chore: switch CLAUDE_EFFORT env var to --effort alias, add task tracking

install-plugins.sh: replace 'export CLAUDE_EFFORT=max' with
'alias claude="claude --effort max"' (cleaner, uses CLI flag).
Cleans up old env var from shell profile on re-run.

Also adds tasks/ tracking files and fixes trailing whitespace in CLAUDE.md.
