Kayos cb1d8c2c54 clients/bash: v0.2 multi-turn session subcommands
- cf session new / turn / close / list / get
- --json flag mirrors v0.1 convention
- close is idempotent (exit 0 on already-closed)
- Bearer hygiene preserved (regression guard test)
- tests/test_session.sh: ~18 tests, 44 assertions
- README "Sessions (v0.2)" section

v0.1 subcommands unchanged.

# cf — bash CLI for clawdforge
#
# Usage:
# cf healthz
# cf run "<prompt>" [--model sonnet] [--system "..."] [--timeout 60] [--files token1,token2]
# cf run - # read prompt from stdin (any size)
# cf upload <path> [--ttl 3600]
# cf admin token-mint <name> [--ip-cidrs cidr1,cidr2]
# cf admin token-list
# cf admin token-revoke <name>
#
# Sessions (v0.2 — multi-turn):
# cf session new [--agent claude] [--meta '{"k":"v"}'] [--json]
# cf session turn <id> "<prompt|->" [--files tok1,tok2] [--timeout 120] [--json] [--trace path]
# cf session get <id> [--json]
# cf session list [--include-closed] [--json]
# cf session close <id> [--json]
#
# Sessions don't autoclose — call `cf session close <id>` when you're done.
# Server-side TTL is 1h idle by default.
#
# Configuration (env or ~/.config/clawdforge/cf.env, env wins):
# CLAWDFORGE_URL — default http://192.168.0.5:8800
# CLAWDFORGE_TOKEN — required for /run + /files + /sessions
# CLAWDFORGE_ADMIN_TOKEN — required for admin/* subcommands
#
# The cf.env file MUST have permissions 0600 or 0400 and be owned by you,
# or cf will refuse to source it.
#
# Output:
# - successful command → response JSON to stdout (pipe to jq freely)
# - errors → message to stderr, non-zero exit code
#
# Exit codes:
# 0 ok
# 1 generic error / curl failure
# 2 bad usage
# 3 missing token
# 4 HTTP 4xx (auth / not-found / bad-request)
# 5 HTTP 5xx (server / claude failure)
# --- end help ---
