jmvergesandClaude Opus 5.5 9d6188c47c .ai import: type keeps the manual kerning of its text document (#6899) ...

The text document reader never read a story's manual kerning, so type
kerned by hand in a .ai or EPS editing copy came in with automatic
kerning on every pair and drifted from the file's page from each kerned
pair on. Envelopes of such type drew apart from their drawn art and
kept it.

Key 8 of a story's text holds the kerning as runs of characters (key 1),
each with a value in thousandths of an em (key 0 of key 0) or empty
where the automatic kerning applies. Each character with a value now
takes it as its Kerning, the space after it, and the style runs split
where the value changes. A value that can't be read keeps the automatic
kerning, a run whose length can't be read ends the runs there, and past
65,536 runs the characters keep the automatic kerning.

- ate.rs: Story reads the runs (manual_kerning) and node() splits its
  text runs at them (Kerns), with a unit test over values, style-run
  boundaries, hostile values and the laid-out gap, and one that pins
  the limit of runs.
- tests_native.rs: an imported story with kerned and automatic runs.
- docs/file-format-parity.md: status line, mapping line, revision row.
