Socket v10.0.3

Changes

Replaces Socket's Python and shell repository automation with managed F#
scripts and canonical just commands from repository-skills 10.0.2.
Makes just docs-check and just docs-apply the only documentation commands;
both always process README, CONTRIBUTING, AGENTS, and ROADMAP together.
Adds agent-plugin-skills:maintain-agent-plugins with managed FSX assets,
exactly just plugins-check and just plugins-apply, fixed Socket publisher
policy, complete-manifest reconciliation, and repository-skills integration.
Narrows agent-portability-skills to cross-host protocols and adapters,
keeps agent-system behavior in agent-engineering-skills, and makes
AgentDeck's runtime-hook versus package-maintenance boundary explicit.
Aligns Socket plugin manifests with current plugin metadata shape, including
fixed publisher/license fields, default hook discovery, and no more than
three starter prompts.
Consolidates validation into one root integration/E2E test and makes root
skill export synchronization discover newly declared managed skills.

Removes the obsolete plugin bootstrap and guidance-sync skills and their
stale exports. Use agent-plugin-skills:maintain-agent-plugins instead.
Removes SwiftASB Skills and the deleted Python bootstrap, project-creation,
FastAPI, FastMCP, and agent-service skill surfaces.
Removes nested child tests/evals and legacy Python or shell repository
automation. Socket validation now runs only from the repository root.
Removes per-document documentation commands and customization profiles.

Refresh repository maintenance from repository-skills 10.0.2 or later, then
run just repo-sync.
Replace old plugin bootstrap or guidance-sync invocations with
$maintain-agent-plugins; use just plugins-apply for full reconciliation
and just plugins-check for read-only validation.
Replace nested child validation commands with just repo-validate and
just test at the Socket root.
