ToolSpecLoader — discover and load all YAML tool specs from a directory.
Convention: one YAML file per tool, named exactly like the Python function
that implements it (e.g. resolve_season_destination.yaml).

Load every {tool}.yaml under specs_dir into a {name -> ToolSpec} mapping.

Mapping from tool name to its parsed ToolSpec.
Raises:
ToolSpecError: if a spec is malformed, or if the filename doesn't
match the 'name' field inside the YAML.
