CV optimization and role-specific variants

[FARADTechnologies]

Context

Two things depend on the CV: the quality of applications, and the profile spec the LLM
judge matches against (jobbot/judge.py::PROFILE_SPEC). Improving the CV therefore
improves matching as a side effect.

Proposal

1. Produce one strong, general-purpose CV
2. Derive role-specific variants (e.g. software/data, robotics/embedded, technical-content)
3. Regenerate PROFILE_SPEC from the optimized CV so judging reflects it

Acceptance criteria

• Base CV reviewed and tightened
• At least two role variants
• Judge profile spec regenerated and match quality re-checked
