Fixes playwright on linux, as reported in
https://github.com/denoland/deno/issues/16899#issuecomment-2378268454.
The issue was that we were opening the socket in nonblocking mode, which
meant that subprocesses trying to use it would get a `EWOULDBLOCK` error
(unexpectedly). The fix here is to only set nonblocking mode on our end
(which we need to use asynchronously)
Fixes #26498.
This was a sort of intentional decision originally, as I wanted to avoid
caching extra files that may not be needed. It seems like that behavior
is unintuitive, so I propose we cache all of the exports of listed jsr
packages when you run a bare `deno install`.
This commit makes sure that `deno add`, `deno install` and `deno remove`
update the lockfile if only `package.json` file is present.

1. Respects the formatting of the file (ex. keeps four space indents or
tabs).
2. Handles editing of comments.
3. Handles trailing commas.
4. Code is easier to maintain.
This PR fixes the issue where mapped specifiers in a workspace member
would never be found. Only mapped paths from the workspace root would
resolve.
This was caused by always passing the workspace root url to the import
map resolver instead of the workspace member one.

Fixes https://github.com/denoland/deno/issues/26115.
We weren't normalizing the headers to lower case, so code that attempted
to delete the `Content-Length` header (but used a different case) wasn't
actually removing the header.
partially unblocks #25470
This PR aligns the resolution of `localhost` hostname to Node.js
behavior.
In Node.js `dns.lookup("localhost", (_, addr) => console.log(addr))`
prints ipv6 address `::1`, but it prints ipv4 address `127.0.0.1` in
Deno. That difference causes some errors in the work of enabling
`createConnection` option in `http.request` (#25470). This PR fixes the
issue by aligning `dns.lookup` behavior to Node.js.
This PR also changes the following behaviors (resolving TODOs):
- `http.createServer` now listens on ipv6 address `[::]` by default on
linux/mac
- `net.createServer` now listens on ipv6 address `[::]` by default on
linux/mac
These changes are also alignments to Node.js behaviors.
`napi_call_function` should use our equiv of NAPI_PREAMBLE (`&mut Env`
instead of `*mut Env`) since it needs to set error codes based on
whether the body of the function raised a JS exception.

This came up on Discord as a question so I thought it's worth adding a
hint for this as it might be a common pitfall.

Originally I wanted to put them in package.json if there's no deno.json,
but on second thought it makes more sense to just create a deno.json

When using the `--unstable-detect-cjs` flag or adding `"unstable":
["detect-cjs"]` to a deno.json, it will make a JS file CJS if the
closest package.json contains `"type": "commonjs"` and the file is not
an ESM module (no TLA, no `import.meta`, no `import`/`export`).
