fix(chat): keep mention searches open and align resource menus

[waleedlatif1]

Summary

• Keep mention searches open across spaces and punctuation, and preserve explicit dismissal while typing.
• Include organization workspaces in both mention and resource-menu search, without prematurely attaching integration-name prefixes.
• Use a stable, responsive 360px width through nested resource folders, with bounded workspace labels.
• Preserve the highlighted resource as inventories load and reopen search when replacing a dismissed trigger.

Type of Change

• Bug fix

Testing

• 40 tests passed across the prompt editor, organization composer, organization resource inventory, and resource folder tree.
• Regression tests reproduced space dismissal, Escape reopening, unintended integration attachments, and selection/programmatic replacement failures before their fixes.
• Passed app type-check, repository lint, all 52 audits, block-registry validation, and docs-manifest check.
• Browser fixture verified both composer scopes, workspace selection, multiword and punctuated searches, Escape, Enter/Tab selection, and a 375px viewport. Before/after screenshots captured with sample data. Also verified deferred loading preserves the highlighted attachment, nested folder widths, selection without reopening, and searching beyond the workspace preview limit.

• Self-reviewed my changes
• Tests added/updated and passing (new tests pass the test-audit authoring gate)

[Medium risk] Adjusts mention search behavior and dropdown menu styling.

The PR appears safe to merge; the previous findings are resolved and no new actionable issue was established.

Summary

This PR keeps mention searches usable across spaces and punctuation, adds organization workspaces to resource search, and aligns submenu widths.

• Subsequent changes preserve dismissal during selection and limit only the unfiltered workspace preview.
• All three previous findings are resolved; no new actionable issue was established.

Addressed the outside-diff dismissal finding: selecting a range that includes the dismissed @ now releases that dismissal, so replacing it at the same offset opens a fresh search. The regression failed before the change in both composer scopes and now passes; the browser flow also passes. Leaving a query with the caret intentionally resets dismissal, so returning to that query after editing elsewhere can open suggestions again. Continuing to type in the dismissed query keeps it closed.
