Add work-log-tracker hook — lightweight session logging 🤖🤖🤖

[vidhartbhatia]

What this adds

A lightweight work-log-tracker hook that logs Copilot coding agent session start/end events to ~/.copilot-work-log/sessions.jsonl.

What it tracks

• Session start: timestamp, working directory, git repo name, git branch, PID
• Session end: timestamp, PID

No code or prompts are logged — only session metadata.

Why it's useful

Developers often lose track of what they worked on across repos and branches. This hook provides a zero-config, append-only log of session activity that can be queried later (e.g., "what repos did I touch last week?").

Files

File	Purpose
hooks.json	Hook event configuration (sessionStart + sessionEnd)
log-session-start.sh	Captures cwd, git repo/branch, timestamp
log-session-end.sh	Captures end timestamp
README.md	Documentation with installation, config, and privacy info

Relationship to existing work

• Complementary to What-I-Did-Copilot — that extension focuses on summarizing what the AI did; this hook focuses on when/where you worked
• For full-featured work tracking (manual entries, categories, git backup, markdown rendering), the README links to copilot-brag-sheet

Design choices

• No dependencies — pure bash, no jq required
• Privacy-first — only metadata logged, stored locally in ~/.copilot-work-log/
• Configurable — WORK_LOG_DIR env var to redirect output, SKIP_WORK_LOG=true to disable
• Follows the same patterns as existing hooks (session-logger, governance-audit)
