feat(mode): the access cap — plan mode composes with the sandbox instead of banning bash
A ModeDefinition may declare access: the widest sandbox access shell commands run under while the mode holds, on the SANDBOX_MODES ladder. The bash seam gains the resolution point to hang it on: BashExecutor. resolveMode(session) folds override ?? default and dispatches the new bash/resolve-mode waterfall; dsh-tool-bash consults it at both the stamping site and the escalation baseline; dsh-mode's clamp listener takes the ladder minimum per call. Two independent log folds compose at read time — the mode never writes the sandbox knob, so the two switch in any order and the knob re-emerges intact on exit. The built-in plan definition ships access: read-only with the bash trio allowlisted CONDITIONALLY: both policy layers admit bash/bash_output/ bash_kill only while a confining executor is mounted (an unconfinable shell cannot honor the cap), and a bash call carrying sandbox_permissions under a cap is denied at the gate — no widening mid-mode; the widened step belongs in the plan. examples/plan-acp-agent swaps bash-local for sandbox-local + bash-sandbox (workspace-write default, clamped read-only inside plan) plus the approval seam; the re-recorded plan-mode arc runs a real cat inside plan under the clamped sandbox, and modes-advertise now pins the sandbox-mode and approval config options. RFC amended to the landed shape (access cap section, orthogonality FAQ, deferred item resolved into effects self-declaration).
