Add [workspace] to excluded packages for worktree compatibility

rust_wasm_samples, hyperlight_wasm_macro, and component_sample were
missing empty [workspace] tables in their Cargo.toml files. Without
this, Cargo resolves to the main checkout's workspace root when run
from a git worktree, causing 'believes it's in a workspace' errors.
wasm_runtime already had this marker.
