feat(me): add lore me personal work dashboard command

Implement a personal work dashboard that shows everything relevant to the
configured GitLab user: open issues assigned to them, MRs they authored,
MRs they are reviewing, and a chronological activity feed.

Design decisions:
- Attention state computed from GitLab interaction data (comments, reviews)
  with no local state tracking -- purely derived from existing synced data
- Username resolution: --user flag > config.gitlab.username > actionable error
- Project scoping: --project (fuzzy) | --all | default_project | all
- Section filtering: --issues, --mrs, --activity (combinable, default = all)
- Activity feed controlled by --since (default 30d); work item sections
  always show all open items regardless of --since

Architecture (src/cli/commands/me/):
- types.rs: MeDashboard, MeSummary, AttentionState data types
- queries.rs: 4 SQL queries (open_issues, authored_mrs, reviewing_mrs,
  activity) using existing issue_assignees, mr_reviewers, notes tables
- render_human.rs: colored terminal output with attention state indicators
- render_robot.rs: {ok, data, meta} JSON envelope with field selection
- mod.rs: orchestration (resolve_username, resolve_project_scope, run_me)
- me_tests.rs: comprehensive unit tests covering all query paths

Config additions:
- New optional gitlab.username field in config.json
- Tests for config with/without username
- Existing test configs updated with username: None

CLI wiring:
- MeArgs struct with section filter, since, project, all, user, fields flags
- Autocorrect support for me command flags
- LoreRenderer::try_get() for safe renderer access in me module
- Robot mode field selection presets (me_items, me_activity)
- handle_me() in main.rs command dispatch

Also fixes duplicate assertions in surgical sync tests (removed 6
duplicate assert! lines that were copy-paste artifacts).
