ci/woodpecker/pr/ci Pipeline is pending
- Value guards now reject option-like values: --anything always, and single-dash flag shapes (-h, -i). Previously -b --help consumed --help as the body and performed the write (codex example: issue-close -i --help proceeding to 'Closed GitHub issue #--help'). Multi-char dash-leading text (-start of a list) stays a legal value. - Every remaining direct provider exec (gh/tea/CMD arrays across issue-create/edit/assign/list/view, milestone-*, pr-create/edit, pr-close, issue-close/reopen) wrapped with rc capture and normalized to exit 1 with a stderr message — provider exit 2 no longer collides with the reserved usage-error status. - All 16 usage-contract suites gained option-like and short-flag arms (16/16 green). Existing suites re-verified; test-pr-edit and test-issue-create-interactive-auth fail identically with these changes stashed (environment-coupled, not regressions; documented).
