Code execution now uses a LanguageRegistry with built-in defaults
(bash, python, ruby, perl, javascript) that can be overridden by TOML
config files in /etc/orkmode/languages or ~/.config/orkmode/languages.
Match Emacs org-babel result formatting: fixed-width (": " prefix) for
output under 10 lines, #+begin_example blocks for 10+ lines
(org-babel-min-lines-for-block-output).
Fix insert_results duplication: the source block span end already points
to the start of the line after #+END_SRC, so searching for the next
newline skipped the existing #+RESULTS: line and prepended duplicates on
re-execution. Also handle replacing existing #+begin_example result blocks.
Fix parser: #+begin_example, comment, and export blocks were misparsed as
SourceBlock with a bogus language, causing "unsupported language" errors
on re-execution. Map them to their correct AST element kinds.
- execute <doc> — all blocks in document
- execute <doc> <section> — all blocks in subtree
- execute <doc> <section> <idx> — single block by index
- execute <doc> <section> <name> — block by #+NAME in section
- execute <doc> :<name> — named block anywhere in doc
Parser now extracts #+NAME: from block's affiliated keywords.
Supports bash, python, ruby, perl, and node interpreters.
Basic sandboxing via env_clear() and restricted PATH.
