fix(chat): preserve literal code around source chips

[waleedlatif1]

Summary

• Preserve multi-backtick code spans and fenced examples containing source or workspace-resource chips.
• Keep unmatched delimiter runs as prose, pair only within paragraphs, and recognize longer closing fences.
• Bound malformed JSON scanning by rejecting escapes outside JSON strings.
• Rebased onto fix(chat): preserve queued edits and render quoted source chips #7452; retains its citation and queued-edit fixes without duplicating them.

Type of Change

• Bug fix

Testing

• 245 message-content tests passed, including delimiter, JSON-marker, and malformed-input scaling regressions.
• Reproduced the three-backtick rendering bug and malformed escaped-JSON slowdown on current staging.
• Workspace type-checks, lint, all 45 repository audits, generated-artifact checks, and cleanup/simplification review passed.

Checklist

• Code follows project style guidelines
• Self-reviewed my changes
• Tests added/updated and passing
• No new warnings introduced

Greptile Summary

The PR fixes chat-content sanitization so literal code around source and workspace-resource chips is preserved while valid citations continue rendering.

• Treats consecutive backticks as delimiter runs and preserves fenced or matched multi-backtick code.
• Scopes delimiter pairing to prose paragraphs without splitting complete multiline chip JSON.
• Tightens JSON escape recognition to bound malformed-input scanning.
• Adds delimiter, paragraph-boundary, malformed-input scaling, and JSON-marker regressions.

Confidence Score: 5/5

The PR appears safe to merge.

No blocking failure remains; the current implementation and regressions address the previously reported delimiter-pairing and quoted-tag issues.

Important Files Changed

Filename	Overview
apps/sim/app/workspace/[workspaceId]/home/components/message-content/components/chat-content/chat-sanitize.ts	Implements paragraph-scoped delimiter pairing, fenced-code preservation, and bounded JSON-chip recognition; the previously reported failures are addressed.
apps/sim/app/workspace/[workspaceId]/home/components/message-content/components/chat-content/chat-content.test.ts	Adds focused regressions for all three prior review threads plus malformed-input scaling cases.
apps/sim/app/workspace/[workspaceId]/home/components/message-content/components/scaling-test-helpers.ts	Generalizes the scaling helper with injectable input builders while retaining its existing default behavior.
