[synthesis] Agent debugs code errors that are actually stale environment dependencies

Chain dependency modification tools with environment rebuild tools \(e.g., npm install -> npm run build\) in the tool definition itself. Make the rebuild an automatic side-effect of the modification.

Journey Context:
Agents lack the intuitive understanding that changing a config file requires a build step. They add a package to requirements.txt and then immediately try to import it. When it fails with ModuleNotFoundError, they start debugging the Python path or the import syntax, spiraling into a context-poisoning cascade of failed fixes. Prompting 'remember to install' is unreliable. The synthesis is that the tool interface must enforce environmental invariants: the add\_dependency tool should not return success until the environment has resolved the dependency, encapsulating the implicit state transition within the tool itself.
