KenM76andClaude Opus 5.5 0457aa88f9 fix(redact): Q inside a text object restores the text matrices; revert the render change

Review on #4831 pointed out the PDF Association's erratum to ISO 32000-2
(pdf-association/pdf-issues #368): inside a text object, q/Q also save and
restore Tm and Tlm (§9.4.1, referenced from §8.4.2). Acrobat 26.2 agrees on
a synthetic PDF 2.0 page. The renderer on main already did this, so the
previous commit's hayro-interpret patch (67) was wrong: it is reverted here,
with its vendor/README row and the render tests.

The real disagreement was in the redactor's own interpreter, which kept Tm
and Tlm across Q. Find took its boxes from the renderer's text, the redactor
measured the glyphs elsewhere, and redact_apply refused on residue. Its
state stack now holds (Gs, Tm, Tlm) and Q restores all three.

Test: it::redact_text_after_q, end to end on %PDF-2.0 fixtures, three cases
(font change inside q/Q; q 100 0 Td Q; the same followed by T*). With the
redactor change reverted, each case fails on its own at redact_apply. With
only Tm restored, the T* case fails.
