Private-CLI installers silently rewrite global git config (HTTPS→SSH insteadOf), duplicated 4x

[PascalTemel]

Installing any of the four private Go CLIs silently mutates global git config:

git config --global url."git@github.com:".insteadOf "https://github.com/"

Present, copy-pasted, in all four installers: atl.js:90-104, n8n.js:100-116, esq.js:84-115, discord.js:73-104 (two execSync-based, two spawnSync-based — the duplication has already drifted stylistically).

Effects: every GitHub HTTPS remote on the machine is rewritten to SSH from then on — including unrelated personal repos and tooling that relies on HTTPS + credential manager — and a pre-existing, different insteadOf value is overwritten without warning.

Proposal

• Scope the rewrite to the single go install invocation instead of the machine: GIT_CONFIG_COUNT/GIT_CONFIG_KEY_0/GIT_CONFIG_VALUE_0 env vars (or GOFLAGS/GOPRIVATE + git -c equivalent) on the spawned process.
• If a global rewrite is genuinely desired, ask first and never overwrite an existing differing value.
• Extract the 4 copies into one shared helper while touching this.
