function-name filter: incremental + highlight + clear

- Incremental client-side filter over the cached function list (no per-keystroke
  server round-trips): narrows + highlights the matched substring in each name
  as you type, debounced ~80ms. Substring or glob (*/?), smartcase.
- Clear the filter: Esc in the filter box, OR Esc on the focused list, OR empty
  Enter. Status shows 'filter <q>: N/total'.
- streaming pauses while a filter is active; re-applied over the full set once
  load completes. Row selection resolves the name from the index (cells can now
  be styled Text).
- FunctionIndex.all_loaded(); pilot suite 27/27.
