practice: the chain table — every reasoning chain in one selectable overlay (owner-approved plan, 2026-09-29)

- core formatChainLine: names + arrow one-liner, singleton marker, pure
- graph-view Chains button (chrome row, empty-graph hidden) opens the
  overlay: fuzzy search (names/aliases/statements), collapsible chain →
  member → statement rows, birth-session + created columns, no
  understanding-levels column
- pinned Selected section derives the agents' actual input live
  (chainsForSelection over the selection; premise without its
  conclusion shows as the singleton it becomes)
- Generate opens the creation dialog in CUSTOM mode: selection summary
  + dated default title, posts {nodeIds, params, note}; cluster mode
  untouched on /practice
- live-verified on the owner's dev server: 219 chains, derived preview,
  search-never-filters-Selected, dialog handoff (selection pass-through
  bug caught + fixed en route), Esc/backdrop dismiss, zero writes
- practice UI files re-normalized to tabs (my earlier prettier runs had
  drifted them to the 2-space default; whitespace-only)

17 render/unit pins added; gates: tsc 0, 1174/1174, lint 0, build 0

/**
* THE CHAIN TABLE (chains overlay, owner-approved plan 2026-09-29): every
* reasoning chain of the graph in one selectable table — the graph view's
* practice entry for FREE-FORM selections, complementing the cluster
* picker (which stays the /practice page's only creation mode). Read-only
* toward the graph: it renders the snapshot it is handed, selects node
* ids, and hands the selection to the practice dialog's CUSTOM mode.
*
* MOUNT IDIOM (the session-overlay precedent, session-overlay.tsx): the
* overlay is ABSOLUTE INSIDE the graph area (never a body portal) —
* inset-0, z-40, bg-background/80 + backdrop blur — so the app chrome
* (drag bar, sidebar) stays sharp and reachable; Esc and backdrop clicks
* dismiss.
*
* STRUCTURE: a fuzzy search box (names, aliases, statements — core's
* fuzzyScore) at the very top filters the chain list only; the SELECTED
* section is pinned beneath it, never filtered — N propositions → M
* chains via chainsForSelection over the selection (the agents' ACTUAL
* input: a selected premise without its conclusion shows as the singleton
* it becomes). Chain rows (the core formatter's name line) expand to
* indented member proposition rows; each member expands its full
* statement inline. Columns: checkbox | chain/proposition tree | birth
* session(s) | created. NO understanding-levels column (explicitly not
* built — no dead markup).
*
* Named neutrally (ChainTable, not Practice*) — the table is a
* graph-surface; only the Generate handoff knows about practice.
