Removes the TSC snapshot to unblock the V8 upgrade (which enables shared
RO heap, and is incompatible with multiple snapshots).
this compresses the sources and declaration files as well, which leads
to a roughly 4.2MB reduction in binary size.
this currently adds about 80ms to deno check times, but code cache isn't
wired up for the extension code (namely `00_typescript.js`) yet

This commit removes the docs URL for diagnostics coming
from JS plugins. Before, we mistakenly printed
URLs pointing to `docs.deno.com`, even though they did not
exist.
An ability to actually specify a custom URL for plugin rules,
will be added in a follow up PR.
This PR fixes deviations in our AST format compared to TSEStree. They
are mostly a leftover for when I first started working on it and based
it off of babel instead.
One of the key changes why the changeset is a bit bigger is that
TSEStree uses `undefined` instead of `null` as the empty value for type
nodes. This is likely influenced by `tsc` which use `undefined`
everywhere. The rest of the nodes use `null` though. It's a little
weird, but for now it might be better to align.

https://nodejs.org/api/sqlite.html#databaseapplychangesetchangeset-options
```js
const sourceDb = new DatabaseSync(':memory:');
const targetDb = new DatabaseSync(':memory:');
sourceDb.exec('CREATE TABLE data(key INTEGER PRIMARY KEY, value TEXT)');
targetDb.exec('CREATE TABLE data(key INTEGER PRIMARY KEY, value TEXT)');
const session = sourceDb.createSession();
const insert = sourceDb.prepare('INSERT INTO data (key, value) VALUES (?, ?)');
insert.run(1, 'hello');
insert.run(2, 'world');
const changeset = session.changeset();
targetDb.applyChangeset(changeset);
// Now that the changeset has been applied, targetDb contains the same data as sourceDb.

This commit adds an unstable lint plugin API.
Plugins are specified in the `deno.json` file under
`lint.plugins` option like so:
```
{
"lint": {
"plugins": [
"./plugins/my-plugin.ts",
"jsr:@deno/lint-plugin1",
"npm:@deno/lint-plugin2"
]
}
}
```
The API is considered unstable and might be subject
to changes in the future.
Plugin API was modelled after ESLint API for the
most part, but there are no guarantees for compatibility.
The AST format exposed to plugins is closely modelled
after the AST that `typescript-eslint` uses.
Lint plugins use the visitor pattern and can add
diagnostics like so:
```
export default {
name: "lint-plugin",
rules: {
"plugin-rule": {
create(context) {
return {
Identifier(node) {
if (node.name === "a") {
context.report({
node,
message: "should be b",
fix(fixer) {
return fixer.replaceText(node, "_b");
},
});
}
},
};
},
},
},
} satisfies Deno.lint.Plugin;
```
Besides reporting errors (diagnostics) plugins can provide
automatic fixes that use text replacement to apply changes.

This PR adds the `--permit-no-files` cli options to the `bench`
subcommand. This will cause `deno bench --permit-no-files` to not return
an error when no bench files where found.
Implements the `readOnly` option for `DatabaseSync`.
Permissions:
`--allow-read=test.db --allow-write=test.db` => all works
`--allow-read=test.db` => only `readOnly` dbs work, cannot create new db
Shows directory import and missing extension suggestions in error
messages similar but not exactly to node.
Closes #26802

This PR adds support for passing wildcard tasks. All matched tasks are
sorted in case they have dependencies. Tasks already in the dependency
tree will be pruned so that every task only runs once.
```json
{
"tasks": {
"foo-1": "echo 'foo-1'",
"foo-2": "echo 'foo-2'"
}
}
```
```sh
$ deno task "foo-*"
Task foo-1 echo 'foo-1'
foo-1
Task foo-2 echo 'foo-2'
foo-2
```
The changes in the PR look a little bigger than they really are due to
formatting. For the most part, I've only needed to hoist up the task
matching logic.

This makes it so imports of ambient modules (e.g. `$app/environment` in
svelte, any virtual module in vite, or other module provided by a
bundler) don't error in the LSP.
The way this works is that when we request diagnostics from TSC, we also
respond with the list of ambient modules. Then, in the diagnostics code,
we save diagnostics (produced by deno) that may be invalidated as an
ambient module and wait to publish the diagnostics until we've received
the ambient modules from TSC.
The actual ambient modules you get from TSC can contain globs, e.g.
`*.css`. So when we get new ambient modules, we compile them all into a
regex and check erroring imports against that regex. Ambient modules
should change rarely, so in most cases we should be using a pre-compiled
regex, which executes in linear time (wrt the specifier length).
TODO:
- Ideally we should only publish once, right now we publish with the
filtered specifiers and then the TSC ones
- deno check (#27633)
