This commit improves error messages for unstable APIs:
- `--unstable-broadcast-channel`
- `--unstable-cron`
- `--unstable-http`
- `--unstable-kv`
- `--unstable-temporal`
By providing information and hints what went wrong and how the
error can be fixed. It reuses the same infra that was added in
https://github.com/denoland/deno/pull/21764.
```
$ cat exports_error.js
Object.defineProperty(exports, "__esModule", { value: true });
$ deno exports_error.js
error: Uncaught (in promise) ReferenceError: exports is not defined
Object.defineProperty(exports, "__esModule", { value: true });
^
at file:///exports_error.js:1:23
info: Deno doesn't support CommonJS modules without `.cjs` extension.
hint: Rewrite this module to ESM or change the file extension to `.cjs`.
```
`deno bundle` now produces:
```
error: ⚠️ `deno bundle` was removed in Deno 2.
See the Deno 1.x to 2.x Migration Guide for migration instructions: https://docs.deno.com/runtime/manual/advanced/migrate_deprecations
```
`deno bundle --help` now produces:
```
⚠️ `deno bundle` was removed in Deno 2.
See the Deno 1.x to 2.x Migration Guide for migration instructions: https://docs.deno.com/runtime/manual/advanced/migrate_deprecations
Usage: deno bundle [OPTIONS]
Options:
-q, --quiet Suppress diagnostic output
--unstable Enable all unstable features and APIs. Instead of using this flag, consider enabling individual unstable features

Fix task names containing a colon not being found with `deno run`. We
were only checking for a `module not found` error message, but strings
containing a colon throw a different error.
Fixes https://github.com/denoland/deno/issues/25232
- rewrite flag help
- use gray for indentation
- reorganize permission flags and split them up
- make help subcommand act like help flag
- `deno run` outputs list of tasks
- Fixes #25120
error handling for `deno run` in case of no config file being found
needs to be improved

This commit deprecates "import assertions" proposal that has been
replaced with "import attributes".
Any time an import assertion is encountered a warning will be printed
to the terminal. This warning will be printed for both local and
remote files (ie. user code and dependencies).
Import assertions support will be removed in Deno 2.
Permission flags are unified in a clearer and concise output.
Unstable flags are hidden by default with exception of the `unstable`
flag itself. the remaining unstable flags can be seen with a
`--help=unstable`.
This also cleans up to show unstable flags only for subcommands that
actually need them.
Also sorts flags alphabetically, and gorups various flags together in a
set of categories.

This commit rewrites the internal `version` module that exported
various information about the current executable. Instead of exporting
several consts, we are now exporting a single const structure that
contains all the necessary information.
This is the first step towards cleaning up how we use this information
and should allow us to use SUI to be able to patch this information
in already produced binary making it easier to cut new releases.

In preparation for https://github.com/denoland/deno/pull/25014, this
commit removes public `is_canary()` method and instead uses an enum
`ReleaseChannel` to be able to designate more "kinds" of builds.
Adds a `parallel` flag to `deno serve`. When present, we spawn multiple
workers to parallelize serving requests.
```bash
deno serve --parallel main.ts
```
Currently on linux we use `SO_REUSEPORT` and rely on the fact that the
kernel will distribute connections in a round-robin manner.
On mac and windows, we sort of emulate this by cloning the underlying
file descriptor and passing a handle to each worker. The connections
will not be guaranteed to be fairly distributed (and in practice almost
certainly won't be), but the distribution is still spread enough to
provide a significant performance increase.

This PR updates `deno run` to fallback to executing tasks when there is
no script with the specified name. If there are both script and a task
with the same name then `deno run` will prioritise executing the script.

Closes #24517
Closes #20729
Adds support for running npm package lifecycle scripts, opted into via a
new `--allow-scripts` flag.
With this PR, when running `deno cache` (or `DENO_FUTURE=1 deno
install`) you can specify the `--allow-scripts=pkg1,pkg2` flag to run
lifecycle scripts attached to the given packages.
Note at the moment this only works when `nodeModulesDir` is true (using
the local resolver).
When a package with un-run lifecycle scripts is encountered, we emit a
warning suggesting things may not work and to try running lifecycle
scripts. Additionally, if a package script implicitly requires
`node-gyp` and it's not found on the system, we emit a warning.
Extra things in this PR:
- Extracted out bits of `task.rs` into a separate module for reuse
- Added a couple fields to `process.config` in order to support
`node-gyp` (it relies on a few variables being there)
- Drive by fix to downloading new npm packages to test registry
---
TODO:
- [x] validation for allow-scripts args (make sure it looks like an npm
package)
- [x] make allow-scripts matching smarter
- [ ] figure out what issues this closes
---
Review notes:
- This adds a bunch of deps to our test registry due to using
`node-gyp`, so it's pretty noisy
Also removes permissions being passed in for node resolution. It was
completely useless because we only checked it for reading package.json
files, but Deno reading package.json files for resolution is perfectly
fine.
My guess is this is also a perf improvement because Deno is doing less
work.
https://github.com/denoland/deno/pull/23838 might accidentally disable
import assertions support because of V8 12.6 unshipping it, but we want
import assertions to be supported until Deno 2.
Construct a new module graph container for workers instead of sharing it
with the main worker.

1. Generally we should prefer to use the `log` crate.
2. I very often accidentally commit `eprintln`s.
When we should use `println` or `eprintln`, it's not too bad to be a bit
more verbose and ignore the lint rule.
By default, `deno serve` will assign port 8000 (like `Deno.serve`).
Users may choose a different port using `--port`.
`deno serve /tmp/file.ts`
`server.ts`:
```ts
export default {
fetch(req) {
return new Response("hello world!\n");
},
};
```
In preparation for upcoming changes to `deno install` in Deno 2.
If `-g` or `--global` flag is not provided a warning will be emitted:
```
⚠️ `deno install` behavior will change in Deno 2. To preserve the current behavior use `-g` or `--global` flag.
```
The same will happen for `deno uninstall` - unless `-g`/`--global` flag
is provided
a warning will be emitted.

This commit changes "deno init" subcommand to use "jsr:" specifier for
standard library "assert" module. It is unversioned, but we will change
it to `@^1` once `@std/assert` release version 1.0.
This allows us to start decoupling `deno` and `deno_std` release. The
release scripts have been updated to take that into account.
This was showing up on the flamegraph.
