feat: add gstack-telemetry-log and gstack-analytics scripts
Local telemetry infrastructure for gstack usage tracking. gstack-telemetry-log appends JSONL events with skill name, duration, outcome, session ID, and platform info. Supports off/anonymous/community privacy tiers. gstack-analytics renders a personal usage dashboard from local data. Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

# gstack-telemetry-log — append a telemetry event to local JSONL
|
||||
#
|
||||
# Data flow:
|
||||
# preamble (start) ──▶ .pending marker
|
||||
# preamble (epilogue) ──▶ gstack-telemetry-log ──▶ skill-usage.jsonl
|
||||
# └──▶ gstack-telemetry-sync (bg)
|
||||
#
|
||||
# Usage:
|
||||
# gstack-telemetry-log --skill qa --duration 142 --outcome success \
|
||||
# --used-browse true --session-id "12345-1710756600"
|
||||
#
|
||||
# Env overrides (for testing):
|
||||
# GSTACK_STATE_DIR — override ~/.gstack state directory
|
||||
# GSTACK_DIR — override auto-detected gstack root
|
||||
#
|
||||
# NOTE: Uses set -uo pipefail (no -e) — telemetry must never exit non-zero
