feat(toolbox-llamaindex)!: Base toolbox-llamaindex over toolbox-core

[anubhav756]

Similar to #229 but for toolbox-llamaindex.

This PR introduces a new dependency on the foundational library toolbox-core.

Breaking Changes

This PR introduces changes to how "strictness" is handled across several toolbox functions. The strict flag has been removed from load_tool, aload_tool, add_auth_token_getter(s), and bind_param(s). Additionally, the default behavior of load_toolset for strict=False has changed.

Why?

Enforces more explicit error handling and reduce ambiguity, particularly in scenarios where unused configurations might otherwise be silently ignored.

* (a)load_tool do not support strict flag now:

Before

tool = await client.aload_tool("my-tool", strict=True)

After

tool = await client.aload_tool("my-tool")
tool = await client.aload_tool("my-tool", strict=True) # <-- Error

* (a)load_toolset functionality changes for strict=False

• Before

tools = toolbox.load_toolset(
    auth_token_getters={...},
    bound_params={...},
    strict=False,
)

Does not throw error if none of the loaded tools use a given auth token getter or bound param. Only throws a warning.

After

tools = toolbox.load_toolset(
    auth_token_getters={...},
    bound_params={...},
    # strict=False, <-- default
)

Throws error if none of the loaded tools use a given auth token getter or bound param.

* add_auth_token_getter(s) do not support strict flag

Before

# Warning
auth_tool = tool.add_auth_token_getters(
    {"unused_auth": ...},
    strict=False,
)

# Error
auth_tool = tool.add_auth_token_getters(
    {"unused_auth": ...},
    # strict=True, <-- default
)

After

# Error
auth_tool = tool.add_auth_token_getters(
    {"unused_auth": ...},
)

* bind_param(s) do not support strict flag

Before

# Warning
bound_tool = tool.bind_params(
    {"unused_param": ...},
    strict=False,
)

# Error
bound_tool = tool.bind_params(
    {"unused_param": ...},
    # strict=True, <-- default
)

After

# Error
bound_tool = tool.bind_params(
    {"unused_param": ...},
)
