Remove `--allow-hrtime` and `--deny-hrtime`. We are doing this because
it is already possible to get access to high resolution timers through
workers and SharedArrayBuffer.

`deno bundle` now produces:
```
error: ⚠️ `deno bundle` was removed in Deno 2.

```
`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
To view the list of individual unstable feature flags, run this command again with --help=unstable
```
Before:
```
$ deno upgrade v1.xx
error: Invalid version passed
```
After:
```
$ deno upgrade v1.xx
error: Invalid version passed (v1.xx)
Example usage:
deno upgrade | deno upgrade 1.46 | deno upgrade canary
```
Also updates help text to use "shorthand version" without flags, but a
positional arg.
This commit effectively turns Deno into Deno 2.0.
This is done by forcing `DENO_FUTURE=1` env var, that was available in
the past few months to try Deno 2 changes.
This commit contains several breaking changes scheduled for Deno 2:
- all deprecated JavaScript APIs are not available any more, mostly
`Deno.*` APIs
- `window` global is removed
- FFI, WebGPU and FS APIs are now stable and don't require
`--unstable-*` flags
- import assertions are no longer supported
- "bring your own node modules" is enabled by default
This is the first commit in a series that are scheduled before the Deno
2 release.
Follow up work is tracked in
https://github.com/denoland/deno/issues/25241.

This is blocking https://github.com/denoland/deno/pull/25213.
Turns out a bunch of FS APIs are completely broken because they
use RIDs (resource IDs) instead of FDs (file descriptors).
Stores normalized version constraints in the lockfile, which will
improve reproducibility and will fix a bug with duplicate specifiers
ending up in the lockfile. Also, gets rid of some duplicate data in the
specifiers area of the lockfile.
This commit remove `--lock-write` that was deprecated in v1.45 release.
Closes https://github.com/denoland/deno/issues/24167.

- Add missing exports to `node:cluster`
- Fix default export not being an instance of `EventEmitter`
- Fix aliasing of properties
- Fix `disconnected` -> `disconnect` export naming
This makes `log4js` work in Deno. `karma` starts too, but somehow the
server isn't responding. That looks like a different issue.
Fixes https://github.com/denoland/deno/issues/24858
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.

MacOS tends to not distribute evenly, so just don't assert that requests
were served by > 1 worker on mac.
Also added a check that all workers start, so we at least check that on
macos.
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 commit adds capability to format HTML, Svelte, Vue, Astro and Angular
files.
"--unstable-html" is required to format HTML files, and "--unstable-component"
flag is needed to format other formats. These can also be specified in the config
file.

This commit adds another test suite that runs all Deno unit tests
with `DENO_FUTURE=1` flag to ensure all APIs are working as
expected, once Deno 2 is released.

For some reason we didn't register the `node:inspector` module, which
lead to a panic when trying to import it. This PR registers it.

This commit stabilizes HMR functionality and renames
`--unstable-hmr` to `--watch-hmr`. The `--unstable-hmr`
flag is still working, but hidden from the help output.
It will be removed in Deno 2.
Once https://github.com/denoland/deno/pull/24958 lands
we should improve grouping of `--watch` and `--watch-hmr`
flags.
