fix: validate reset+price mutual exclusivity, remove description field

[autumnbillinginternalapp]

Two atmn fixes (flagged by Ayush):

1. Validate reset + price conflict
A planFeature with both reset (free allocation) and price with amount/tiers (paid) should error — these are conflicting billing models. Added validation in push/validate.ts.

Example that now errors:

planFeature({
  feature_id: credits.id,
  included: 500_000,
  reset: { interval: "month" },
  price: { amount: 217, billing_method: "prepaid" },
})

2. Remove description field
Removed description from Plan model, builder, all transforms (apiToSdk, sdkToCode, sdkToApi), typegen config, and constants.

Files changed: 9 files across validate, models, builders, transforms, typegen, constants, and tests.

Summary by cubic

Enforces a validation that a planFeature cannot have both reset and price, and removes the Plan.description field across the codebase. This prevents conflicting billing models and simplifies the plan schema.

• Bug Fixes

  • Block reset + price (amount or tiers) on the same planFeature with a clear error.

• Migration

  • Remove description from all plan configs and usages; the field is no longer supported.

^{Written for commit f11a389. Summary will update on new commits.}

Greptile Summary

Two fixes to the plan configuration system: validation for conflicting billing models and removal of unused description field.

Key Changes:

• Bug fixes: Added validation to prevent planFeature from having both reset (free allocation) and price with amount/tiers (paid billing), which are conflicting billing models
• API changes: Removed description field from Plan model across all layers (models, builders, transforms, typegen, tests)

Confidence Score: 2/5

• This PR has a critical bug that will cause runtime failures in the push command
• The validation logic addition is correct, but atmn/src/commands/push/push.ts still references plan.description which no longer exists on the Plan type. This will cause runtime errors when comparing/normalizing plans. The file has @ts-nocheck which prevented TypeScript from catching this.
• Pay close attention to atmn/src/commands/push/push.ts - it contains a reference to the removed description field that must be fixed
