Claude Code handover v1.4.1

• The guard's limit is now 35% of HANDOVER_CONTEXT_WINDOW (still 350,000 tokens with the default 1,000,000), so the window setting moves the limit instead of only the percentage shown. HANDOVER_CONTEXT_LIMIT still wins when it is set. A window that is not a positive number counts as unset.
• The installed /recall skill finds the script and the transcripts from its own folder, ${CLAUDE_SKILL_DIR}, which Claude Code fills in before the model reads the skill. It used to name ~/.claude, so with CLAUDE_CONFIG_DIR set it missed the copy init installs; now it follows it, and the command keeps nothing for the shell to expand, so Bash(node:*) covers it as before.
• scripts/selftest.mjs --replay follows CLAUDE_CONFIG_DIR, HANDOVER_PROJECTS_DIR and HANDOVER_DATA_DIR like recall does, instead of always reading ~/.claude.
• init keeps a claude-token-rules.md you edited as claude-token-rules.md.bak-YYYYMMDD before it replaces the card, and reports the backup; a card it wrote for another model list is replaced without one.
• scripts/usage-report.mjs and scripts/cache-report.mjs read the transcripts of $CLAUDE_CONFIG_DIR when it is set, as recall does (--root still wins), and the cache report names its 55-minute threshold in its headings. The threshold is unchanged.
• Documentation matched to the code. The guard asks once, at the end of a turn above the limit, when HANDOVER.md is older than 30 minutes; it does not hold the turn open until the handover is written, and 35% is a share of the window. Also corrected: SECURITY.md (what reaches Claude, what uninstall keeps), the setup prompt (backup name, a longer cleanupPeriodDays, rules card rows, git pull on a plain copy), the README (recall index, saved effort levels, --no-hooks, model ids, next-day sessions, the stress test, model combinations, CI on Node 18) and CONTRIBUTING (a throwaway config folder that stays set, the prompt route, "every job").
• Tests for each of these, and for all 15 combinations of the four models.

See the README to set it up, and CHANGELOG.md for every version.
