Superseded by #29, which adopts the same TypeScript 6.0.3 with the full test triad run against it: tsc --noEmit exit 0, 8/8 stack tests via ts-node, cdk synth 9 stacks, plus 3711 unit/regression tests and make ci green.Also pinned as ~6.0.3 rather than a caret range, so the next major does not drift in unattended — TS 7 breaks all 8 stack tests (see #27 for the ts.sys/ts-node evidence).

…29)

Dependabot opened TypeScript 6.0.3 (#28) right after the 7.0 investigation. Tested the
same way, and it came out differently:

    6.0.3   tsc --noEmit exit 0 · 8/8 stack tests · cdk synth 9 stacks   -> ADOPTED
    7.0.2   tsc --noEmit exit 0, but ALL 8 stack tests die at startup:
                TypeError: Cannot read properties of undefined (reading 'fileExists')

`ts-node` works with TS 6 and not with TS 7, which is the native rewrite that no longer
exposes the `ts.sys` JS surface ts-node reads its tsconfig through. So the `>= 7` ignore
added in #27 is drawn at the measured break point rather than at "no major upgrades", and
this is the upgrade it was always going to allow through.

Worth recording: the implicit-`@types` removal — the cause of the 7 x TS2591 "Cannot find
name 'process'" errors seen during the 7.0 test — actually landed in **6.0**, not 7.
Verified by removing `types: ["node"]` under 6.0.3 and watching them come back. So the
one-line tsconfig fix shipped in #27 is precisely what unblocked this upgrade. It was
correct on its own terms before either upgrade was attempted, which is the useful shape:
making an implicit dependency explicit paid off one major earlier than expected.

Also documented in this branch, with evidence, a HIGH Dependabot alert that CANNOT be
fixed right now:

  brace-expansion 5.0.8 (needs 5.0.9) at
  node_modules/aws-cdk-lib/node_modules/brace-expansion, inBundle=true

`aws-cdk-lib@2.263.0` is the latest published version and it bundles the vulnerable copy.
Both remediation routes were tested and neither works: `npm audit fix` reports
`fixAvailable: true`, runs, and leaves the lockfile byte-identical; an
`overrides: {"brace-expansion": "^5.0.9"}` also leaves it at 5.0.8, because overrides
cannot reach inside a third-party bundled tarball. This is the same shape as the earlier
bundled-CVE work. It clears when upstream publishes a cdk-lib that bundles 5.0.9 — there
is no action available to this repository, and claiming otherwise would be the
"fixAvailable" lie repeated.

Tested: 3711 passed / 6 skipped (unit + regression); IaC E2E under TS 6 — tsc exit 0, 8/8
stack tests, cdk synth 9 stacks; ruff clean; make ci green.
