feat: adaptive placement, ECharts capture chart, and study polish (#17)

* feat: adaptive placement, ECharts capture chart, and study polish

Seed progress with an adaptive diagnostic, render the mastery wheel in
ECharts with handbook-style hover emphasis, and tighten study/home copy.

* fix: hide default Core tier on capture slice list

Working tier is Core for every unlocked lifecycle unit at start, so the
label added no information. Keep it only once a unit reaches Advanced.

* fix: drop redundant Keep reading on study footer

The Continue/Finish button already says what to do next.

* feat: expand Fundamentals into a Prime capture glossary

Grow the Basics slice from a handful of cards to a FAR/govcon lexicon
a large-Prime capture teammate should know (NAICS, Alliant/SEWP/OASIS+,
IDIQ, OCI, CPARS, LPTA, etc.), and correct stale MPT/SAT figures.

* fix: keep summary score percent inside the ring

Widen the quiz-end donut hub and drop the label to text-3xl so 100%
no longer collides with the conic-gradient rim.

* fix: rename Fundamentals slice to Master the Basics

Align the capture-slice title with the chart's Basics label, and avoid
reintroducing a redundant Fundamentals difficulty badge on that unit.

* fix: correct placement Q index, gap study, and summary a11y

Keep adaptive "Q N" stable after answering, limit fundamentals gap
review to attempted misses, and expose the score percent to screen readers.
