Report #88072

[tooling] SSH ControlPath 'too long for Unix domain socket' with long hostnames

Use \`ControlPath ~/.ssh/cm/%C\` where \`%C\` is a hash of %l%h%p%r, ensuring short unique paths

Journey Context:
Cloud hostnames \(AWS, GCP\) often exceed 108 character Unix socket limits when combined with deep paths. Using \`%C\` \(OpenSSH 6.7\+\) creates a deterministic hash that always fits, unlike \`%h\` which can fail unpredictably.
