* unsloth start: add --resume to persist and reopen agent sessions
`unsloth start <agent>` launches a coding agent whose home is a throwaway
temp dir wiped on exit, so codex/openclaw/hermes/pi (which relocate their
whole home there) cannot resume a conversation after you quit. opencode and
claude keep their session data in a fixed user dir, so they already resume.
Add an opt-in --resume/--no-resume flag: it routes the launch to the stable
Unsloth agents dir (the same one --no-launch already uses) so the session
survives the exit, never touching the user's own ~/.<agent>. A bare --resume
also reopens the last conversation via the agent's native flag (codex
`resume --last`, opencode/claude/pi `--continue`). The default is unchanged:
a plain launch still uses a temp dir and persists nothing.
Add a dispatch-only `resume` job to the Local Agent Guides CI that drives the
real launch path and asserts the split: codex/pi are wiped without --resume
and persist with it, while opencode/claude persist either way.

* unsloth start: rename --resume to --persist
The session flag collided with agents' own resume flags. `unsloth start
claude --resume <id>` used to forward `--resume <id>` straight to Claude
(which keeps its history in ~/.claude regardless), so a boolean --resume on
unsloth start would have swallowed the session id and turned it into a stray
prompt. Name the persistence flag --persist instead, so every agent's native
resume flag (claude --resume <id>, codex resume, opencode --continue, ...)
still passes through untouched. Behavior is otherwise identical: --persist
keeps a launched agent's session under the Unsloth agents dir, and a bare
--persist reopens the last conversation.
Add a regression test that `--resume <id>` passes through verbatim, and in the
CI resume experiment skip the redundant second pass for opencode/claude (they
persist either way, and a second CPU turn only risks a timeout).
* unsloth start: correct --persist help and drop the buggy auto-resume
Reword the --persist help to be accurate: claude and opencode keep sessions in
the user's own stores and resume regardless, so --persist only stabilizes the
otherwise-ephemeral relocated home of codex/openclaw/hermes/pi. Drop the
bare-launch auto-append of native resume tokens: it errored on a first launch
with no prior session, and was inconsistent between launch and no-launch.
--persist now only keeps the session dir; resume via the agent's own command
(e.g. `unsloth start codex --persist resume`), which now finds it.
In the CI resume experiment, fail the pass when the launched turn exits
non-zero, so a write-then-error is not misread as PERSISTED.
