Bug Report: Import Map Resolution Issue in deno install

Version: Deno 2.1.5, 2.1.6

Description

Since Deno 2.1.5, there appears to be a breaking change in how deno install handles import maps when specified both in the configuration file and via command line flag.

Current Behavior

When using deno install with both a config file containing an importMap field and the --import-map flag, Deno attempts to read the import map from the local path specified in the config file, resulting in an error.

Error message:

error: Unable to read import map at '/Users/staytuned/.deno/bin/import_map.json'

Previous Behavior

In earlier versions, Deno would ignore the importMap field in the config file when the --import-map flag was present, showing a warning:

Warning the configuration file "file:///../deno.json" contains an entry for "importMap" that is being ignored.

Steps to Reproduce

1. Create a local deno.json with:

{
  "importMap": "./import_map.json"
}

2. Run the install command:

deno install --reload -A -f --global \
  --config ./deno.json \
  --import-map https://remote-location/import_map.json \
  https://remote-location/main.ts

Expected Behavior

The --import-map flag should take precedence over the config file's importMap field, as it did in previous versions.

Additional Context

This issue is related to #26110 where remote URLs in config files are not supported. The current behavior makes it difficult to install CLI tools from remote locations that require import maps.
