v1.4.0 — Other custom-task setup

Other can now be configured from Set Up CI with an explicit single-call or OpenCode mode, an exact eligible model/evidence choice, editable literal templates/prompts, bounded inputs/resources, permitted paths and maintainer-owned validation. The preview explains report-only versus disposable-edit capabilities and keeps missing validation unverified.

Mode changes invalidate the pick while retaining its label and author text. Explorer/reload/edit and legacy transitions preserve intent; old named drafts remain readable. Custom drafts use a UTF-8 byte bound, remove stale overflow copies and display an overflow warning. Pending integrations remain unselectable; no runtime activation or deployment.

Validation: 154 unit and 21 integration tests; TypeScript, lint (14 existing warnings, zero errors), production build; Playwright execution 22, catalog 12 and public/legacy 12 checks, including desktop/mobile, keyboard selection, literal preview, both modes, mode invalidation and legacy edits. Self-review fixed prompt label stability and bounded-draft edge cases. Existing bundle warning remains.

Release: frontend 1.3.1 -> 1.4.0 (MINOR), a backward-compatible custom setup workflow. Backend Other Jenkins stages are delivered separately; agent 1.7.0 remains unchanged. Publishing does not change deployment pins.
