Stratos v5.3.0

Features

• The performance page now measures what Stratos actually controls: the
  headline splits initial-load from since-load activity, a document-fetch
  phase row covers the gap before Angular boots, and a Stratos-clock
  column (with a waterfall toggle) times requests from the console's own
  start instead of the browser's.
• The side-nav "Show all menu items" checkbox is now a debug tool, gated
  behind the theme's debug.showAllMenuItemsToggle company-config flag
  and hidden by default; stale browser state is ignored while the gate
  is off.

Bug Fixes

• Completions and go-to-definition returned to the editor: monaco
  0.56's per-feature registry omits the suggest controller and the
  go-to commands (upstream's full build imports them directly), so the
  curated subset lost Ctrl+Space and F12. Found by live-driving the
  deployed editor; the contribs are now imported directly.
• Monaco's static widget styles finally reach the page: the builder
  bundles the CSS monaco imports from JS into chunk .css files, but
  nothing attaches those for a plain dynamic import() — since the ESM
  switch the editor has rendered on runtime-injected styles and
  browser defaults (visible with monaco 0.56 as a naked IME textarea
  inside the editor and a chromeless find widget). The subset's CSS is
  now built as a stable non-injected "monaco" styles bundle that the
  loader links when the editor loads.
• The Monaco editor prefetch waits for the window load event, so warming
  the editor bundle no longer distorts the initial-load milestone on the
  performance page.
• 304 revalidations are counted as cache validations on the performance
  page instead of full transfers.

Maintainability

• The Monaco editor now ships as a curated feature-and-language subset
  (core editor, json language service, yaml tokenizer) instead of the
  full build with ~80 bundled languages: the editor-open payload drops
  from 868KB to 785KB gzipped and the built frontend loses 800KB of
  never-used language modules. The subset also prefetches once the
  browser goes idle after bootstrap, so the first editor surface opens
  without paying the chunk fetch at click time. A bundle budget now
  fails the build if the chunk regresses toward the full build.

Chores

• Removed the unused background-grid/background-image CSS that the
  Docusaurus template carried in; one rule used Sass-style &--
  nesting that plain CSS can't parse, tripping an optimizer warning
  on every website build.
• monaco-editor updated 0.52.2 to 0.56.0 (supersedes the dependabot
  bump): the new exports map breaks every legacy deep-import path, so
  the curated feature subset now uses the 0.53+ feature registry, the
  json/yaml language registers, and the new worker entry points. The
  one incompatible dependency import (monaco-worker-manager, used by
  monaco-yaml's worker) is fixed with a one-line dependency patch.
• eslint updated 9.39.5 to 10.8.1 (supersedes the dependabot bump):
  eslint 10 stops bundling @eslint/js, so it becomes a direct dev
  dependency, and its newly-recommended rules surfaced 15 real
  findings — caught errors are now attached as cause when rethrown
  as user-facing messages, and two dead assignments are gone.
• New deploy guide for keeping SQLite state across Cloud Foundry
  restarts: continuous Litestream replication and user-provided-service
  snapshots, with the two hard preconditions both lanes share — a stable
  ENCRYPTION_KEY and SQLITE_KEEP_DB=true (without the latter,
  jetstream deletes the database file at startup and a Litestream
  replica is then overwritten with the emptied database).
• Dependency updates: the angular group with 18 updates; the
  angular-devkit group; @analogjs/vite-plugin-angular from 2.6.4 to
  2.7.0; mktemp from 2.0.1 to 2.0.3. (The monaco-editor 0.56 and
  ESLint 10 moves are covered by their own entries above.)
