[Bug]: Bob integration cannot dispatch — build_exec_args() unimplemented

[temp-droid]

Bug Description

BobIntegration doesn't override build_exec_args(), so it inherits the IntegrationBase no-op returning None. Callers read None as "this CLI is unavailable", so every workflow command:/prompt: step targeting Bob fails, even with bob installed and on PATH.

Separately, BobIntegration extends IntegrationBase directly and inherits its hardcoded . separator, so build_command_invocation("speckit.specify") returns /speckit.specify while skills-mode projects install skills at .bob/skills/speckit-specify/. The class already computes the right separator in effective_invoke_separator().

Related: #2416 (build_exec_args audit — Bob isn't in its table, since it doesn't currently dispatch).

Steps to Reproduce

$ specify workflow run speckit -i spec="hello"

Running workflow: Full SDD Cycle (speckit)
Version: 1.0.0

  ▸ [specify] speckit.specify …

Status: failed
Run ID: a9de034e
Error: Cannot dispatch command 'speckit.specify': integration 'bob' CLI not found or not installed. Install the CLI tool or check
'specify integration list'.

bob is installed and on PATH:

$ bob -h
Usage: bob [options] [command]

Expected Behavior

The step dispatches to Bob, as it does for claude, codex, cursor-agent and goose.

Actual Behavior

The run fails at the first step with "CLI not found or not installed", which is misleading — the CLI is present and working.

Thanks — precise report. Both defects are real: BobIntegration inherits the IntegrationBase no-op build_exec_args() (returning None, which surfaces as the misleading "CLI not found"), and it uses the hardcoded . separator instead of its own effective_invoke_separator(). This is the same class as #4480 (agy) and another concrete instance of the systemic build_exec_args() audit in #2416 — Bob and agy are two integrations that silently don't dispatch. A PR wiring up build_exec_args() + using the computed separator, with a dispatch test, would be welcome.
