fix: use integer constant for clip_children (Godot 4.2.2 compatibility)

[itsmiso-ai]

Root cause: Control.ClipChildren doesn't exist as a GDScript enum in Godot 4.2.2. The enum is on the parent class CanvasItem and named ClipChildrenMode. Using the literal integer 2 instead works across all versions.

One-liner fix on line 259 of scripts/main.gd.

Recommendation: Approve

This is a well-scoped bug fix that addresses a runtime compatibility issue with Godot 4.2.2. The change is surgical (1 file, 1 line) and the PR body clearly documents the root cause.

Change-by-Change Findings

Location	Change	Assessment
scripts/main.gd:259	Control.ClipChildren.ALWAYS → 2	Correct. Control.ClipChildren does not expose this enum in Godot 4.2.2; the equivalent enum lives on parent class CanvasItem as ClipChildrenMode. Using the literal integer is a pragmatic cross-version workaround.

Sources

• PR body: Explicitly identifies root cause: enum moved from Control to CanvasItem, renamed to ClipChildrenMode, and GDScript binding incompatibility in 4.2.2.
• Repository workflows: Confirms Godot 4.2.2 is the active target version (.github/workflows/release.yml, .github/workflows/test.yml).
• No other usages: clip_children appears only once in the codebase (now = 2).

Standards Compliance

No violations detected against AGENTS.md conventions:

• UX Constraints: No change to visual or behavioral output. Tile panel clipping behavior remains identical.
• Implementation Notes: N/A (no save/migration logic affected).
• Change Size: Appropriately minimal. No scope creep.

Unknowns / Needs Verification

1. Magic number readability: Using 2 instead of a named constant loses semantic meaning. The author asserts this works "across all versions," but a future cleanup could explore CanvasItem.CLIP_CHILDREN_MODE_ALWAYS if that enum is consistently available. No action required on this PR.

2. Godot API documentation: While the root cause explanation is plausible (enum location/renaming), I cannot independently verify the exact Godot 4.2.2 API behavior without external docs. The fix is consistent with the stated rationale.

3. No test coverage: This specific line is not exercised by the existing test runner. However, smoke tests in CI would catch runtime failures if the value were invalid.

Conclusion

The fix is correct, minimal, and well-documented. Approve for merge.
