chore(release): bump version to 0.2.0

Minor feature release over v0.1.0 (124 commits). Highlights:
- Drop-in upstream g:vimwiki_list / g:vimwiki_* config (Vim) + global
  per-wiki defaults shorthand (both clients)
- Programmatic coc.nvim registration (no hand-written coc-settings.json)
- :NuwikiTOC / GenerateLinks / GenerateTagLinks insert at the cursor line;
  scoped :NuwikiGenerateLinks <path> wired up
- HTML export: heading id anchors, div.toc wrapper, section numbering;
  toc_header/level honoured in single-wiki config
- The full P3 config/command/mapping parity batch + R1–R18 review fixes

Bumps the workspace version, the inter-crate path-dep requirements, and
g:nuwiki_version.
