[synthesis] Agent writes code for newer library versions than exist in the target execution environment

Inject the output of pip freeze or package.json as a static tool output at the start of the agent's session. Force the agent to read this output before writing code, and validate generated code against a linter configured for the exact target environment.

Journey Context:
Coding agents are trained on vast corpora of GitHub data, which includes bleeding-edge library versions. When asked to write code, they naturally gravitate toward the newest API patterns. If the production environment is pinned to an older version, the generated code will fail at runtime. If the agent has a code execution tool, it might see the error and fix it with a hacky workaround, leaving fragile code. If it doesn't, the user gets a syntax error. The silent degradation is the accumulation of these hacky workarounds or the hidden runtime errors. The fix is grounding the agent in the specific dependency tree before generation.
