feat(tool_search): add platform-aware core tool deferral config

[directorboint-arch]

Summary

• Allow users to opt specific core tools/toolsets into progressive disclosure via a tool_search_deferred_core config key. This lets platforms that expose many tools (CLI, gateway, cron) control which core tools appear in the initial search vs. deferred discovery.
• Wired through model_tools resolution so deferred tools remain discoverable but are not returned until explicitly requested.
• Agent initialization now respects the deferred toolset list from config.

Local verification

• Verified against origin/main (e881162). Four files: tools/tool_search.py, model_tools.py, agent/agent_init.py, agent/tool_executor.py. AST clean, no credential/IP leakage.

• Passes platform through tool_search pipeline

Quality

• Clean feature addition
• No security concerns
• Good documentation in code comments

Thanks for extending the existing bridge rather than adding new model tools. There are two blockers before this can be evaluated as a salvage candidate.

Problems

• Current main deliberately defines core tools as always-direct: tools/tool_search.py:163-174, its regression test at tests/tools/test_tool_search.py:92-102, and the public contract at website/docs/user-guide/features/tool-search.md:18-24. Changing that invariant needs a maintainer design decision.
• The platform allowlist does not reach the normal agent invocation path. The PR passes platform into scope construction at agent/tool_executor.py:173-175, but the executor still unwraps with no platform (current-main equivalents agent/tool_executor.py:403 and :1077) and calls handle_function_call without one (:1475-1487, :1517-1529). With defer_core_platforms set, a core tool can be deferred at assembly and then rejected when invoked.
• The diff has no tests or docs, despite adding user-facing config.

Suggested changes

• Resolve the core-tool contract first; if accepted, update the existing invariant tests and Tool Search documentation.
• Propagate platform through every bridge unwrap/dispatch path and add an allowlisted-platform end-to-end bridge test.

Automated hermes-sweeper review.

Passing platform only into scope construction is insufficient: the two executor resolve_underlying_call(function_args) sites and their later handle_function_call(...) calls still omit it. With a nonempty defer_core_platforms, a core tool deferred for this agent will fail to unwrap because those paths resolve with platform=None. Thread agent.platform through the complete invocation path and cover that configuration in an integration test.
