Godopu 0cb8d058cb feat(env): add .env.example template + scripts/generate-env.sh
.env.example: committable template (all 13 skill env vars commented with
defaults; secrets use replace_me, no plaintext). .gitignore already carves
it out via !.env.example.

scripts/generate-env.sh: creates .env from .env.example if absent, no-ops
if present, --force overwrites with a .env.bak backup. Placed under a new
top-level scripts/ dir so it is committable without touching skills/*.

Verified on -L claude-env2-test (create/no-op/force/bad-arg paths).

#!/usr/bin/env bash
# generate-env.sh — create a local .env from the committed .env.example template.
#
# Behaviour:
# - .env absent → copy .env.example to .env, print the path.
# - .env present → no-op (leaves your edits intact), exit 0.
# - .env present --force → overwrite .env from .env.example (backs up to .env.bak).
#
# Paths are resolved relative to this script (repo root = parent of scripts/),
# so it works regardless of the caller's cwd.
#
# Usage: scripts/generate-env.sh [--force] [-h|--help]
