* feat(foundry): add experimental hosted tool factories on FoundryChatClient

Adds eight new `@experimental` static factory methods on `FoundryChatClient`
covering Foundry-hosted tools that previously had no helper:

- get_azure_ai_search_tool
- get_sharepoint_tool
- get_fabric_tool
- get_memory_search_tool
- get_computer_use_tool
- get_browser_automation_tool
- get_bing_custom_search_tool
- get_a2a_tool

All factories are marked with the new `ExperimentalFeature.FOUNDRY_TOOLS` tag
and resolve the underlying `azure-ai-projects` preview classes lazily through
a `_require_sdk_class` helper so older SDK versions still import cleanly and
fail with a clear `ImportError` only on use.

Tests cover each factory's return type and field wiring, the experimental
metadata, and the missing-SDK-class fallback.

* test(foundry): address review comments on tool-factory tests

* Skip preview-tool tests gracefully (`_skip_if_sdk_class_missing`) when
  the installed `azure-ai-projects` does not expose the required preview
  class, matching the lazy-import guard in production code so the test
  suite stays green on older SDK installs.
* Add `filterwarnings("ignore::FutureWarning")` to each new tool-factory
  test (and the parametrized metadata test) so they remain stable under
  strict warning configurations \u2014 the global dedup in
  `_feature_stage._WARNED_FEATURES` makes `pytest.warns` brittle across
  ordered runs.
* Use `monkeypatch.setattr(..., None, raising=False)` instead of
  `delattr` in the missing-SDK-class test so it works for modules that
  implement PEP 562 `__getattr__`.
* Split the long `get_bing_custom_search_tool` return into two lines for
  readability.

* fix(foundry): harden tool-factory kwargs against silent override

* Reorder the dict-literal kwargs assembly in get_azure_ai_search_tool,
  get_memory_search_tool, and get_bing_custom_search_tool so explicit
  parameters always take precedence over **kwargs (matching the safe
  pattern already used in get_a2a_tool). This prevents a caller
  passing `project_connection_id`, `index_name`, `memory_store_name`,
  `scope`, or `instance_name` through `**kwargs` from silently
  overriding the explicit security-sensitive arguments.
* Update the README experimental note to reflect once-per-feature-id
  dedup semantics of `_feature_stage._WARNED_FEATURES` rather than
  claiming a per-factory "first use" warning.

* feat(foundry): split FOUNDRY_TOOLS / FOUNDRY_PREVIEW_TOOLS, add bing-grounding

- Add ExperimentalFeature.FOUNDRY_PREVIEW_TOOLS to distinguish wrappers around
  preview Foundry SDK tool classes (Sharepoint/Fabric/Memory/ComputerUse/
  BrowserAutomation/BingCustomSearch/A2A) from FOUNDRY_TOOLS, which is for
  GA-SDK wrappers that are simply new in agent-framework-foundry
  (AzureAISearch, BingGrounding).
- Add get_bing_grounding_tool factory and a 'Choosing a web grounding tool'
  comparison block on get_web_search_tool / get_bing_grounding_tool /
  get_bing_custom_search_tool docstrings.
- Drop the _require_sdk_class lazy resolver: every guarded class is available
  at azure-ai-projects>=2.1.0 (the package floor), so import them eagerly.
  Concrete return types replace 'Any'.
- README: split the experimental factories into two tables, one per feature
  flag, with a note explaining the distinction.
- Tests: split into FOUNDRY_TOOLS / FOUNDRY_PREVIEW_TOOLS factory cases;
  drop the obsolete missing-SDK-class ImportError test.
