Round 1: Fix updateCommandRow offset, structTypeName undo, changeNodeKind
macro, shift-click kCommandRowId leak, type filter byte-vs-column bug.
Round 2: Move kFooterIdBit to core.h, add RcxEditor destructor for cursor
cleanup, defer refresh during batch ops, use newline separator in type
picker, narrow selection on double-click edit, clear hover on keyboard
scroll, guard 0x prefix from deletion, cap array count at 100k.
Collapse Provider interface from 9 virtual methods to 2 (read + size),
move providers to src/providers/, add name()/kind()/getSymbol() virtuals.
Replace FileProvider with BufferProvider, add ProcessProvider (Win32)
with module-based symbol resolution, wire ProcessPicker dialog, and
integrate getSymbol into pointer display and command row.
- Fix isReadable overflow for large addresses
- Guard deferred showSourcePicker/showTypeAutocomplete against stale edits
- 7/7 tests pass including 3 new provider test suites
