fix: complete version-aware reconcile against real URL shapes; release v1.2.2v1.2.2

1.2.1 made the bundled-dep reconcile version-aware but _url_version
mis-parsed several real-world URL shapes, so 1.2.1 was never correct in
the field (found by running mkhint -C --force neovim against the live
0.12.4 hint).

_url_version now derives the version by stripping the URL's own github
repo name from the basename:
- dep names containing digits/dashes (lua-compat-5.3) parse correctly
  instead of splitting the name as a version
- a bare-tag basename with no name prefix is taken as the whole version,
  fixing package-rev suffixes (luv 1.52.1-0 was truncated to 0)
- non-github and the shared neovim/deps blob host fall back to the
  trailing-version/sha heuristic

_url_repo is lowercased so JuliaStrings/utf8proc matches
juliastrings/utf8proc (github repos are case-insensitive); utf8proc had
reported no-match and appeared in the manifest-only FYI.

Verified against all 13 live neovim 0.12.4 bundled deps: all match and
report current, no false change, a real bump still detected. Adds
T-BM22 (one case per URL-shape class) and T-BM23 (case-insensitive
repo match); T-BM17 unchanged. 182 passed.

Bump MKHINT_VERSION and man title to 1.2.2, rebuild mkhint.1.gz.
