0.8.0-beta.1 — UX polish (stages A+B)

Pre-release of the UX polish milestone (stages A + B of the UI polish spec). Settings from older versions migrate automatically on the first load. Install via BRAT (add this repo, enable beta versions) or drop main.js / manifest.json / styles.css into .obsidian/plugins/graph-insight/.

Added

• Tasks… menu: six canned jobs (explore a topic, forgotten important notes, orphans, broken links, recent activity, vault structure), each also a hotkey-able command. Diagnostic tasks clear the hard filter with Undo in the notice.
• Visible search states: live "Highlighted: N" while typing, "Shown: N of M" plus a removable chip after Enter, an Enter hint until first use, "Indexing…" for content: scans, and parse diagnostics that never silently break the filter. Escape closes suggestions first, clears second.
• Tool status line under the toolbar with Path start/end stages and Follow / Side pane badges (aria-live).
• Breadcrumb history in Focus and Explore — Backspace, the Back button and breadcrumb clicks walk one shared 50-step trail; narrow panes collapse the middle; deleted notes are disabled and removable.
• Topic map export to Markdown from Focus, Explore, a lasso selection or a single visible cluster: overview, central notes, BFS levels with directions, links inside the map. Conflicts offer Overwrite / Create a copy / Cancel.
• Saved filter manager: explicit names, Apply / Edit / Duplicate / Delete, recently-used-first ordering, validation before saving.
• "Restore recommended values" for physics with a change summary and Undo.
• Three-step intro tour (Next / Back / Skip / Don't show again), reopenable from Settings and the command palette.
• Responsive floating UI: full / compact / minimal modes driven by the pane's own width, with an overflow menu for hidden actions.

Changed

• Double-click enters Focus mode and never opens the note; single clicks wait one 350 ms double-click window, so Hide/Pin/Path can't fire on the first half of a double-click.
• The layout rule is persisted and rides along in view presets.
• Camera widget: X/Y sliders removed; Fit whole graph and the new deterministic Reset camera are separate buttons.
• The Physics section's collapsed state persists.
