Currently, importing a module only for its side effect results in an
`ERR_TYPES_NOT_FOUND` error with `nodeModulesDir=manual`.

- Each workspace directory is probed for a `tsconfig.json`.
- These and any that are included by their `references` are put into a
list ordered by priority.
- A tsconfig has lower priority than its `references`.
- An earlier listed entry in `references` has higher priority than a
later one.
- A probed tsconfig in an inner directory has higher priority than an
outer one. Their `references` would be interspersed between them.
- Each tsconfig has a filter based on its `files`, `include` and
`exclude` fields. If it doesn't have `files` or `include`, it will match
any path in its containing directory not exempted by `exclude`.
- For type-checking, each root path will be allocated compiler options
based on the first tsconfig it whose filter it matches from this list.
- Only if it doesn't match any tsconfig, it will fall back to using the
nearest `deno.json`. If it's a workspace member and the root `deno.json`
has `compilerOptions`, these will be merged using the same logic from
`extends`.
Inheritance between configs strictly occurs via `extends` in a
`tsconfig.json`, and between workspace member and root `deno.json`s'
`compilerOptions`. There is no implicit inheritance between
`tsconfig.json` and `deno.json`.
The default compiler options currently applied against tsconfigs are
Deno's normal defaults, with the exception of `lib`. The default value
for `lib` is `["deno.window", "deno.unstable", "dom"]` for files in the
scope of a tsconfig with `lib` unspecified. This behaviour is depended
on by, for example, the template project created by `create-vite ->
svelte`. I expect we'll add more such exceptions over time with other
fields.
Since `rust 1.87.0` reported `undefined symbol:
ring::pbkdf2::PBKDF2_HMAC_SHA1::*` in CI and it was difficult to debug
locally, use `rust 1.86.0` in CI tests for troubleshoot the errors
This commit makes `deno check` ignore `Cannot find module` diagnostic if the
missing module specifier matches one of ambient module pattern. (For
example if there's `declare module "*.svg" { ... }` declaration in one
of d.ts files, importing of `<any>.svg` doesn't cause type error with
this change. This is necessary for passing the type checking of default
vite template.)

This adds support for using a local copy of an npm package.
```js
// deno.json
{
"patch": [
"../path/to/local_npm_package"
],
// required until Deno 2.3, but it will still be considered unstable
"unstable": ["npm-patch"]
}
```
1. Requires using a node_modules folder.
2. When using `"nodeModulesDir": "auto"`, it recreates the folder in the
node_modules directory on each run which will slightly increase startup
time.
3. When using the default with a package.json (`"nodeModulesDir":
"manual"`), updating the package requires running `deno install`. This
is to get the package into the node_modules directory of the current
workspace. This is necessary instead of linking because packages can
have multiple "copy packages" due to peer dep resolution.
Caveat: Specifying a local copy of an npm package or making changes to
its dependencies will purge npm packages from the lockfile. This might
cause npm resolution to resolve differently and it may end up not using
the local copy of the npm package. It's very difficult to only
invalidate resolution midway through the graph and then only rebuild
that part of the resolution, so this is just a first pass that can be
improved in the future. In practice, this probably won't be an issue for
most people.
Another limitation is this also requires the npm package name to exist
in the registry at the moment.
Updates to use rust 1.85. Doesn't move to the 2024 edition, as that's a
fair bit more involved.
A nice side benefit is that the new rustc version seems to lead to a
slight reduction in binary size (at least on mac):

Fixes https://github.com/denoland/deno/issues/28223
This is kind of an ugly fix, but it works, and I think is the easiest
way to handle the fact that when caching the module graph we might
encounter imports that won't actually error at runtime (for instance in
files that will be bundled).
Instead of hard erroring, we now surface module not found errors as
TypeScript diagnostics (we have yet to show the source code of the
error, but something we can improve over time).
Currently deno eagerly caches all npm packages in the workspace's npm
resolution. So, for instance, running a file `foo.ts` that imports
`npm:chalk` will also install all dependencies listed in `package.json`
and all `npm` dependencies listed in the lockfile.
This PR refactors things to give more control over when and what npm
packages are automatically cached while building the module graph.
After this PR, by default the current behavior is unchanged _except_ for
`deno install --entrypoint`, which will only cache npm packages used by
the given entrypoint. For the other subcommands, this behavior can be
enabled with `--unstable-npm-lazy-caching`
Fixes#25782.

Ensures a dynamic import in a CJS file will consider the referrer as an import for node resolution.
Also adds fixes (adds) support for `"resolution-mode"` in TypeScript.
Improving the breadth of collected data, and ensuring that the collected
data is more likely to be successfully reported.
- Use `log` crate in more places
- Hook up `log` crate to otel
- Switch to process-wide otel processors
- Handle places that use `process::exit`
Also adds a more robust testing framework, with a deterministic tracing
setting.
Refs: https://github.com/denoland/deno/issues/26852
This will respect `"type": "commonjs"` in a package.json to determine if
`.js`/`.jsx`/`.ts`/.tsx` files are CJS or ESM. If the file is found to
be ESM it will be loaded as ESM though.
* cts support
* better cjs/cts type checking
* deno compile cjs/cts support
* More efficient detect cjs (going towards stabilization)
* Determination of whether .js, .ts, .jsx, or .tsx is cjs or esm is only
done after loading
* Support `import x = require(...);`
