tinyrox drops roxygen @section blocks when generating Rd

[TroyHernandez]

Summary

tinyrox::document() silently drops @section <Name>: roxygen blocks. The function still generates the rest of the .Rd (description, params, return) but the \section{...}{...} block never appears in the output.

Minimal repro

#' Example function
#'
#' Main description.
#'
#' @section Permissions:
#' This text should appear in generated Rd.
#' @export
f <- function() NULL

Run tinyrox::document().

Expected: generated .Rd contains a \section{Permissions}{This text should appear in generated Rd.} block.

Actual: the section is omitted with no warning. The .Rd looks fine apart from the missing block.

Why it matters

Without a warning, a caller has no signal that their docs are incomplete. We hit this on corteza::subagent_spawn() where a @section Permissions: block documenting the no-mid-run-escalation invariant was silently dropped, so ?subagent_spawn showed nothing — see cornball-ai/corteza#77 for the fix (inlined the text into the main description as a workaround).

Workarounds

1. Inline the section content into the main description paragraph.
2. Use a ## Heading line inside the description (roxygen2-style markdown sections).

Suggested resolution

Either render @section into \section{...}{...} in the generated .Rd, or warn on encountered-but-unsupported roxygen tags so silent drops become loud.
