v1.1.0 - per-turn cost chip

Adds the per-turn readout and fixes the dialog surface.

Added

• conversation.chat.assistant-actions chip: every completed turn shows what it cost, right beside the shipped usage badge. Click it for that turn's input / cache-hit / output split, model, billing instant and unit price.
• Shared popover shell for both entries (outside click, Escape, viewport clamping).

Fixed

• The bill dialog had no backdrop blur, so composer text bled through the translucent menu surface. It now wears the shipped stat-dialog material with a fallback blur value.
• Unloaded history was priced at "now", which re-billed a daytime conversation at the night rate when reopened. It now rides the blended rate the priced turns actually paid.

Docs

• Rendered docs/demo.png and docs/turn.png from the plugin's own stylesheet.
• CI runs the offline suite, a manifest check and a client.js parse.

v1.0.0 — live conversation spend

First public release.

Two readouts, one pricing engine:

• conversation.composer.dock cell — total spend of the open conversation, in CNY.
• conversation.chat.assistant-actions chip — what each completed turn cost, next to the shipped usage badge.

Every reply is priced at its own turn/start instant with the official DeepSeek table (including the 2026-08-17 peak/off-peak policy). Reopening a historical conversation keeps the historical prices; tokens with no per-turn record are estimated at the blended rate of priced turns and always carry a ≈.

Install: clone, then install.ps1 (Windows) or install.sh (macOS/Linux), restart dsh web, hard-refresh.
