Part of #364 (item 4: env keys and values interpolated into kernel source without escaping).

Environment keys and values were interpolated directly into kernel source. Quotes and newlines could make that source invalid, and backslashes could silently change values. Cleanup used the same interpolation when restoring global values or deleting execution-specific keys.

Use Python repr, JSON string literals for JavaScript/TypeScript and Java, quoted strings with named arguments supplied through do.call for R, and shell quoting for Bash assignments and deletion. This keeps the existing environment lifecycle while preserving literal keys and values.

Add parameterized kernel regressions for quotes, newlines, backslashes, and cleanup. Local dependency-free checks of the production methods passed under Python, Node, and Bash, including global-value restoration and shell metacharacters. The E2B integration suite and R/Java runtimes were not available locally.

This addresses escaping only. History retention, logging, and cancellation cleanup from #364 remain outside this change, so the issue should remain open.

AI disclosure: This change and its tests were generated with assistance from OpenAI Codex.
