docs: enable roxygen2 markdown package-wide

Add Roxygen: list(markdown = TRUE) to DESCRIPTION so devtools::document()
auto-converts backticks / [fn()] / [pkg::fn()] in source roxygen to
\code{} / \link{} / \link[pkg]{} in the generated Rd. Existing Rd-style
markup keeps working; both styles now coexist. Saves the manual
conversion work the Copilot review on PR #94 flagged.

Two source-roxygen edits needed to keep R CMD check clean under markdown:
- R/help.R: randomForest[SRC] -> randomForestSRC (markdown read [SRC]
  as an unfinished link reference, producing a missing-link warning).
- R/gg_rfsrc.R::bootstrap_survival: 95\% -> 95% (markdown over-escaped
  the backslash, producing a malformed Rd with shifted section order).

Regenerates all 31 Rd files. No functional or rendered-content change.

+* Documentation: enable roxygen2 markdown package-wide via
+  `Roxygen: list(markdown = TRUE)` in `DESCRIPTION`. New roxygen blocks
+  can use backticks and `[fn()]` link syntax; existing `\code{}` /
+  `\link{}` markup keeps working. Two source-roxygen edits to keep
+  R CMD check clean: `randomForest[SRC]` in `R/help.R` (markdown read
+  it as an unfinished link) becomes plain `randomForestSRC`; the `95\%`
+  escape in `R/gg_rfsrc.R::bootstrap_survival` becomes a literal `95%`.
+  No API or rendered-doc behavioural change beyond the conventions
+  switch.
 * New `gg_isopro()` and `plot.gg_isopro()`: tidy wrapper and ranked-elbow +
   density visualisation for `varPro::isopro` isolation-forest anomaly
   scores. `plot.gg_isopro()` takes `panel = c("both", "elbow", "density")`
