v0.2.6 — Nested link fix, slider authoritative for taxonomies

Bugfix

• Nested / broken markdown links. A source like `[Kdenlive](/x)` (which can appear after a re-accepted suggestion) used to leave dangling `](/url)` fragments that re-introduced the inner phrase as a phantom token. The stripper now peels the innermost match first and repeats until clean. Same fix in the frontend context preview's skip-zones.
• Phrase-length slider is now authoritative for every target type. Previously taxonomy targets bypassed it (so single-word values surfaced even at slider=2+), which contradicted the editor's intent. To see single-word taxonomy matches, drag the slider to 1.

Improved

• Taxonomy-routes admin help text uses `tag` as the example instead of the more specific `distro`.
