implement require(esm) using `op_import_sync` from deno_core.
possible future changes:
- cts and mts
- replace Deno.core.evalContext to optimize esm syntax detection

This PR addresses issue #25534
**Code Changes**
- Updated malva version to the latest in cli/Cargo.toml.
- Updated LanguageOptions to match new Malva config.
- Added test case same as the issue to assure changes success.
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.
This was initially added in #25399 in order to make transitioning over
from package.json to deno.json more easy, but it causes some problems
that are shown in the issue and it also means that the output of `deno
install` would have different resolution than `npm install`. Overall, I
think it's too much complexity to be smarter about this and it's
probably best to not do it. If someone needs an aliased folder then they
should keep using a package.json
Closes #25538
Closes https://github.com/denoland/deno/issues/25321
Ended up being a larger refactoring, since we're now juggling
(potentially) two config files in the same `add`, instead of choosing
one. I don't love the shape of the code, but I think it's good enough
Some smaller side improvements:
- `deno remove` supports `jsonc`
- `deno install --dev` will be a really simple change
- if `deno remove` removes the last import/dependency in the
`imports`/`dependencies`/`devDependencies` field, it removes the field
instead of leaving an empty object
The map field has been empty for years now and we don't want the emit
file to be exposed so it allows us to iterate on making the cache
faster. Additionally, it's racy/unreliable to rely on this information.
Instead, people should emit the TS files themselves using tools like
deno_emit, typescript, esbuild, etc.

info: Deno doesn't support CommonJS modules without `.cjs` extension.
hint: Rewrite this module to ESM or change the file extension to `.cjs`.
```
This commit adds support for executing top-level `.cjs` files,
as well as import `.cjs` files from within npm packages.
This works only for `.cjs` files, the contents of sibling `package.json`
are not consulted for the `"type"` field.

Running a file like:
```
import "@std/dotenv/load";
```
Without a mapping in `imports` field of `deno.json` or `dependencies` of
`package.json`
will now error out with a hint:

This allows using npm deps of jsr deps without having to add them to the
root package.json.
Works by taking the package requirement and scanning the
`node_modules/.deno` directory for the best matching package, so it
relies on deno's node_modules structure.
Additionally to make the transition from package.json to deno.json
easier, Deno now:
1. Installs npm deps in a deno.json at the same time as installing npm
deps from a package.json.
2. Uses the alias in the import map for `node_modules/<alias>` for
better package.json compatiblity.
These now works:
```
$ deno add @std/dotenv/load
$ deno add npm:preact/hooks
```
Previously we were erroring out, because this is a "package reference"
including
a subpath.

`--allow-run` even with an allow list has essentially been
`--allow-all`... this locks it down more.
1. Resolves allow list for `--allow-run=` on startup to an absolute
path, then uses these paths when evaluating if a command can execute.
Also, adds these paths to `--deny-write`
1. Resolves the environment (cwd and env vars) before evaluating
permissions and before executing a command. Then uses this environment
to evaluate the permissions and then evaluate the command.
This PR serves as a part of #22907 .

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.

Note: this is implemented on Deploy. However, according to @magurotuna,
a thin compatibility layer might be in the works that'd prevent
breakages for PRs such as this one.

`deno bundle` now produces:

`deno bundle --help` now produces:

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.

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.

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
This commit enables the `log` feature for the `tracing` crate.
This allows us to examine additional detailed logs emitted by third party crates
that use `tracing` crate for logging by setting `RUST_LOG` env var or passing
`-L` option in command line.
Closes #25045
Fixes #24607.
This PR makes the logic that caches top level dependencies (things
present in import map) smarter, so we handle JSR dependencies without
root exports.
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.
PrismJS uses `WorkerGlobalScope` and `self` for detecting browser's Web
Worker context:
59e5a34713/prism.js (L11)
Now the detection logic above is broken when it's imported from Deno's
Web Worker context because we only hide `self` (Prism assumes when
`WorkerGlobalScope` is available, `self` is also available).
This change fixes the above by also hiding `WorkerGlobalScope` global in
Node compat mode.
closes #25008
This change improves the Node.js compatibility in managed npm resolution
mode by disabling the discovery of `node_modules` when the
main specifier is inside of `DENO_DIR`.
closes #22732
closes #24589
From upgrading `deno_lint`.
Previously if you had a node project that used a bunch of node globals
(`process.env`, etc), you would have to fix the errors by hand. This PR
includes a new lint that detects usages of node globals (`process`,
`setImmediate`, `Buffer`, etc.) and provides an autofix to import the
correct value. For instance:
```ts
// main.ts
const _foo = process.env.FOO;
```
`deno lint` gives you
```ts
error[no-node-globals]: NodeJS globals are not available in Deno
--> /home/foo.ts:1:14
|
1 | const _foo = process.env.FOO;
| ^^^^^^^
= hint: Add `import process from "node:process";`
docs: https://lint.deno.land/rules/no-node-globals
Found 1 problem (1 fixable via --fix)
Checked 1 file
```
And `deno lint --fix` adds the import for you:
```ts
// main.ts
import process from "node:process";
const _foo = process.env.FOO;
```
