feat(me): improve dashboard rendering with dynamic layout and table-based activity

Overhaul the `lore me` human-mode renderer for better terminal adaptation
and visual clarity:

Layout:
- Add terminal_width() detection (COLUMNS env -> stderr ioctl -> 80 fallback)
- Replace hardcoded column widths with dynamic title_width() that adapts to
  terminal size, clamped to [20, 80]
- Section dividers now span the full terminal width

Activity feed:
- Replace manual println! formatting with Table-based rendering for proper
  column alignment across variable-width content
- Split event_badge() into activity_badge_label() + activity_badge_style()
  for table cell compatibility
- Add system_event_style() (#555555 dark gray) to visually suppress
  non-note events (label, assign, status, milestone, review changes)
- Own actions use dim styling; others' notes render at full color

MR display:
- Add humanize_merge_status() to convert GitLab API values like
  "not_approved" -> "needs approval", "ci_must_pass" -> "CI pending"

Table infrastructure (render.rs):
- Add Table::columns() for headerless tables
- Add Table::indent() for row-level indentation
- Add truncate_pad() for fixed-width cell formatting
- Table::render() now supports headerless mode (no separator line)

Other:
- Default activity lookback changed from 30d to 1d (more useful default)
- Robot-docs schema added for `me` command
- AGENTS.md and CLAUDE.md updated with `lore me` examples
