Add jsweep daily workflow for automated JavaScript cleanup

[Copilot]

Creates a scheduled agent that cleans one .cjs file per day from pkg/workflow/js/, focusing on modernization and removing code bloat.

Workflow Configuration

• Schedule: Daily (fuzzy scheduled)
• Engine: Copilot (default model)
• Tools: serena (TypeScript/JavaScript), github (read-only), edit, bash, cache-memory
• Scope: 154 non-test .cjs files in rotation

Agent Capabilities

The agent is an expert at:

• Context detection (github-script vs Node.js execution)
• Removing unnecessary try/catch blocks that don't handle control flow
• Applying ES6+ patterns: spread operators, map, reduce, arrow functions, optional chaining (?.)
• Increasing test coverage during cleanup
• Logic preservation while improving clarity
• Static code analysis using serena for better code understanding

Pull Request Automation

• Title prefix: [jsweep]
• Labels: unbloat, automation
• Non-draft PRs for immediate review
• Tracking via jsweep-daily tracker-id

Example Cleanup Patterns

// Remove unnecessary try/catch
- try { return await op(); } catch (e) { throw e; }
+ return await op();

// Modern JavaScript
- const items = []; for (let i = 0; i < arr.length; i++) items.push(arr[i].name);
+ const items = arr.map(item => item.name);

- const value = obj && obj.prop && obj.prop.value;
+ const value = obj?.prop?.value;

Cache-memory tracks cleaned files with timestamps to ensure systematic coverage without duplication.

Original prompt

Create a JavaScript unbloater daily agent that focuses on cleaning one .cjs file per day. Call it jsweep"

The agent is an expert at creating and maintaining solid, simple JavaScript (commonjs)

• use cache and timestamps to find the next .cjs to cleanup

Principals:

• determines if the file runs in github-script context or node.js context. Expert in actions/github-script
• always increase testing when cleaning
• remove try/catch unless the exception is handled with control flow. Let errors bubble up otherwise.
• leverage spread operators, map, reduce, lambda syntax, ?. operator
• do not change logic, just cleaner leaner code

Provides a pull request with label "unbloat" and title "[jsweep] "
