pi-linkup: v0.10.0

Minor Changes

• 42481a6: refactor: per-extension entries to fix duplicate command registration

  Replace monolithic entry with 4 separate extension entries:

  • web-search, web-answer, web-fetch (tools)
  • command-balance (shows API credits)

  Delete broken singleton pattern from setup.ts that caused commands to appear 3x in palette (GitHub #24). Pi loads each extension in separate module context, so module-level guards failed. Each entry now calls ensureLinkupReady() independently.

  Also remove obsolete command-settings (guidance settings no longer exist; tools declare their own promptGuidelines).
