Add boolean value support for safe-outputs.body configuration

[Copilot]

The update-issue safe-output only supported key-presence semantics (body: enables updates). This adds explicit boolean control: body: true enables, body: false disables.

Changes

Schema & Parser

• JSON schema accepts type: ["boolean", "null"] for body field
• Parser switched from FieldParsingKeyExistence to FieldParsingBoolValue mode
• Config generation uses AddBoolPtrOrDefault with true default

Handler Validation

• JavaScript handler checks config.allow_body before processing body updates
• Logs warning when body update is attempted but blocked
• Other fields (title, status, labels) remain updatable regardless of body setting

Behavior

safe-outputs:
  update-issue:
    body: true    # Explicit enable
    body: false   # Explicit disable (blocks updates, logs warning)
    body:         # Null value → true (backward compat)
    # omitted     # Missing → true (default)

Backward Compatibility

Existing workflows unchanged:

• body: (null) → allow_body: true (maintained key-existence semantics)
• Missing field → allow_body: true (safe default)

Original prompt

Add support for safe-outputs.body: true as a way to allow updating the issue body. Update JSON schema and parser.

Category: feature | Risk: medium | Priority: 32/100

Scores Breakdown

• Impact: 25/50 - New feature for safe-outputs body update functionality, medium impact on workflow capabilities
• Urgency: 2/30 - WIP status, very new (< 1 hour old), no blocking issues or priority labels
• Quality: 5/20 - CI pending, WIP status indicates incomplete implementation

📋 Recommended Action: defer

Explanation: This WIP PR needs completion before review. The feature adds body update support to safe-outputs which is valuable, but should be revisited when the [WIP] tag is removed and CI validation passes.

Next Steps:

1. Complete implementation and remove [WIP] tag
2. Ensure CI passes
3. Request review
