All function names referenced via {.fun …} in cli-style messages are
exported in NAMESPACE, so {.help …} is the appropriate markup — it
renders as a clickable help link rather than plain function styling.

Rewrites message_(), warning_(), stop_() to use cli::cli_inform(),
cli::cli_warn(), and cli::cli_abort() when the cli package is available,
with a fully functional plain-text fallback for environments without cli.
Key changes:
- New cli_to_plain() helper converts cli inline markup ({.fun}, {.arg},
{.val}, {.field}, {.cls}, {.pkg}, {.href}, {.url}, etc.) to readable
plain-text equivalents for the non-cli fallback path
- word_wrap() simplified: drops add_fn, ANSI re-index algorithm, RStudio
link injection, and operator spacing hack; returns pasted input unchanged
when cli is available
- stop_() no longer references AMR_env$cli_abort; uses pkg_is_available()
directly; passes sys.call() objects to cli::cli_abort() call= argument
- Removed add_fn parameter from message_(), warning_(), and word_wrap()
- All call sites across R/ updated: add_fn arguments removed, some paste0-
based string construction converted to cli glue syntax ({.fun as.mo},
{.arg col_mo}, {n} results, etc.)
- cli already listed in Suggests; no DESCRIPTION dependency changes needed
