- parser: add GLMParser + parse_glm_tool_calls/strip_glm_tool_calls for GLM-5.2's
  <tool_call>name<arg_key>k</arg_key><arg_value>v</arg_value>...</tool_call> format
  (byte-compatible with colibri's own parser). Gated on the <arg_key> marker so a
  generic <tool_call>{json} from other families is never hijacked. Declared-type
  coercion keeps string args verbatim (no "12345"->int). Unclosed-box recovery for
  budget-truncated calls. Wired into family selection ('glm'/'colibri'), the
  model-agnostic ToolCallParser path, and both strip_tool_calls_from_content paths.
- manager: colibri no longer seizes the whole GPU like ds4. It pins only a
  configurable expert tier (CUDA_EXPERT_GB) and streams the rest, so it coexists and
  is evicted like any other model. VRAM footprint estimated from cuda_expert_gb
  (+overhead) until measured.

Verified: typed/untyped parse, strip, unclosed recovery, non-GLM gating, and the
by-name dispatcher all correct.
