Adopt TypeScript 7 stable and tune editor/lint config (#5306)

* chore: exclude claude worktrees from zed scanning and eslint

* chore: use tsgo alone as zed language server for js and ts

* chore: cover TSX in zed language settings

* chore: replace @typescript/native-preview with typescript@next, tsgo with tsc

* chore: update zed to tsgo extension's typescript-ls language server

* chore: pin typescript to latest stable 7.0 instead of nightly

* chore: alias typescript to TS6 API package for lint tooling, tsc stays TS7

TS7's typescript package drops the programmatic API until 7.1, which broke
typescript-eslint. Per the TS 7.0 announcement, alias typescript to
@typescript/typescript6 for API consumers and install TS7 as
@typescript/native, whose tsc binary drives builds.

* docs: fix stale tsgo references, annotate vscode TS7 extension, add changeset

* style: format .zed/settings.json

+- TypeScript compilation uses the native TS7 `tsc` (the standard `typescript` package). There is no per-package `typescript` devDependency — it is hoisted at the root. Note TS7 has no stable programmatic API yet; tools needing one must pin TS6.
 - **Every package touched by a change needs a changeset entry.** Add a file under [.changeset/](.changeset/) listing each modified package with an appropriate bump level (`minor` for breaking or new public API, `patch` otherwise). Dependency-only bumps are generated automatically — don't list them by hand.
