Built-in Claude provider now uses the CLIProxy root URL instead of /api/provider/claude (which 404'd since base CLIProxy registers /v1/messages at root). Repairs stale local Claude settings, keeps non-Claude providers on their scoped routes, and applies the same root-URL rule to the ccs api create --cliproxy-provider claude bridge path via a shared buildCliproxyProviderPath helper. Closes#1545.
Align with claudecode-env-stripping.test.ts style — explain why
CLAUDE_CONFIG_DIR is cleared in beforeEach for consistency across
test files.

When tests run inside a CCS-managed Claude session, host env vars
(CLAUDE_CONFIG_DIR, CCS_PROFILE_TYPE) leak into subprocess spawns
and fixture setup, causing 9 test failures:
- persist-command-handler: reads real symlinked settings.json instead
of temp fixture because CLAUDE_CONFIG_DIR overrides scoped CCS_HOME
- websearch-transformer: hook silently exits via shouldSkipHook()
because CCS_PROFILE_TYPE=account triggers native_account_profile skip
- claudecode-env-stripping: normalizeSharedPluginMetadataPaths receives
leaked CLAUDE_CONFIG_DIR instead of undefined for default profiles
Fix: clear CCS-managed env vars in beforeEach and neutralize
CCS_PROFILE_TYPE in subprocess env blocks.
