feat: add executionIdToNodeLocatorId call counter behind feature flag

Add dev-only instrumentation to count how many times
executionIdToNodeLocatorId is called per execution run. This
provides a baseline measurement for evaluating the impact of
caching this function's results, in a later PR.

Gated behind the feature flag
"ff:expose_executionId_to_node_locator_id_cache_counters"
(localStorage). Uses the existing getDevOverride utility which
is tree-shaken from production builds via import.meta.env.DEV.

Enable in browser console:
  localStorage.setItem(
    'ff:expose_executionId_to_node_locator_id_cache_counters',
    'true'
  )

On execution completion, logs the total call count to
console.warn. No reload needed to toggle.

**feat**: Allow measurement of caching impact, behind a flag

**impact**: None unless activated, then just some logging

There isn't one.  I don't have access to AmpCode or Unito.
