chore(deps): bump esbuild and tsx in /tests

[dependabot]

Bumps esbuild and tsx. These dependencies needed to be updated together.
Updates esbuild from 0.27.7 to 0.28.2

Release notes

Sourced from esbuild's releases.

v0.28.2

• Fix tree shaking bug due to TypeScript import alias (#4507)

  This release fixes a bug that could cause esbuild to incorrectly tree-shake imports that are used in a TypeScript type alias under certain circumstances. Affected code uses a TypeScript-specific import assignment and looks something like this:

  import Base from './dep.js';
  import Alias = Base.SomeType;

• Fix CSS minification bug involving & (#4497)

  This release fixes a bug where esbuild's CSS minifier incorrectly removed a & when it was unsafe to do so. Here is an example:

  /* Original code */
  .a .b {
    & .b:not(& .c) {
      color: red;
    }
  }
  /* Old output (with --minify) */
  .a .b{.b:not(& .c){color:red}}
  /* New output (with --minify) */
  .a .b{& .b:not(& .c){color:red}}

  This should match <span class="a"><span class="b"><span class="b">yes</span></span></span> but not <span class="a"><span class="b">no</span></span>. The old output incorrectly matched both.

• Avoid overwriting input files without --allow-overwrite (#4484)

  For example: esbuild input.js --outfile=input.js tells esbuild to overwrite input.js with the output of running esbuild on it. This was supposed to already be prevented by default, but it accidentally regressed in version 0.17.0 and apparently didn't have any test coverage. The error message was being printed but the input file was still being overwritten. Oops.

  This release puts the original behavior back. With this release, esbuild should now actually avoid overwriting input files unless --allow-overwrite is explicitly present. This is done by not writing out any files when a build error is encountered.

• Fix incorrect code generated when using top-level await (#4498)

  Previously esbuild could generate code containing a syntax error in complex scenarios involving top-level await used in a dependency cycle. The problem was a missing async on one or more module wrapper closures. With this release, esbuild now uses a fixed-point iteration algorithm to correctly annotate all dependencies in the cycle as needing an async module wrapper.

• Fix a minification bug with lowered logical assignment operators (#4508)

  This release fixes a bug that could cause esbuild to generate incorrect code for logical assignment operators when lowering them to an older target environment. Specifically the lowering process requires duplicating the left-hand side, but esbuild incorrectly failed to count the duplicate as a new usage when the left-hand side is an identifier. That then caused the minifier to believe that the left-hand side was only used once and could attempt to incorrectly inline an initializer into the first usage. This bug has now been fixed:

  // Original code
  function foo() {
    let x
    bar(x ||= {})

... (truncated)

Maintainer changes

This version was pushed to npm by GitHub Actions, a new releaser for tsx since your current version.

Note

Overview
Updates tests/package-lock.json so dev tooling pulled in via promptfoo uses newer esbuild (0.27.7 → 0.28.2) and tsx (4.21.0 → 4.23.12), including all platform-specific @esbuild/* optional packages.

tsx no longer depends on get-tsconfig / resolve-pkg-maps and now pins esbuild ~0.28.0. The lockfile also adds @types/json-schema and stops marking hono as optional.
