Parinfer for Nova

Parinfer for Panic Nova:
keep parentheses and indentation in agreement as you edit Lisp code, so you can
manage structure by indentation (or by parens) without fighting the brackets.

Works with Clojure/ClojureScript (and other Lisps if their syntaxes are
installed): .clj, .cljs, .cljc, .edn, .bb, .scm, .lisp, .fnl, …

Modes

• Indent Mode (default) — infers close-parens from your indentation (it may
  add or remove parens). The classic "never touch parens" experience.
• Paren Mode — preserves the parens you type and adjusts indentation to
  match. Safe and predictable; great for existing files.

Smart Mode is intentionally not included: it needs precise change deltas that
Nova's editor API doesn't expose, which makes it unreliable.

Usage

Parinfer is off by default. Enable it via:

• Editor → Parinfer: Toggle, or Use Paren Mode / Use Indent Mode
  (also in the Command Palette), or
• Settings → enable Parinfer and pick a mode (global or per-workspace).

A brief notification confirms the active mode when you toggle or switch. (Nova
has no extension API for a status-bar indicator yet, so the notification stands
in for one.)

Notes / limitations

• It needs a Lisp syntax to be active for the file (e.g. the Clojure
  extension provides the clojure syntax).
• Parinfer runs on the whole buffer per change; very large files are skipped.
• Programmatic edits may not coalesce into Nova's native undo as cleanly as
  ordinary typing.
