refactor: eliminate ~400 no-explicit-any warnings across the workspace

Parallel subagent pass: four typescript-pro agents on non-overlapping scopes.

Patterns applied:
- catch (err: any) { ... err.message ... } → catch (err) { ... getErrorMessage(err) ... }
  using the new @fusion/core helper. Bare catch {} where the error was unused.
- SQLite row types: defined typed XxxRow interfaces per table and cast
  .all()/.get() results via `as unknown as XxxRow[]` (the double cast is
  required because better-sqlite3 returns Record<string, SQLOutputValue>).
- rowToX(row: any) converters: typed argument with the matching row interface.
- Dynamic settings key writes: (settings as Record<string, unknown>)[key].
- React event handlers and setState callbacks: inferred types or concrete
  React.{Mouse,Change,Form}Event<...> where needed.
- pi-claude-cli: local PiMessage / PiContext duck types to avoid re-typing
  pi-ai concrete shapes; typed Claude stream event message fields.

72 files changed, ~400 anys eliminated. Typecheck passes across the workspace.
