Adds a Gantt viewlet to the Tracker, plus the filter/search rework the Gantt toolbar shares with the List and Kanban viewlets. Scope, roughly in the order the feature grew: * Read-only Gantt viewlet: time-scale canvas, sidebar columns, today marker, zoom levels (day/week/month/quarter), jump-to-start/end/date navigation and per-viewlet view options. * Editable bars: drag to move, resize handles for start/due date, drag on an unscheduled row to schedule it, optional confirm prompts and permission/conflict handling on commit. * Dependencies: FS/SS/FF/SF relations with lag, dependency editor and arrows, cascade shifting with cycle detection, and critical-path plus slack computation. A dependency shift raises a server-side notification for the affected assignees. * Visual polish: bar labels (left/inside/right), quick-info popover, milestone markers, deadline markers, non-working-day shading and keyboard-shortcut help. * Tier 2: undo/redo, saved views, bulk selection and bulk drag, auto-scheduling with manual pinning. * Tier 3: row virtualization for large projects. * Tier 4: mobile (read-only) layout, tree view with hierarchy breadcrumbs and a predecessor column. * Filter and search rework: inline filter chips with an overflow popover, an advanced search input with field prefixes routed to an Elasticsearch query_string branch, search scope and match-highlight view-option toggles, and a zero-hit empty state. * Bar coloring by status/priority/assignee/component/milestone, overdue and blocked overlays, and sub-issue progress fill. * Gantt toolbar export to PNG and to PDF. Both re-render the chart from the Gantt's own row model into a stand-alone SVG and rasterise that, so the output does not depend on the current scroll position or on rows that virtualization has not mounted; the PDF embeds the same raster as a real file download, not a browser print. Plus a fullscreen toggle. All of it lives in the Gantt toolbar only. * Responsive toolbar: the lifted toolbar measures the width it gets and collapses whole control tiers into a "…" popover, least important first, so Fullscreen and More-actions stay reachable from 390 px upwards. This needs one opt-in flag on the shared header component (`Header`/`SpaceHeader` `shrinkSearch`), which swaps which button group is the row's shrink target; it defaults to false, so no other header consumer changes behaviour. New runtime dependencies in plugins/tracker-resources, all MIT licensed: * @tanstack/svelte-virtual - row virtualization for sidebar and canvas * jspdf - wraps the exported chart raster into the PDF download Locales: en, de and ru carry the full set of new strings. The other locales are mostly unchanged and fall back to English at runtime; the few new keys they do define are still English placeholders. Translating those is left to native speakers. This consolidates the previously separate pull requests hcengineering#10853, hcengineering#10854, hcengineering#10855, hcengineering#10856, hcengineering#10857, hcengineering#10858, hcengineering#10859, hcengineering#10872 and hcengineering#10873 into a single change, as requested on hcengineering#10853, so the whole feature can be reviewed and tested in one place. The review feedback given on hcengineering#10853 is included. Signed-off-by: Michael Uray <michaeluray@users.noreply.github.com>

This consolidates the Gantt series — #10853, #10854, #10855, #10856, #10857, #10858, #10859, #10872 and #10873 — into a single pull request, as requested on #10853, so the whole feature can be reviewed and tested in one place. It contains the series plus the fixes made during consolidation.
What it adds
A Gantt viewlet for the Tracker: time-scale canvas with day/week/month/quarter zoom, sidebar columns, today marker and jump navigation; editable bars (drag, resize, schedule an unscheduled row) with confirm prompts and permission/conflict handling; FS/SS/FF/SF dependencies with lag, a dependency editor, cascade shifting with cycle detection, and critical-path plus slack; visual polish (bar labels, quick-info popover, milestone and deadline markers, non-working-day shading, shortcut help); undo/redo, saved views, bulk select and bulk drag, auto-scheduling with manual pinning; row virtualization for large projects; a read-only mobile layout, tree view with hierarchy breadcrumbs and a predecessor column; bar coloring by status/priority/assignee/component/milestone with overdue and blocked overlays and sub-issue progress fill; PNG and PDF export plus a fullscreen toggle, both confined to the Gantt toolbar. A dependency shift raises a server-side notification for the affected assignees; the trigger resolves the sender, the shifted issues and their metadata server-side and scopes everything to the request's own space.
Shared infrastructure changes (outside
plugins/tracker*)packages/ui— an opt-inshrinkSearchflag onHeader/SpaceHeaderthat swaps which button group is the header row's shrink target, so the Gantt toolbar can collapse control tiers into a "…" overflow popover instead of overflowing its row. Defaults tofalse; no other header consumer changes behaviour. Plus a few new icons.packages/theme— the two CSS rules that opt-in flag drives.plugins/view-resources,plugins/view,plugins/view-assets— the filter/search rework shared with List and Kanban: inline filter chips with an overflow popover, an advanced search input with field prefixes, search-scope and match-highlight view options, and a zero-hit empty state.foundations/server/packages/elastic— aquery_stringbranch used by the field-prefixed search; the existing non-field path is unchanged.packages/presentation,packages/importer,plugins/card-resources,models/server-tracker— small follow-on adjustments for the above.New runtime dependencies
Both in
plugins/tracker-resources, both MIT:@tanstack/svelte-virtual(row virtualization) andjspdf(PDF export). Export re-renders the chart from the data model into an SVG rather than capturing the DOM; the PDF is paginated into bounded pages so large charts stay within the browser canvas and jsPDF size limits.Locales
en,deandrucarry the full set of new strings, and a unit test enforces ICU placeholder parity across all locale files. Other locales fall back to English at runtime; the few new keys they define are still English placeholders, left to native speakers.Testing
Full CI is green on a fork mirror of this head —
build,svelte-check, unittest,formatting,docker-build,uitest,uitest-pg,uitest-workspaces,uitest-qms.Beyond CI, the feature went through several manual review rounds and a security pass. Those found defects that green unit tests did not — a toolbar that overflowed its own header row, dependency arrows capturing resize handles, a sidebar column left stale by a Svelte reactivity gap, a PDF export that exceeded the browser canvas and jsPDF page-size limits on large charts, the Gantt toolbar's fullscreen control sitting under the workbench mini-sidebar at phone widths, and a dependency-shift notification that trusted client-supplied metadata — all fixed here. E2E coverage asserts toolbar reachability at 1920, 1600 and 390 px with
toBeInViewport({ ratio: 1 })and real clicks (with an explicit overlap check at phone width), and covers the PNG and PDF downloads including a%PDF-magic-byte check.
