- test_insights.TestGatewayFormatting.test_gateway_format_hides_cost:
  PR NousResearch#11477 hid cost/cache from format_gateway but only updated the
  terminal-formatting test. The gateway test was renamed (``hides_cost``)
  but its assertions still required ``$`` and ``Est. cost`` to be present.
  Flip them to match the new behavior.

- test_config.TestCustomProviderCompatibility: PR NousResearch#9332 re-ordered the
  provider URL-field priority to ``base_url > url > api`` (was api first).
  Rename to ``_prefers_base_url_then_url_then_api`` and flip the expected
  URL.

- test_browser_camofox_state.test_config_version_matches_current_schema:
  ``DEFAULT_CONFIG["_config_version"]`` was bumped 20 → 21 (as the test's
  own comment anticipates). Bump the expected value.

- test_interrupt_propagation._make_bare_agent: bare agents constructed via
  ``__new__`` were missing attrs now read by ``_compute_stale_timeout`` →
  ``_interruptible_api_call``. Add ``provider``, ``model``, ``_base_url``,
  ``_base_url_lower``.

…ousResearch#11477)

The cache-read, cache-write, and total estimated-cost values shown in
/insights (and the per-model Cost column) were unreliable. Hide them from
both terminal and gateway renderings.

The underlying data pipeline is untouched — sessions still store
cache_read_tokens, cache_write_tokens, and estimated_cost_usd; the web
server, /usage command, and status bar are unaffected. Only the
InsightsEngine display layer is trimmed.

Changes:
- format_terminal: drop 'Cache read / Cache write' line, drop 'Est. cost'
  from the Total tokens row, drop per-model 'Cost' column, drop the
  '* Cost N/A for custom/self-hosted' footnote.
- format_gateway: drop cache breakdown from Tokens line, drop 'Est. cost'
  line, drop per-model cost suffix.
- Tests updated to assert these strings are now absent.
