Detect when a user-defined method collides with the reserved
__lwc_component_class_internal_private_ prefix by tracking which methods
the forward transform renames and verifying the reverse transform only
restores those same methods. Throws a descriptive error on mismatch.

…thod transforms

Add 10 new tests covering forward-only output verification, combined
flags, method ordering, default/destructuring params, empty bodies,
same-name coexistence, and intermediate plugin scenarios (body mutation,
method injection, near-miss prefix matching).

Made-with: Cursor

Remove private method example added for testing; not needed in the playground.

Made-with: Cursor

Move the constant literal out of the visitor body into a module-level
METHOD_KIND constant.

… transforms

Deduplicate the repeated if-node.X-!= null property copying into a single
helper in utils.ts, used by both the forward and reverse transforms.

…ent plugins

Both transforms are now standalone Babel plugins returning PluginObj directly,
re-exported from index.ts. The forward transform is no longer bundled inside
the main LwcClassTransform Program.enter; instead it runs as a separate plugin
before the main plugin in the pipeline.

Made-with: Cursor

Add ! to the transformSync() return in each helper function so callers
can use result.code instead of result!.code everywhere.

Made-with: Cursor

Combine split expect(code).toContain() calls into single assertions that
match the full substring (e.g. 'static async #fetch(url, opts = {})').

Made-with: Cursor

Verify that private fields (#count, #name) are not affected by the
private method transform, both alone and alongside private methods.

Made-with: Cursor

Validate that private method call sites, private field references in
method bodies, and mixed field/method classes all behave correctly
through the transform pipeline without leaking prefixed names.

Made-with: Cursor

Extend the private method transform to also handle MemberExpression
nodes with PrivateName properties (e.g. this.#foo()), not just
ClassPrivateMethod definitions. This ensures the intermediate AST is
fully consistent—both definitions and call sites use the prefixed
public name—so intermediate plugins can process the code correctly.

… playground

Add enablePrivateMethods to RollupLwcOptions and forward it to the
compiler's transformSync call. Enable it in the playground rollup
config and add a private method to the counter component for testing.

Made-with: Cursor

Remove test private method from counter component and revert
playground rollup config back to default lwc() options.

Made-with: Cursor

Remove fixture test files from this branch; they now live on
a-chabot/private-methods-fixture-tests.

Made-with: Cursor

Remove 16 inline tests from private-method-transform.spec.ts that
are now covered by fixture-based tests on the fixture branch.

Made-with: Cursor

Remove 13 inline tests from private-method-transform.spec.ts that are
now redundant with fixture tests (8 already covered, 5 converted to new
fixtures). Add comments to the 10 remaining inline tests explaining why
they must stay inline (custom pipelines, forward-only, reverse-only).

Made-with: Cursor

Consolidate the individual "Kept inline" comments into a single
explanatory note at the top of the file describing why these tests
cannot be fixture tests.

Made-with: Cursor

Test that cross-class #privateName access is a parse error, and that a
spoofed mangled name definition is harmlessly round-tripped back to a
class-scoped private method.
