A load freed only the parsed trip's nodes (Json.free) and kept every string the parser made, because
a loader might keep one; free_all freed every string and every key, so on a tree a migration had
added a literal to (`Value.put(v, "sver", Value.str("2"))`) it freed the literal and aborted.
- The parser marks the string values it makes (JP_OWNED, in the node's otherwise unused num) and
interns object keys (a few names, never freed); free_all frees only marked strings, never keys,
and a list's spares too. A setter that gives a marked node other text (value_set_str/_strs,
value_into_str/_strs, value_become) frees the parser's text first. value_as_int / _as_float read a
string as 0 as before.
- ludic.base sv_str returns intern(...): every package load that keeps a text read from a section
(minimap labels, a Thing's look, photo tags and files, an effect's label, ...) holds its own copy.
Golden json_free_edited: parse, put a literal key and string in, set a string, keep an interned copy,
free_all - 1100 loads: the copy reads on and nothing grows (the toolchain before this aborts, 134).
Tests: ludic.save, base, settings, minimap, things, photo, effects; json_saves, value_list_regrow; the
36 ui examples.

A mechanic package depends on ludic.base and nothing else: ports (records of
function values for now) for questions, queues for facts, verbs for changes,
phases for order and its own versioned save section. The runner inits, resets,
saves and loads systems in the order added and ticks them phase by phase; a
missing save section is a reset. Tests for each piece and a worked route
between two toy mechanics live under tests/. The old ludic.core (engine ECS
components) is used by examples/library and stays.
