* feat(question-types): add THUMBS contracts, scoring, and seed

Introduce the THUMBS question type (id 14) with boolean answer data,
codec, auto-grading, Zod validation, DB seed/schema docs, and binary
normalize support shared with TRUE_FALSE. Dashboard wiring is deferred.

* feat(dashboard): wire THUMBS question type into exercise UI

Connect THUMBS option sync in edit/view modes, labels, picker icon,
and locale strings so the existing contracts surface in the dashboard.

* fix(ui): polish thumbs question UI and move premium upgrade icon

Widen thumbs Yes/No toggles, inherit selected icon color via custom class,
replace badge-based review correctness with solid fill states and bare
Check/X icons, add a success pill in preview, and place the premium
upgrade icon at the end of the question type select row.

* fix(ui): align thumbs review colors with prototypes

Tune correct/incorrect selected states so review buttons use dark
emerald/red content colors on solid fills, matching the design comps.

* fix(ui): address remaining PR review comments

Use a shared timestamp local in thumbs edit fallback options.
Move border-beam animation-delay after the animation shorthand.
Alias --spacing to --ui-spacing for tw-animate compatibility.

* fix(db): sync question_type sequence before seeding new types

Avoid duplicate key errors when question_type_id_seq lags behind rows
inserted via restore or explicit ids (e.g. THUMBS on restored databases).

* fix(exercise): resolve thumbs review label ICU crash

Remove {value} ICU placeholder from thumbs.review.correct_answer_label
since labels are resolved at map-build time without context. Append the
dynamic yes/no label in thumbs-review-toggle instead.

Also bind question points through the questionnaire store index to avoid
the Svelte non-reactive property binding warning in edit-mode.

* docs(agent): add THUMBS guidance and sync question type docs

Add shared agent question-type guide helpers in @cio/question-types and
use them across the teacher prompt, add/update_questions tool schemas,
legacy ai-assistant schemas, and MCP exercise tools.

- Document when to use THUMBS (Yes/No sentiment) vs TRUE_FALSE (factual)
- Fix stale MCP question type ids and add THUMBS=14
- Exclude disabled MATCHING/HOTSPOT from enabled type lists

* fix(thumbs): clarify auto-grading and add editable option labels

THUMBS is auto-graded like TRUE_FALSE; the difference is thumbs UI with
customizable Yes/No-style labels and the teacher selecting the correct
option. Render take/preview/review from question.options labels and add
label inputs in the thumbs edit renderer. Update agent and MCP docs to
stop implying THUMBS is manual or non-gradable.

* chore(mcp): bump version to 0.0.10

Co-authored-by: Rotimi Best <rotimi-best@users.noreply.github.com>

* fix(question-types): make THUMBS open-ended with no correct answer

THUMBS is a sentiment/poll question type, not an auto-graded binary like
TRUE_FALSE. Remove correct-answer UI, scoring, and validation; update agent
and MCP docs accordingly.

* fix(dashboard): stop treating THUMBS as auto-graded in editor validation

Normalize thumbs questions on load/save, show an Open-ended badge instead
of Auto, and only enforce points/correct-answer rules on auto-gradable types.

* revert(dashboard): remove unsolicited open-ended grading badge

THUMBS uses the existing Manual badge like other non-auto-gradable types.

* fix(exercise): show question title validation errors in editor

Display mapped title errors beneath the question title input instead of
only highlighting the question card border. Pass the exercise entity to
mapZodErrorsToTranslations so messages resolve to validations.exercise.*
keys, and use a translated snackbar key for save validation failures.

* fix(mcp): build workspace deps before MCP publish bundle

The MCP esbuild step imports @cio/question-types and @cio/utils dist
outputs. CI failed on a clean checkout because mcp:build only built the
MCP package itself. Build those dependencies first so 0.0.10 can publish.
