* Naming: record Developer Mode in the feature-names doc and the stage paragraph
docs/feature-names.md gains the entry for the rename: the old label, the new one, Figma's
US registration for DEV MODE (7574348) as the reason with its TSDR record, the identifiers
that keep their names, and the translations that moved from a generic "dev mode" to the
developer mode. The stage paragraph in ROADMAP.md listed the mode as Dev Mode.
* Actions palette: put each search doc comment back on its function
search_text had grown a second doc line under matches's, so the sentence about the query sat
above a function that takes none. search_text now says what it reads and matches keeps its own.
