Add substring ID matching for all bd commands

- Enhanced ResolvePartialID to handle:
  - Bare hashes: 07b8c8 → bd-07b8c8
  - Prefix without hyphen: bd07b8c8 → bd-07b8c8
  - Full IDs: bd-07b8c8 (unchanged)
  - Substring matching: 07b → finds bd-07b8c8

- Added RPC support:
  - New OpResolveID operation
  - handleResolveID server handler
  - ResolveID client method

- Updated all commands to resolve IDs:
  - show, update, close, reopen
  - dep (add, remove, tree)
  - label (add, remove, list)

- Works in both daemon and direct modes

Fixes bd-0591c3
