Commit: fmt: keep a grammar rule’s parentheses whole, a rule’s continuation one level deeper
Body: The printer’s frame now knows a grammar { } body (FmtFrame.rules, set by fmt_opens_grammar on the line that opens it). On a line in such a body, reshape treats every ( group as sealed (a guard’s if(..), fail(..), a group): the grammar parser takes no break and no trailing comma inside them, so a long rule line breaks its action block or stays long. indent_of puts a body line that starts no rule (fmt_starts_rule: rule, entry, pub, @frame) one level deeper than the rules, so a rule broken by hand keeps its continuation, and formatting again changes nothing. Both steps of the brief in one commit. The badge is redrawn because the self-hosting share moved.

Tests: fmt_keeps_a_grammar_guard_whole (probe 1 + probe 2’s hand-broken rule) red on the unfixed binary (fmt: “the formatted file does not parse: Expected )”), passes now and is a fixed point; it::fmt:: 18 passed; tests/compiler –both-settings 422 passed; guard set 24 passed (sequences within its ceiling); clippy clean; pre-push-check ok; wip/y2c-properties packages/yaml/src/main.nika formats, passes nikaia check, and is a fixed point (fmt re-indents its unformatted action blocks)
