Assess discrete task progress motion

Assess and, if useful, implement one-shot progress segment, count and current-task transitions in ComposerTasksBadge. Check overlap with PR #10128. No recurring animation, fake progress, or per-frame React state.

Requested by Alex after the T3 UI motion audit. First record an independent Astra-medium accept/revise/reject verdict with source evidence. Accepted changes should end in small focused PRs; do not implement a rejected suggestion.

Use the installed shadcn-motion-ui skill and Human Interface Craft guidelines (feedback, relationship, continuity, accessibility, signature moments). Consult current official docs, reuse local primitives, verify installed API compatibility and add exact source references. Respect native platforms, reduced motion, interruptions, responsiveness, focus, and performance. No continuous repaint loops or framework rewrites.

Acceptance:

• Independent assessment and overlap check recorded.
• Accepted scope implemented and focused checks pass, or rejection/dependency documented.
• Best-effort independent cross-provider review recorded.
• Real before/after motion evidence and PR linked, with any missing evidence disclosed as a draft-readiness gap.

Do not change live user data, the dirty primary checkout, existing Stash worktree, or unrelated work. No merge or deployment is requested.

Start at the ComposerTasksBadge entry point and compare the requested scope with PR #10128. Record an independent Astra-medium verdict using the installed shadcn-motion-ui skill, Human Interface Craft guidelines, and current official docs, checking API compatibility and local primitives. Done means the accepted scope is implemented in a focused PR with the required checks, review, and before/after motion evidence, or the rejection and dependency are documented.
