feat: status bar format, tab titles with source, taller tabs, pill hover, source switch base fix

- Status bar: show StructName.field +0xOFFSET with dimmed offset suffix
- Status bar: sync font to global editor font (JetBrains Mono 10pt)
- Dock tab title: include active source name (StructName — source.exe)
- Dock tabs +10% height (28→31), pane tabs (24→26), workspace title (26→29)
- Footer pills (+1024, Trim, +10): add visual hover highlight via IND_HOVER_SPAN
- Fix source switch keeping old base address for plugin providers
