docs: trim repeated boilerplate in git, gitea, and bin skills

Finding 13: five blocks of near-identical wording were repeated across
skills within a plugin — the gitea "resolve owner and repo" step (5
skills), the 404-masks-403 note (6 files), the manual pagination
explanation (8 files), the git plugin's main/master force-push refusal
(7 files, some with multiple internal restatements), and the bin
skills' domain-glossary/ADR paragraph (5 skills). Tightened each
instance in place — same meaning, fewer words — rather than extracting
to a shared file, which ADR-0014's one-file-per-skill install
constraint rules out. Left the three git skills' structured-result
JSON shapes alone (coupled to the separate, out-of-scope git-orchestrate
merge candidate, finding 19).
