refactor(commands): Add IngestDisplay, resolve_project, and color-aware tables

Ingest:
- Introduce IngestDisplay struct with show_progress/show_text booleans
  to decouple progress bars from text output. Replaces the robot_mode
  bool parameter with explicit display control, enabling sync to show
  progress without duplicating summary text (progress_only mode).
- Use resolve_project() for --project filtering instead of LIKE queries,
  providing proper error messages for ambiguous or missing projects.

List:
- Add colored_cell() helper that checks console::colors_enabled() before
  applying comfy-table foreground colors, bridging the gap between the
  console and comfy-table crates for --color flag support.
- Use resolve_project() for project filtering (exact ID match).
- Improve since filter to return explicit errors instead of silently
  ignoring invalid values.
- Improve format_relative_time for proper singular/plural forms.

Search:
- Validate --after/--updated-after with explicit error messages.
- Handle optional title field (Option<String>) in HydratedRow.

Show:
- Use resolve_project() for project disambiguation.

Sync:
- Thread robot_mode via SyncOptions for IngestDisplay selection.
- Use IngestDisplay::progress_only() in interactive sync mode.

GenerateDocs:
- Use resolve_project() for --project filtering.
