• parse most object fields (feat(sidekick/disco): parse most object fields #2318) Parse most fields of object in a discovery doc. Fields with an inline

• Add the ability to insert text after the package title (feat: Add the ability to insert text after the package title #2323) The current use case for this is to advise users of equivalent Firebase
  packages. For example:

readme-after-title-text = """> [!TIP]
> Flutter applications should use [Firebase AI Logic](https://firebase.google.com/products/firebase-ai-logic).
>
> The Generate Language API is meant for Dart desktop and cloud applications.
> Firebase AI Logic provides client-side access to both the Gemini Developer
> API and Vertex AI. """

Which results in a README.md that looks like:

Bug Fixes

• read version from version.txt file (fix(librarian): read version from version.txt file #2347) Fixes librarian: version reports 0.0.0 #2348

Moves version.txt to the internal/cli package so it can be read by the
embed package as a variable.
When constructing the synthetic version number, use this release version
as the base. (014b5f4)

• race condition in createWorkRoot() (fix(config): race condition in createWorkRoot() #2338) Creating a temporary directory based on a timestamp is inherently racy.
  Use the standard functions to create temporary directories, and relax
  the tests to check for what matters. (46428ca)

• parse github remote from local directory (fix: parse github remote from local directory #2328) Fixes librarian tag-and-release can not use local repository #2327 (1c71bd9)
