Add the Category -> Tag taxonomy the mood surface was missing and the
free-text note the web form could never write, then surface both on the
Insights mood page.
Schema (migration 0101): a global MoodTagCategory -> MoodTag catalog
plus a MoodEntryTagLink join, seeded with a default five-category set
(i18n-keyed labels, Lucide icons). Purely additive — the legacy flat
MoodEntry.tags JSON column, the GLP-1 quick-tags, and the Telegram /
MoodLog sync are untouched; an entry can carry both axes.
Capture: the mood-logging form and the edit sheet gain a Textarea for
the note (model + API already accepted it) and an icon-chip picker over
the taxonomy catalog (GET /api/mood/tags). Create / update resolve the
picked keys to links; unknown keys drop silently against the catalog.
Insights: a structured-tag breakdown (icon + per-tag avg-mood lift) and
a notes timeline join the existing distribution / weekday / flat-tag
sections. The aggregate extension also fixes the flat-tag axis, which
read the raw JSON string and so never populated.
i18n across all six locales. Tests cover the taxonomy aggregation, the
note round-trip, the structured-tag schema, and the notes timeline.
