chore(edge-bundler): remove the eszip bundle format - #7177

The dev server is the only thing that ever loads `bootstrapURL` - `bundle()` declares the option and never reads it - and it has been importing `boot` from the bootstrap's `index-combined.ts`. That entry point is a four-line re-export barrel the bootstrap is retiring; `server.ts` is the real module behind it, exporting the same function as `serve` and patching globals on import just the same. Import the namespace and pick `serve ?? boot` at runtime so the generated stage 2 works against a bootstrap from either side of that change. `getURL()` keeps deciding which bootstrap we get, so the two can be rolled out in any order and nothing has to be pinned here.
Edge Functions no longer run on Deno Deploy. Nimble consumes the tarball format, so the eszip bundle is dead weight: every build spent time producing an artifact nothing reads. Tarball generation stops being conditional, which retires `edge_bundler_generate_tarball` and its dry-run counterpart along with the comparison logging they existed to drive. Layers no longer need to be declared as externals, since that only mattered to the eszip loader. Two user-visible consequences, both from Deno now resolving modules natively instead of through the eszip loader: `npm:` specifiers bundle and run rather than failing with an "experimental feature" error, and parse failures surface Deno's own message instead of eszip's.

The file was left formatted to prettier's width when the eszip tests were removed, which fails the `formatting` CI job. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>
Now that Deno reports parse failures itself rather than eszip doing it, the assertions capture Deno's own diagnostic - and that diagnostic is not stable across `DENO_VERSION_RANGE` (`^2.4.2`). Measured against the fixture, the same file produces three different messages: 2.4.2 says "Unexpected eof", 2.5-2.7 say "Expression expected", and 2.8+ reformat it as a `SyntaxError` with a line gutter. Snapshots recorded on 2.9.x therefore failed the oldest-supported leg and the `test-build` jobs, which pin 2.5.6. Assert only what we own - the command handed to Deno - and match Deno's wording loosely. The shared normalizer collapses the diagnostic to a marker, limited to parse failures so that Deno's other bundling errors, which are stable, keep being snapshotted in full. Also normalize the separator after the temp directory, which left the Windows leg comparing `TMP_DIR\deno.json` against `TMP_DIR/deno.json`.

Tarball generation is no longer gated behind a feature flag, so `bundlingTiming` is always populated and `buildbot.build.edge_functions.bundling_ms` is always emitted. The metric is intended; only the snapshot was missed. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>

Conflicts were both in eszip-only test code that main had reformatted or re-pathed underneath the removal: - `test/util.ts`: keep the deletion of `inspectESZIPFunction`. Main only stripped trailing whitespace inside it. Restore the `node:fs` import, though: the removal dropped it along with `runESZIP`, but main added a new `fs.cp` call in `useFixture`. - `node/bundler.test.ts`: keep the branch's assertion. Main's new `packageDir` normalisation existed to scrub the eszip vendor path out of the snapshot, and the tarball path never puts a package path in the message. Its `dirname`/`fileURLToPath` imports go with it.

Assert that every emitted bundle uses tar.
Line 36 passes when a manifest contains one tar bundle and one obsolete bundle format. The tar-only contract requires rejection of every non-tar bundle. Assert that the list is non-empty, then use every().
Proposed fix
const assertBundlesExist = (t, manifest) => {
- t.true(manifest.bundles.some(({ format }) => format === 'tar'))
+ t.true(manifest.bundles.length > 0)
+ t.true(manifest.bundles.every(({ format }) => format === 'tar'))

Measure both tarball stages.
Line 246 records the duration before finalizeTarballBundle() writes the in-bundle manifest and creates the archive. bundling_timing.tarball_ms therefore under-reports tarball generation time.
Accumulate the preparation duration and the finalization duration before writing the manifest.

Update the linked edge-bundling documentation.
netlify/blueprints/services/netlify-server.md still describes edge-function bundling as eszip. Update it to describe tarball bundling. The linked-repository scan found no code consumer that requires a compatibility change.

chore/edge-bundler-retire-index-combined, which is not yet merged. Retarget tomainonce that lands.What went
node/formats/eszip.ts,deno/bundle.ts,deno/lib/(stage 2 builder, loader, consts, and its Deno test),shared/stage2.tsdeno/vendor/tree - the vendored eszip WASM module plus the std/retry/wasmbuild modules only it pulled in.deno/config.ts(in-source config extraction) is all that remains underdeno/.test:*:denoscripts (no Deno tests left to run)Collapsed to a single format
edge_bundler_generate_tarballandedge_bundler_dry_run_generate_tarballare gone from both edge-bundler andpackages/build, along with the dry-run comparison logging they existed to drive. Buildbot still passing the flag is a harmless no-op.BundleFormatis now justTARBALL, and the manifest schema accepts onlyformat: 'tar'.Behaviour changes worth a look
BundleError(so the team is not paged for user mistakes), now withcustomErrorInfo.location.formatoftar. The tarball path did not wrap its errors before, because eszip was the one that threw first.npm:specifiers now work. The "Support for npm modules in edge functions is an experimental feature" error was an eszip limitation - Deno vendors them natively. The test that asserted the error now asserts the function bundles and runs.The module's source code could not be parsedto Deno's ownerror: SyntaxError: .... The stderr-substitution inbundle_error.tsthat keyed off the old string went with it.Testing
