docs: decouple roadmap themes from version pins

Convert the ROADMAP version-theme table to a theme-ordered table without hard version numbers on upcoming rows. Shipped themes note their release in Status for reference (Shipped (v0.x.0)); upcoming themes (5.2 sweep, Stable) carry no version, so shipping another example/skill no longer forces a roadmap renumber. Candidate-pool heading de-pinned too. Current line untouched (release-doc-sync owns it).

+Themes are listed in order. Shipped themes note the release they landed in (for reference,
+not a commitment); upcoming themes are intentionally **not** pinned to a version number, so
+shipping another example or skill never forces a roadmap renumber. The release pipeline
+derives the actual version from conventional-commit types.

 Audit pass on v0.1.0 content: standards-version markers bumped from `1.9.1` to `1.9.4` across all skills, rules, AGENTS.md, CLAUDE.md, and ROADMAP.md. Verified the `bpy_extras.anim_utils.action_ensure_channelbag_for_slot` import path against the current Blender 5.1 API reference and removed the stale "verify before production" caveat in `slotted-actions-animation/SKILL.md`.
