Merge pull request '#69 dev→main: release v26.06.04.0' from dev into main

Operator-confirmed on a fresh build: both the tag-chip and suggestion
kebabs still never opened. The prior 8326e54 'fix' only wrapped them in a
<span @click.stop> — inert for SuggestionItem (no parent capture) — and
never addressed why the `#activator`/`v-bind="props"` click failed to
toggle the menu inside the teleported ImageViewer modal. The dialogs in
that same modal open via v-model and work, so drive the menus the same way:

- The activator (v-btn / v-icon) toggles a reactive flag with @click.stop
  (which also shields the chip's close button / any parent).
- The v-menu binds that flag (v-model / :model-value) and uses
  activator="parent" with :open-on-click="false" purely for positioning,
  so opening no longer depends on Vuetify's activator-click path.
- TagPanel tracks a single openTagId (one chip menu open at a time).

+"""image_record.siglip_embedding: HNSW cosine index for "more like this"
+
+Revision ID: 0036
+Revises: 0035
+Create Date: 2026-06-04
+
+Gallery Phase 3 (visual similarity search) ranks images by
+`siglip_embedding.cosine_distance(source_embedding)`. Without an index that's
+a sequential scan computing a 1152-dim distance for every row — fine at small
+scale, but it grows linearly with the library. Add an HNSW index with
+`vector_cosine_ops` so the top-N nearest search is sub-50ms ANN.
+
+1152 dims is under pgvector's 2000-dim HNSW limit, so HNSW (no training,
+better recall than IVFFlat) is the right choice. ONE-TIME COST: building the
+index over the existing embeddings (~57k vectors on the operator's library)
+locks image_record for ~30-60s during this migration on deploy — acceptable
+for a single-operator homelab. NULL embeddings (videos / not-yet-embedded
+rows) are simply not indexed.
