This is mostly to align with webmachinelearning/writing-assistance-apis#43:

  • Use the proposed QuotaExceededError when appropriate, instead of a "QuotaExceededError" DOMException.
  • Rename maxTokens/tokensSoFar to inputQuota/inputUsage.
  • Rename countPromptTokens() to measureInputUsage().
  • Remove tokensLeft.
  • Rename "contextoverflow" to "quotaoverflow".

This is mostly to align with webmachinelearning/writing-assistance-apis#31:

* Use TooManyTokensError when appropriate, instead of a "QuotaExceededError" DOMException.
* Rename tokensLeft/tokensSoFar to tokensAvailable/tokenCount.
* Rename countPromptTokens() to countTokens().
* Remove maxTokens.
* Rename "contextoverflow" to "overflow", since the vocabulary "context" is not used elsewhere in the API and there's only one relevant type of overflow for the session.
