v1.6.17 — sipcode update command, session-pollution filter, opus 4.8

[Anuj7411]

Patch release. Quality-of-life fixes plus the missing update path.

Added

• sipcode update — prints your installed version + npm i -g sipcode@latest, or --run to upgrade in place. Zero network calls preserved (npm resolved as npm.cmd on Windows, no shell: true). README gained an "Updating Sipcode" section + FAQ.

Fixed

• Session-count pollution. Observer/telemetry plugin dirs (e.g. claude-mem) and empty zero-token sessions were inflating stats, today, why, forecast, trend. One machine: 1,446 → ~21 real sessions; today no longer shows "0 tokens" across empties. MCP tools inherit the fix via the shared discover.ts.
• estimate now shows opus 4.8 (was 4.7).
• Friendlier first run — stats on a fresh machine says "no Claude Code sessions found yet" instead of falsely claiming transcripts exist.

Release hygiene

• 1.6.16 → 1.6.17. CHANGELOG entry + repaired missing [1.6.16] link ref. README badge, llms.txt / llms-full.txt, and landing page (Hero + Footer, stale at v1.6.15) all bumped to 1.6.17 / 1,373 tests.

Verification

• 1,373 tests green (1,355 non-e2e + 18 e2e), lint + tsc clean, both privacy and no-shell-args guards pass with the new child_process use.
• Real-data smoke on-machine: estimate→4.8, stats 1446→21, today 0→3.6M tokens, why synthetic→real, empty-dir states friendly.
• Astro site rebuilds clean; rendered output shows 1.6.17 / 1,373.
