WIP - initial commit: plugin-config UI inside wikilabs/bundler

[pmario]

Adds the plugin-config scaffold under plugins/wikilabs/bundler/tiddlers/:

ui/Plugins.tid New sidebar tab listing every $:/tags/PluginConfig with status pill, filter input, and "+ New plugin config" button.

ui/plugin-config/ canvas.tid — body-template root, transcludes 7 sections PluginsList.tid — sidebar list rendering status-pill.tid — draft / no-target / unbuilt / built pill helpers.tid — wlpc-collapsible procedure (state-persistent
replacement for

) and bundle-resolution
helpers (bundle-tids/lane-tids — currently
broken for multi-bundle filter resolution,
rewrite pending)
section-draft-banner — Activate banner for new configs section-header — config title + Verify/Build (Build is a stub
that writes a log; verify is a state setter)
section-identity — template dropdown, target plugin field,
version-policy select
section-pending — pending-changes detection via
modified > last-built (wired but no real
build sets last-built yet)
section-sources — three lanes (Sources / Skip this build /
Drop from plugin) with per-lane border accent;
Skip dropdown only lists already-included bundles
section-resolved — list + count of resolved tiddlers (count
broken for multi-bundle filter lanes —
rewrite pending using nested $list dispatch)
section-snapshot — single-button auto-snapshot to a Bundle
tagged $:/tags/Bundle $:/tags/Milestone

system/viewtemplate-cascade/$:/config/ViewTemplateBodyFilters/PluginConfig Routes $:/tags/PluginConfig tiddlers to the canvas body template.

styles/plugin-config-styles.tid Palette-aware styles for canvas, sections, collapsibles, lanes, pills. Uses TW core tc-{tiny|small|big}-gap-{left|right} classes for inline spacing where \whitespace trim strips it.

Known issues to address next:

• Bundle resolution for filter-tagged bundles inside :map / function bodies returns wrong counts; replace with nested wikitext $list rendering using the verified =>filter [subfilter] pattern.
• Real build wiring (currently a stub).
• Identity template seeding is unwired (dropdown sets the field but doesn't apply template metadata to the plugin tiddler yet).
