release: 0.2.6 (docs.rs fix + README table reordering) (#36)

* fix(docs-rs): rename `doc_auto_cfg` to `doc_cfg` after Rust 1.92 merge

`doc_auto_cfg` was removed in Rust 1.92.0 and folded back into
`doc_cfg` (rust-lang/rust#138907). docs.rs builds with the latest
nightly and sets `--cfg docsrs`, so the previous

    #![cfg_attr(docsrs, feature(doc_auto_cfg))]

aborts compilation with E0557 on every published 0.2.x. GitHub CI
never tripped this — stable rustc ignores the line because nothing
sets the `docsrs` cfg there.

Switch all three published library crates (`wickra`, `wickra-core`,
`wickra-data`) to the merged-into `doc_cfg` gate. Same intent, same
on-docs.rs output, builds again on nightly.

* docs(readme): float Wickra to the top of the comparison tables

Reorders the "Why Wickra exists" library-comparison table and the two
benchmark headers so Wickra is the first row (with a ★ marker) instead
of the last. The previous order placed Wickra at the bottom, which
buries the only row a reader landing on the README is here to compare
against. Same column data, same ★/winner annotations, just the row
order flipped and a ★ prefix on the Wickra label.

Mirrored across the umbrella README and every binding README so the
crates.io / PyPI / npm landing pages stay in sync.

* release: bump workspace + bindings to 0.2.6

Workspace, every binding (Python, Node, Node platform stubs), the
release.yml comment and the CHANGELOG all move together to 0.2.6 so
the next tagged release lines every artefact up.

0.2.6 carries two changes from the [0.2.6] CHANGELOG entry:
- fix(docs-rs): swap the now-removed `doc_auto_cfg` feature gate for
  the merged-into `doc_cfg` so docs.rs nightly builds resume.
- docs(readme): float ★ Wickra to the top of every comparison table
  across the umbrella + binding READMEs.

wickra-win32-arm64-msvc stays excluded for this release with the same
npm spam-filter rationale that held for 0.2.5.

+## [0.2.6] - 2026-05-24
+
+### Fixed
+- **docs.rs build.** Rust 1.92 removed the `doc_auto_cfg` feature gate
+  and folded it back into `doc_cfg` (rust-lang/rust#138907). docs.rs
+  builds against the latest nightly and sets `--cfg docsrs`, so every
+  published 0.2.x failed with E0557 on the
+  `#![cfg_attr(docsrs, feature(doc_auto_cfg))]` line at the top of
+  `wickra`, `wickra-core`, and `wickra-data`. GitHub CI didn't see
+  this — stable rustc never enables the `docsrs` cfg. The three
+  library crates now gate on `doc_cfg` (same intent, same rendered
+  output on docs.rs, builds again on nightly).
+
+### Changed
+- **README — Wickra is now the top row of every comparison table.**
+  The "Why Wickra exists" library matrix and the per-indicator
+  benchmark tables previously placed Wickra at the bottom; a reader
+  landing on the README is here to compare *against* Wickra, so the
+  pivot row belongs at the top with a ★ marker. Same column data,
+  same winner annotations — only row order changed. Mirrored across
+  the umbrella README and every binding README so crates.io / PyPI /
+  npm landing pages stay in sync.
