Subject: [PATCH 1/5] fix: make `boxel parse` type-check card code in npm
 installs
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Under an `npm install` of the published CLI, `boxel parse` reported no
errors while type-checking nothing: glint aborted before it started. The
parse workspace symlinked its `node_modules` at the CLI's own nested
`node_modules`, which is populated under pnpm but empty under npm's
hoisted layout — so `@glint/ember-tsc/-private/dsl` (imported by every
compiled template) and the forced `qunit-dom` type lib never resolved,
and ember-tsc exited "with errors but produced no TS diagnostics".

- Resolve the deps `node_modules` by where `@glint/ember-tsc` actually
  is (nested under pnpm, hoisted root under npm) instead of assuming the
  nested dir.
- Drop `types: ['qunit-dom']`: card code is application code, never a
  test, so it needs no ambient test-helper type lib — and forcing one
  that isn't shipped was the first thing to fail.
- Add the `@cardstack/boxel-host/tools/*` path alias and bundle
  `host/app/tools`, so current card imports of the post-rename host tools
  resolve.

Restructures tests/integration/parse.test.ts around what this fixes:
glint now runs (a deliberate type error yields a real diagnostic, not the
"no diagnostics" masking message) and host-tools imports resolve. Four
card patterns still fail to type-check in a published install and are
marked `it.fails` with the root cause documented, as tracked follow-ups:
runtime-common resolution (and the field-value mapping that depends on
its `primitive` symbol), `@tracked` beside `<template>` in a format-class
expression, and positional helper call shapes.

Subject: [PATCH 2/5] fix: keep qunit-dom types so .test.gts files type-check
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Dropping `types: ['qunit-dom']` was an over-correction. parse discovers
and type-checks every `.gts`, including the `.test.gts` files common in
workspaces, and those call `assert.dom(...)` relying on qunit-dom's
ambient `Assert` augmentation. With `types: []` they fail with "Property
'dom' does not exist on type 'Assert'".

The npm-hoisting error this was conflated with is already fixed by the
node_modules resolution change — qunit-dom is a runtime dependency and
now resolves — so restore the type lib. Add a `.test.gts` fixture that
calls assert.dom to guard the regression.

Subject: [PATCH 3/5] docs: make parse fix comments evergreen

Rewrite the comments touched by the npm-parse fix to state the current
contract rather than the path to it: drop the bug/iteration narration
(what "broke", the "old unconditional nested path"), the "post-rename"
and "moved from commands" framing, and describe the node_modules
resolution and qunit-dom/tools rationale as timeless invariants.

Subject: [PATCH 4/5] docs: drop tracker IDs from the reworded node_modules
 comment

The rewrite moved the private tracker IDs onto changed lines, so they
read as newly introduced. The comment states the same contract without
them.

Describe the tripwire as a stable invariant — expected failures while the
published CLI lacks support, with an unexpected pass as the signal to
promote them — rather than a "when a fix lands" sequence.
