docs: typography hygiene + 1 in-body H1 removal across 6 pages

Replaced 84 typography characters (curly quotes, apostrophes, em/en
dashes, non-breaking hyphens) with ASCII equivalents per
docs/CLAUDE.md heading and content hygiene rules.

- docs/gateway/tools-invoke-http-api.md: 14 chars; removed the
  duplicate '# Tools Invoke (HTTP)' H1 (Mintlify renders title from
  frontmatter; the in-body H1 with parens produced a brittle anchor).

- docs/gateway/configuration-reference.md: 14 chars

 Gateway, with its own workspace, bootstrap files, and session store. This page
 covers that runtime contract: what the workspace must contain, which files get
 injected, and how sessions bootstrap against it.

 `BOOTSTRAP.md` is only created for a **brand new workspace** (no other bootstrap files present).

If you delete it after completing the ritual, it should not be recreated on later restarts.
