feat(cli): status display/filtering, expanded --fields, and robot-docs --brief

Work item status integration across all CLI output:

Issue listing (lore list issues):
- New Status column appears when any issue has status data, with
  hex-color rendering using ANSI 256-color approximation
- New --status flag for case-insensitive filtering (OR logic for
  multiple values): lore issues --status "In progress" --status "To do"
- Status fields (name, category, color, icon_name, synced_at) in issue
  list query and JSON output with conditional serialization

Issue detail (lore show issue):
- Displays "Status: In progress (in_progress)" with color-coded output
  using ANSI 256-color approximation from hex color values
- Status fields included in robot mode JSON with ISO timestamps
- IssueRow, IssueDetail, IssueDetailJson all carry status columns

Robot mode field selection expanded to new commands:
- search: --fields with "minimal" preset (document_id, title, source_type, score)
- timeline: --fields with "minimal" preset (timestamp, type, entity_iid, detail)
- who: --fields with per-mode presets (expert_minimal, workload_minimal, etc.)
- robot-docs: new --brief flag strips response_schema from output (~60% smaller)
- strip_schemas() utility in robot.rs for --brief mode
- expand_fields_preset() extended for search, timeline, and all who modes

Robot-docs manifest updated with --status flag documentation, --fields
flags for search/timeline/who, fields_presets sections, and corrected
search response schema field names.

Note: replaces empty commit dcfd449 which lost staging during hook execution.
