chore(spec): regenerate api-surface + authorable-surface after merging main

The merge driver (`merge=os-regen`, AGENTS.md §11) deferred both artifacts
rather than text-merging them, and `pre-commit` collects that debt. Regenerated
from the MERGED source, so the union includes #5721's ActionSession entries
alongside this branch's $icontains / FILTER_TEXT additions.

`authorable-surface.base.json` is deliberately NOT bumped: it is the deletion
gate's anchor, main only moves it when a key is REMOVED, and this branch only
adds. `check:authorable-surface` confirms it — 'trails the merge base by 5
key(s) — expected right after a surface change lands'.
