Explain each reading, on hover and in a details view

[sachinsachdeva]

The status bar could only ever show one number per metric, with no room to say what it meant. This adds two ways to ask, and bumps the extension to 2.0.0.

Hover

Hovering a reading opens a markdown panel for that metric alone: the user/system split and per-core load bars behind the CPU percentage, cached and swap memory behind the memory fraction, the GPU's name and core count, battery health and cycle count, and used/free/total for every volume regardless of which single figure disk.format picks.

That per-metric split is why the readings are now five status bar entries rather than one — an entry is the unit VS Code attaches a hover to. Each can now be hidden on its own, and a group whose metrics are all off or unavailable disappears rather than sitting empty.

Click

Clicking opens a details view docked in the panel beside Terminal and Problems, which stays put while it is read. It closes by its title bar ✕, by clicking the same reading again, or from the palette; clicking a different reading moves the outline instead. The panel carries no System Vitals tab until one is asked for.

Breaking changes (hence 2.0.0)

Three things change without being asked to. No setting was removed or renamed, so existing configuration carries over untouched.

• Status bar goes from one entry to five; anyone who hid or repositioned it must redo that, and narrow windows may drop the lower-priority entries.
• updatefrequencyms defaults to 10s rather than 2s. VS Code redraws an open hover the instant its content changes, so one interval now governs the reading and its details together — they can never show different samples.
• Minimum VS Code goes 1.53 → 1.74, for markdown status bar tooltips.

Notes

• The hover is deliberately untrusted markdown: the click carries the only command worth offering, so no command link has to survive a hostile volume name. Every system-supplied string is still escaped.
• The details view's document loads nothing from anywhere (default-src 'none', per-view nonce) and writes every figure with textContent.
• Each metric is sampled once per update and feeds the status bar, its hover and the view alike.

48 tests pass; VSIX verified to bundle systeminformation and ship no tests or source maps.
