Decompose the 207-line launch() into six named helpers: _allocate_resources,
_mint_certs, _start_bundle, _discover_urls, _launch_vm, _init_vm. Each has
explicit inputs/outputs and is independently testable.
Replace time.sleep(1.5) with smolvm.wait_exec_ready(), which polls
`machine exec true` with exponential backoff. Exits as soon as the exec
channel is ready; dies loudly with a timeout message instead of silently
leaving the VM in an unknown state.
File-lock loopback_alias.allocate() with fcntl.flock(LOCK_EX) so concurrent
bottle launches can't race on docker state and claim the same alias.
Add `provisioned_env: dict[str, str]` to `AgentProvisionPlan`. When
`forward_host_credentials=True`, `agent_provision_plan` reads the host
Codex access token at prepare time and stores it under
`CODEX_HOST_CREDENTIAL_TOKEN_REF`. Both backends merge `provisioned_env`
over `os.environ` before calling `egress_resolve_token_values`, so the
token slot resolves like any other manifest-declared token ref.
Removes `egress_resolve_token_values_with_provider` and the sentinel
`continue` skip from `egress_resolve_token_values`. The function is now
fully generic — it neither knows nor cares about provider identity.
Extract egress_resolve_token_values_with_provider into bot_bottle/egress.py.
Both docker and smolmachines launch paths now call the shared function
instead of duplicating the forward_host_credentials / CODEX_HOST_CREDENTIAL_TOKEN_REF
resolution block.
Also fixes the host_env: object annotation on smolmachines._resolve_token_env
to the correct dict[str, str].
Closes#118.
