>);
   not_afk = period_union(not_afk, not_treat_as_afk);
   

There's already a PR for this: #93.

aw-client-rust

The Rust client currently has no query building infrastructure at all — it only handles bucket operations and event CRUD. Implementing this there would require first building the query DSL, which is a larger effort.

Recommendation

Focus on getting #93 reviewed and merged first. The Rust client can follow once it has query support.
