pstack: route hardest tasks to claude-fable-5-thinking-max

[poteto]

Summary

• Adds a hardest-tasks tier to poteto-mode's Task-call defaults: cross-cutting design, gnarly concurrency, subtle algorithms, and vague intent go to claude-fable-5-thinking-max (mirrors the private setup's routing; deliberately no Sol tier here).
• Adds a matching hardest tasks: role line to the setup-pstack defaults rule so /setup-pstack users can override it.
• Bumps pstack to 0.10.2.

Test plan

• Only public model slugs referenced (Fable is a public Claude model)
• Grep confirms the new role line renders in the setup-pstack rule shape

Note

Low Risk
Skill and plugin metadata only; no application runtime or security-sensitive code paths change.

Overview
Adds a hardest-tasks model tier to pstack so the heaviest work (cross-cutting design, gnarly concurrency, subtle algorithms, vague intent) defaults to claude-fable-5-thinking-max on Task subagent calls, alongside the existing code and judgment defaults.

setup-pstack gains a matching hardest tasks: line in the generated pstack-models.mdc template so users can override that role. Plugin version is bumped to 0.10.2.

Hardest-tasks override never applies

Medium Severity · Logic Bug

poteto-mode hardcodes claude-fable-5-thinking-max for "hardest tasks", ignoring the configurable model defined via setup-pstack. Unlike other roles, this prevents user overrides in pstack-models.mdc from taking effect, forcing users to the hardcoded model even if they lack access or prefer another.
