chore: fix claude hooks and add LSP tool env

- bash-guard: block awk (was missing from blocked commands)
- post-compact: replace fragile sed JSON escaping with jq -n --arg
- track-read: deduplicate entries before appending to .read-tracker
- settings: remove redundant Edit→require-read hook (built-in handles it)
- settings: add ENABLE_LSP_TOOL=1 for inline LSP diagnostics
