docs(changelog): add vscode [1.1.0] section (release guard requires both changelogs)

The release workflow's guard asserts a dated ## [VERSION] section in BOTH
CHANGELOG.md and packages/vscode/CHANGELOG.md; the v1.1.0 tag failed fast there
because the vscode changelog was missing the section. No packages were published.

 # Loom VS Code Extension — Changelog
 
+## [1.1.0] - 2026-06-08
+
+### Added
+- **AI Reply on `refs/` chats.** Chats under `refs/` now show the **AI Reply** action,
+  same as thread and weave chats (previously only `chat`-context chats had it).
+
+### Changed
+- **Requirements-aware plan creation.** *Promote to Plan* now reads the thread's `req.md`
+  and authors the `Satisfies` column as it creates the plan, so newly created plans carry
+  requirement citations — previously only *Refine Plan* backfilled them.
+- **No double type-suffix.** Creating an idea from a title containing the word "idea" no
+  longer yields a `…-idea-idea.md` thread/file.
+
+### Notes
+- Lockstep 1.1.0 bump with the CLI and the rest of the monorepo.
