writeStructAccessors only checked generated GetX/SetX names against
methods oapi-codegen had already emitted, not against other field
names on the same struct. Terraform schemas can legitimately have two
unrelated fields where one field's name is the accessor name the other
would generate, e.g. aws_instance's get_password_data (bool) and
password_data (string) become sibling fields GetPasswordData and
PasswordData. Generating GetPasswordData() for the PasswordData field
then collides with the GetPasswordData field itself, which Go rejects
outright ("field and method with the same name"), breaking the build
for provider-aws-ec2's InstanceStatusAtProvider and
SpotInstanceRequestStatusAtProvider.
Skip emitting an accessor whenever its name matches any field name on
the struct, the same way we already skip when it matches an existing
method.

- Around line 503-504: Update the accessor collision test around PasswordData
and GetPasswordData to use table-driven cases with args, want, and reason
fields, covering both getter and setter collision paths. Validate each generated
method set with cmp.Diff so regressions in either collision check are detected.
In `@internal/schemas/generator/accessors.go`:
- Around line 158-160: Update the field-name collection in addAccessors to
record anonymous fields even when field.Names is empty, deriving the embedded
type’s declared name as Go does. Preserve existing named-field handling so
accessor generation skips methods that would conflict with embedded field names.

…rive the collision test Addresses CodeRabbit review on crossplane#366: - addAccessors skipped anonymous/embedded fields entirely when collecting fieldNames, but Go promotes an embedded type's own name into the struct's namespace, so an embedded field can still collide with a generated accessor even though go/ast reports it with an empty field.Names. Add embeddedFieldName to derive the promoted name (stripping pointer indirection and package qualification) and record it alongside named fields. - Rewrite TestAddAccessorsSkipsFieldNameCollisions as table-driven cases with args/want/reason, matching this repo's test conventions, and add coverage for the setter collision path and the embedded-field case alongside the original getter collision, diffing the full generated method set with cmp.Diff rather than spot-checking individual methods.

Summary
writeStructAccessors(ininternal/schemas/generator/accessors.go) generatesGetX/SetXaccessor methods for every struct field, but only checked the generated name against methods already emitted by oapi-codegen — not against other field names on the same struct.aws_instance'sget_password_data(bool) andpassword_data(string) become sibling Go fieldsGetPasswordDataandPasswordData. GeneratingGetPasswordData()for thePasswordDatafield then collides with theGetPasswordDatafield itself — Go rejects this outright ("field and method with the same name"), which broke compilation of provider-aws-ec2's generatedInstanceStatusAtProviderandSpotInstanceRequestStatusAtProvider.Verified the underlying Go rule isn't just a style nit — a minimal repro with a field and method sharing a name fails to compile with
field and method with the same name.Test plan
