feat(achievements): share card render on unlocked badges (#19657)

* feat(achievements): share card render on unlocked badges

Adds a Share button to each unlocked achievement card that opens a
modal and renders a 1200x630 PNG share card client-side via Canvas2D
(no backend, no network, no new deps). Two actions: Download PNG and
Copy image to clipboard.

Card layout mirrors the in-dashboard visual language: tier-colored
glow, icon from the existing LUCIDE sprite set, achievement name,
tier badge pill, description, progress stat line, and a Hermes Agent
watermark. Sized for X/Twitter, Discord, LinkedIn, Bluesky link
previews.

Vendored on top of the upstream @PCinkusz bundle; the 'in-progress
scan banner' precedent already established this divergence pattern.
Manifest bumped 0.3.1 -> 0.4.0.

* feat(achievements): share-on-X as primary action on share dialog

Adds a 'Share on X' button as the primary action in the share dialog.
Opens https://x.com/intent/post with a pre-filled tweet referencing
the achievement name, tier, @NousResearch, and the Hermes docs URL.
Copy image and Download PNG become secondary actions: users who want
the badge attached can Copy image, paste into the X composer, post.

Primary button styled as X's signature black-on-white fill so the
action is unambiguous.

The screenshots use temporary demo tier data to show the full visual range. The plugin itself reads real local Hermes session history by default.
> **Update notice (2026-04-29):** If you installed this plugin before today, update to the latest version. The achievements scan path was refactored for much faster warm loads (snapshot cache + incremental checkpoint scan).
>
> **Share cards (2026-05-04, vendored in hermes-agent v0.4.0):** Unlocked achievement cards now have a "Share" button that renders a 1200×630 PNG share card (client-side canvas, no backend, no network) with Download + Copy-to-clipboard actions. Fits X/Twitter, Discord, LinkedIn, Bluesky link-preview dimensions.
