- Updated all directly defined dependencies to the latest React 19 Beta
- `package.json`: used `resolutions` to force React 19 for `react-is` transitive dependency
- `package.json`: postinstall script to patch fbt for the React 19 element Symbol
- Match on the message in Snap to exclude a React 19 warning that `act` should be imported from `react` instead (from inside `@testing-library/react`)
- Some updated snapshots, I think due to now recovering behavior of `useMemoCache`, please review.
In a next step, we can do the following. I excluded it since it from here as it made the PR unreviewable on GitHub.
- Snapshots now use `react/compiler-runtime` as in prod, so the different default in Snap is no longer needed.
To make a first time setup of the compiler truly config-less, default to
not compiling node_modules unless a user provided `sources` (advanced
option) is provided

This uses the compiler runtime from `react/compiler-runtime` by default unless `compilerRuntime` is specifified in the Babel options which then imports the runtime from there. The `useMemoCache` hook is now named `c` in accordance with https://github.com/facebook/react/commit/4508873393058e86bed308b56e49ec883ece59d1
Unfortunately, I couldn't figure out how to import `react@beta` which already has that import as various react verstions were conflicting. If someone can figure this out it'd be fantastic. As a result, I had to update the default for the test runner to default the `compilerRuntime` option to `react` to preserve the previous behavior to import from `react`. Once upgraded to React 19, we should be able to remove that override.
Treat MethodCalls similar to general CallExpressions and mark them
as escaping in PruneNonEscapingScopes pass.

Add a configurable list of known incompatible libraries.
Check all package.jsons for any uses of known incompatible libraries and
warn if found.

As discussed earlier, let's disable this validation pass by default for
oss since it still has many false positives

This was probably a leftover from a previous time, but since this error
message throws when the dependency list is not an array literal, and not
just when its a rest spread, this PR updates the message to match.

It's not useful to output count of all failures,
as it's not actionable for the developer.
We'll still capture all failures in case we want
to add a rage option to this script.

Run the compiler on the globbed soruces.
The logger is used to capture the success and
failure compilation cases at the component level.
(If we were to compile the entire file directly,
we wouldn't get this granularity)
For now, we just log the number of success and
failures. In the future, we can provide a better
report building on this.

Exporting the hermes parser breaks the playground
as the hermes parser can not work in the browser.
No one is using this directly anyway -- snap and
others bundle hermes parser on their own, so,
let's remove it.

This package will be used to check for violations
of the rules of react and other heuristics to
determine the health of a codebase.
The health of a codebase gives an expectation of
how easy it will be onboard on to the compiler.
