fix(coding-agent): add missing strip-ansi dependency (#1738)

strip-ansi is imported in bash-executor.ts and two interactive mode
components but is not declared in package.json dependencies. This
causes ERR_MODULE_NOT_FOUND at runtime in strict package managers
like pnpm that do not hoist undeclared dependencies.
