dsROCrate 0.2.1

Bug Fixes

• Removed a duplicate, conflicting definition of as.data.frame.safe_call() (two files each defined this S3 method with different output columns; only one could ever take effect, silently). The safe-call.R version — timestamp, user, r_cmd, fx, args, session, profile — is now the sole implementation.
• Fixed print.safe_symbol() referencing stale column/parent fields left over from before the 0.2.0 symbol-model refactor; it now correctly displays the symbol's asset, expr, and session (guarding on both NULL and NA, since these fields default to NA_character_).
• Fixed as.data.frame.symbol_registry(), which previously iterated over the columns of the underlying tibble instead of its rows (via lapply() on a data frame), causing it to error whenever called on a non-empty registry. It also referenced non-existent parent/column fields. The method now simply returns x$symbols coerced to a data frame, which already carries the correct columns.
• Fixed register_symbol() erroring on a brand-new, empty registry (the very first symbol registered in any session): the emptiness check compared nrow() of a plain, pre-tibble list() before checking length(), producing a zero-length logical passed to ||. The length() check is now evaluated first, so it short-circuits correctly.
• Fixed as.data.frame.safe_call()'s args column having an unstable name and shape depending on how many arguments the underlying call had (a single-argument call collapsed the column into one named after that argument, e.g. x; multiple arguments spread into several columns instead of one). The argument list is now wrapped with I(list(...)) so it always appears as a single, reliably-named args list-column.
• Added regression tests for safe_call()/as.data.frame.safe_call(), print.safe_symbol(), and register_symbol()/as.data.frame.symbol_registry(), none of which previously had any test coverage.

Internal Changes

• Removed unused internal helpers: has_symbol()/has_symbol.symbol_registry() (and its S3 export) and safe_symbol_reference()/new_safe_symbol_reference(), none of which were called anywhere in the package.
• Removed leftover commented-out code from safe_symbol() and print.safe_call().
• Added roxygen2 documentation (@param, @returns, @keywords internal, @noRd) and explanatory comments to the internal symbol-tracking functions introduced in 0.2.0 (safe_call(), safe_symbol(), safe_reference(), symbol_registry(), and their supporting utilities), with no change in behaviour.
• Updated spell-check WORDLIST.
• Re-rendered vignettes to refresh example output.
