Strips reviewer-attribution markers ('review-N <date>') from source-code
comments. Comments are kept and rephrased as 'review note' so the noted
constraint or hidden invariant survives, only the internal attribution
is dropped.

Resolve four pre-existing eslint errors that block the CI formatting job:
- GanttCanvas.svelte: split the milestone null-guard into nested {#if}
blocks (prefer-optional-chain) — a naive optional chain would bypass
the strict null check when range is null.
- GanttCanvas.svelte / GanttSidebar.svelte: convert void-returning
short-circuit handlers to block-body arrows (no-confusing-void-expression).
- layout.test.ts: drop the non-null assertion in favour of optional
chaining on the assertion (no-non-null-assertion).

The drag-controller reducer only accepted mousedown-bar from hover-bar state, but no DOM event ever transitioned idle → hover-bar (we never wired the mouseenter-bar event from GanttBar to the reducer). The hover state was dead code, and the first mousedown on a freshly-rendered bar was silently dropped — Playwright integration test surfaced this. Fix: reduceFromIdle accepts mousedown-bar directly with the same edge-discriminator logic as reduceFromHover. Real users always go through hover-bar first (mouseenter fires before mousedown), but synthetic event dispatch and re-render edge cases can skip it. Adds 2 tests: - mousedown-bar from idle → dragging-body - mousedown-bar (edge=left) from idle → resizing-left Signed-off-by: Michael Uray <michaeluray@users.noreply.github.com>
…sion 1. Context menu is too tall (~19 entries from auto-resolved Huly actions). Restructured via includedActions allow-list to 9 curated entries that make sense for a Gantt bar: - Open (Edit issue) - Status / Priority / Assignee (existing actionPopup submenus, ›) - Set start date / Set due date - Copy issue ID / URL - Duplicate / Delete Component, Milestone, Labels, SubIssue, SetParent, Relations, Move-to-project and time-report stay accessible from the standard List/Kanban menu but are hidden from Gantt's right-click. 2. Unscheduled-drag-grip in the sidebar shared pointerdown with the canvas pan handler. Pan would start before the grip's mousedown|stopPropagation fired, swallowing the drag. Extended onCanvasPanStart exclusion: now also bails on .sidebar-cell, .drag-grip, .resize-handle. The grip's pointerdown no longer triggers a stray pan.

…Phase 3a Pure-logic computeVisibleRowRange returns the visible row index range plus top/bottom spacer heights for a uniform-row-height virtual list. Stages the data path the sidebar renderer will adopt in a follow-up to handle 1000+ rows under the new column system without breaking the canvas scroll coupling. 10 unit tests cover edge cases (empty list, top/bottom edges, overflow, rubber-band scroll, zero rowHeight).

…s virtualization as the virtualization library (~50 KB minified, Apache-2.0). Headless virtualizer will drive a single Y-viewport manager that the Gantt sidebar, canvas, and dependency-arrow layer all subscribe to so the three layers stay scroll-synced without re-implementing fixed-row-height math in each component.

…rtualization Pure-logic Y-axis virtualization surface (computeYViewport, rowIndexToY, yToRowIndex, sliceVisibleRows) — mirrors the runtime virtualizer's decisions so the sidebar + canvas + dependency layer can be tested deterministically without a browser.

… y-viewport Pure-logic classifyArrowVisibility() + clippedEndpointPx() helpers tell the dependency layer which arrows to render in full, which to clip at the viewport edge with an off-screen indicator, and which to cull. Both endpoints on the same off-edge side → none. Endpoints straddling opposite edges → both-off (arrow path still crosses the viewport). Single-pixel overlap with bounds counts as visible.

Synthetic sweep over 100 / 50 scroll positions on a generated 1000 / 5000 row dataset. Budgets are loose (500 ms / 1500 ms) so the test doesn't flake under rush parallel test execution; actual runtime is single-digit ms on modern CPUs.

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 (via the browser print dialog) and a fullscreen toggle. Both live in the Gantt toolbar only. New runtime dependencies in plugins/tracker-resources, all MIT licensed: * @tanstack/svelte-virtual - row virtualization for sidebar and canvas * html2canvas - rasterizes the Gantt SVG for the PNG export * jspdf - wraps that raster into the PDF export 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.

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.

Summary
Vertical virtualization for the Gantt y-axis: only the rows within (or near) the visible viewport are mounted, and the dependency-arrow layer skips arrows whose endpoints both lie outside the viewport. Uses
@tanstack/svelte-virtualas the foundation. Designed so projects with thousands of issues stay smooth — Jest performance gates assert that the y-viewport manager scales to 1 000 and 5 000 rows.What's in this PR (+7 incremental commits)
