SPECS: Add lazygit Go dependencies

[cl2t]

Summary

Add the Go library dependencies needed to package lazygit (a terminal UI
for git). All 26 packages were generated with go2spec and hand-tuned
(official GitHub sources, correct licenses/sha256, trimmed descriptions,
%doc before %license), one package per commit. Each one builds
successfully on OBS for both x86_64 and riscv64.

Notable trims/fixes:

• go-github-cli-go-gh-v2: trimmed to pkg/auth+pkg/config (lazygit only
  uses those), dropping the large survey/sprig/chroma/glamour dependency tree.
• go-github-aybabtme-humanlog: dropped cmd/ (urfave/cli, rgbterm not needed).
• go-github-jesseduffield-generics: dropped slices//list/ (incompatible
  with the packaged x/exp; only maps/set/orderedset are used downstream).
• commit-pinned snapshots use 0+gitYYYYMMDD.<short> with the packaging date.
• env-sensitive/self-tests (go-deadlock, karimkhaleel/jsonschema, fsnotify,
  clipboard) are tolerated/trimmed with rationale comments.

go-github-gdamore-tcell-v3 and lazygit itself are NOT in this PR: tcell/v3
v3.4.0 requires clipperhouse/uax29/v2 v2.7.0 while main currently ships
v2.3.0 (the graphemes.FromBytes API changed), which also affects 6 other
existing packages. That version bump needs maintainer coordination and will
be handled separately.
