refactor(cli): migrate all command modules from console::style to Theme

Replace all console::style() calls in command modules with the centralized
Theme API and render:: utility functions. This ensures consistent color
behavior across the entire CLI, proper NO_COLOR/--color never support via
the LoreRenderer singleton, and eliminates duplicated formatting code.

Changes per module:

- count.rs: Theme for table headers, render::format_number replacing local
  duplicate. Removed local format_number implementation.
- doctor.rs: Theme::success/warning/error for check status symbols and
  messages. Unicode escapes for check/warning/cross symbols.
- drift.rs: Theme::bold/error/success for drift detection headers and
  status messages.
- embed.rs: Compact output format — headline with count, zero-suppressed
  detail lines, 'nothing to embed' short-circuit for no-op runs.
- generate_docs.rs: Same compact pattern — headline + detail + hint for
  next step. No-op short-circuit when regenerated==0.
- ingest.rs: Theme for project summaries, sync status, dry-run preview.
  All console::style -> Theme replacements.
- list.rs: Replace comfy-table with render::LoreTable for issue/MR listing.
  Remove local colored_cell, colored_cell_hex, format_relative_time,
  truncate_with_ellipsis, and format_labels (all moved to render.rs).
- list_tests.rs: Update test assertions to use render:: functions.
- search.rs: Add render_snippet() for FTS5 <mark> tag highlighting via
  Theme::bold().underline(). Compact result layout with type badges.
- show.rs: Theme for entity detail views, delegate format_date and
  wrap_text to render module.
- stats.rs: Section-based layout using render::section_divider. Compact
  middle-dot format for document counts. Color-coded embedding coverage
  percentage (green >=95%, yellow >=50%, red <50%).
- sync.rs: Compact sync summary — headline with counts and elapsed time,
  zero-suppressed detail lines, visually prominent error-only section.
- sync_status.rs: Theme for run history headers, removed local
  format_number duplicate.
- timeline.rs: Theme for headers/footers, render:: for date/truncate,
  standard format! padding replacing console::pad_str.
- who.rs: Theme for all expert/workload/active/overlap/review output
  modes, render:: for relative time and truncation.
