build(deps): bump esbuild and tsx

[dependabot]

Bumps esbuild to 0.27.1 and updates ancestor dependency tsx. These dependencies need to be updated together.

Updates esbuild from 0.18.20 to 0.27.1

Release notes

Sourced from esbuild's releases.

v0.27.1

• Fix bundler bug with var nested inside if (#4348)

  This release fixes a bug with the bundler that happens when importing an ES module using require (which causes it to be wrapped) and there's a top-level var inside an if statement without being wrapped in a { ... } block (and a few other conditions). The bundling transform needed to hoist these var declarations outside of the lazy ES module wrapper for correctness. See the issue for details.

• Fix minifier bug with for inside try inside label (#4351)

  This fixes an old regression from version v0.21.4. Some code was introduced to move the label inside the try statement to address a problem with transforming labeled for await loops to avoid the await (the transformation involves converting the for await loop into a for loop and wrapping it in a try statement). However, it introduces problems for cross-compiled JVM code that uses all three of these features heavily. This release restricts this transform to only apply to for loops that esbuild itself generates internally as part of the for await transform. Here is an example of some affected code:

  // Original code
  d: {
    e: {
      try {
        while (1) { break d }
      } catch { break e; }
    }
  }
  // Old output (with --minify)
  a:try{e:for(;;)break a}catch{break e}
  // New output (with --minify)
  a:e:try{for(;;)break a}catch{break e}

• Inline IIFEs containing a single expression (#4354)

  Previously inlining of IIFEs (immediately-invoked function expressions) only worked if the body contained a single return statement. Now it should also work if the body contains a single expression statement instead:

  // Original code
  const foo = () => {
    const cb = () => {
      console.log(x())
    }
    return cb()
  }
  // Old output (with --minify)
  const foo=()=>(()=>{console.log(x())})();
  // New output (with --minify)
  const foo=()=>{console.log(x())};

• The minifier now strips empty finally clauses (#4353)

  This improvement means that finally clauses containing dead code can potentially cause the associated try statement to be removed from the output entirely in minified builds:

• Fix TypeScript-specific class transform edge case (#3559)

  The previous release introduced an optimization that avoided transforming super() in the class constructor for TypeScript code compiled with useDefineForClassFields set to false if all class instance fields have no initializers. The rationale was that in this case, all class instance fields are omitted in the output so no changes to the constructor are needed. However, if all of this is the case and there are #private instance fields with initializers, those private instance field initializers were still being moved into the constructor. This was problematic because they were being inserted before the call to super() (since super() is now no longer transformed in that case). This release introduces an additional optimization that avoids moving the private instance field initializers into the constructor in this edge case, which generates smaller code, matches the TypeScript compiler's output more closely, and avoids this bug:

  // Original code
  class Foo extends Bar {
    #private = 1;
    public: any;
    constructor() {
      super();
    }
  }
  // Old output (with esbuild v0.19.9)
  class Foo extends Bar {
  constructor() {
  super();
  this.#private = 1;
  }
  #private;
  }
  // Old output (with esbuild v0.19.10)
  class Foo extends Bar {
  constructor() {
  this.#private = 1;
  super();
  }
  #private;
  }
  // New output
  class Foo extends Bar {
  #private = 1;
  constructor() {
  super();
  }
  }

• Minifier: allow reording a primitive past a side-effect (#3568)

  The minifier previously allowed reordering a side-effect past a primitive, but didn't handle the case of reordering a primitive past a side-effect. This additional case is now handled:
