release: prep v3.4.0 for CRAN

[ehrlinger]

v3.4.0 CRAN release prep

Release-gate prep on top of merged main (includes #132 docs and #133 factor-partial fix). Version stays 3.4.0 (DESCRIPTION == NEWS; carries the 3.3.0 + 3.4.0 delta since CRAN 3.2.0).

Release gate — PASS ✅

Step	Result
R CMD check --as-cran with manual	Status: OK — 0 / 0 / 0
Tarball size	4.2 MB (< 5 MB)
Total check time	3m19s (vignette rebuild 36s, tests 33s) — well under 10 min
urlchecker::url_check()	17/17 correct
CRAN Cookbook audit	no \dontrun, \value on all exports, ≤2 cores, no forbidden writes, no raw Unicode in Rd, Title Case, quoted names + <doi:>
Reverse dependencies	0
Version grep (DESCRIPTION == NEWS)	both 3.4.0

The new live-fit uvarpro.qmd was the check-time watch-item — vignette rebuild stayed at 36s total, so no precompute needed. UBSAN is clean by verified mechanism (uvarpro() is synthetic-supervised; only isopro(method="unsupv") trips entry.c:184, still skipped).

Changes in this PR

• cran-comments.md — rewritten for 3.4.0 (was stale at v3.2.0): interpretable varPro partial scales, unsupervised wrappers, the gg_partial_rfsrc factor fix; test envs + UBSAN NOTE disposition refreshed.
• DESCRIPTION — Date → 2026-07-01.
• README.md (docs sweep) — added a pointer to the new uvarpro vignette (the unsupervised trio was undiscoverable from the README); refreshed the stale "Recent changes" (was stuck at v2.5/v2.6) to the v3.x line.

Docs sweep — consistent

Structural docs verified via the clean check (roxygen/man/\link resolve, pkgdown reference covers every export, NEWS covers new/changed exports, vignette \VignetteIndexEntry titles unique). Only the two README staleness items above needed fixing. The function-reference table intentionally delegates the varPro family to the vignette (left as-is).

Before submitting (yours to run)

• win-builder (R-devel/release/oldrel) + mac-builder
• devtools::submit_cran() (includes cran-comments.md verbatim)
• On acceptance: tag v3.4.0, GitHub Release
