Rewrite README for the FeedBack rename and current feature set

Rewrite README for the FeedBack rename and current feature set

Tiny, standalone docs cleanup — no code touched, can be reviewed/merged
independently of any other open branch/PR in any order.

Why

The README still read as the pre-rename slopsmith-plugin-staffview:

• Title/org referenced "Slopsmith" throughout.
• A "Requires: a Slopsmith build with the sloppak notation schema... the
  feat/notation-schema-v1 branch" callout pointing at a branch that's long
  since merged.
• A "Playback mode" section describing the alphaSynth transport pill,
  which was dropped from the plugin back in Drop alphaSynth playback; fix empty-measure rests and click-to-seek #4.

What changed

Rewrote it to describe what the plugin actually does today:

• Corrected org/product references (FeedBack, not Slopsmith).
• The full options pill: NOTE DETECTION, STUDY, HAND, MIDI, LAYOUT, ZOOM.
• MIDI input scoring via the core midi-input / note-detection domains.
• Miss-dot overlay, the core stats/HUD bridge (+ HUD repositioning).
• Monitor synth (WebAudioFont).
• Study mode, explicitly noted as unscored practice (doesn't feed the
  live HUD / song_stats).
• Note explorer, OGG loop.
• Added a ## Tests section (the plugin now has a full node:test suite —
  there wasn't one before).
• Kept the original origin-story credit line.

Supersedes #1 — that PR fixes one URL's casing (got-feedback/feedback → got-feedback/feedBack); this rewrite includes that same fix (using the properly-cased org, got-feedBack) plus the rest of the file (title, org/product prose, the dead alphaSynth "Playback mode" section, current feature set). Once this merges, #1 should be closed rather than rebased — there's nothing left in it to land.

Code review

Docs-only PR — verified README claims against the code.

Verified accurate:

• npm test exists (node --test tests/*.test.js)
• ±100ms hit window matches screen.js:70
• Feature list (miss-dots, study mode, monitor synth, note explorer, OGG loop) matches the current code
• Playback-mode removal is correct — alphaSynth was dropped in Drop alphaSynth playback; fix empty-measure rests and click-to-seek #4

Minor (non-blocking):

• "curated into the org for the piano/keys epic" drops the old issue ref (slopsmith#828); fine if those refs are dead post-rename, just noting the link is lost.
• The Tests section says "host-integration helpers", but the suite also covers MIDI message parsing (tests/midi.test.js) — slightly narrow wording, cosmetic.

Note: the copyright line removal was flagged and explicitly accepted by the maintainer.

LGTM.
