fix(naming): client-side unique duplicate names for blocks

[waleedlatif1]

Summary

Implements client-side unique name generation for duplicated blocks, standardizing to "<Base> N" and preventing normalized collisions within a workflow. This keeps resolver/store normalization rules in sync and avoids server-side changes.

Why

• Avoids confusing name collisions after duplicate, especially across variants that normalize equal (e.g., "My Agent" vs "myagent").
• Ensures consistent UX across both duplicate entry points (collaborative and local store) with a single source of truth.
• Honors product decision to rely on client-side uniqueness only; server behavior unchanged.

Changes

• Added helper at apps/sim/lib/naming.ts:
  • normalizeBlockName(name) – lowercase + strip spaces (parity with resolver/store).
  • generateUniqueBlockDuplicateName(existingNames, sourceName) – produces "Base N"; starts at suffix+1 when source ends with whitespace+digits, otherwise 1; loops until normalized-unique.
• hooks/use-collaborative-workflow.ts → collaborativeDuplicateBlock now uses the helper with current workflow block names.
• stores/workflows/workflow/store.ts → duplicateBlock now uses the helper.
• updateBlockName in store now imports the shared normalizeBlockName to avoid drift.
• Tests: apps/sim/lib/naming.test.ts covering base/suffix cases, normalization collisions, gaps, whitespace-heavy names, mixed case, and empty names.

Impact

• Client-only change; server endpoints and duplication behavior remain unchanged.
• Rename validation continues to prevent normalized collisions; no regressions expected.

QA

• Create blocks: "Agent", "Agent 1". Duplicate "Agent" → expect "Agent 2".
• Create "Agent 3". Duplicate "Agent 2" → expect "Agent 4".
• Create "agent1" (if allowed). Duplicate "Agent" → should skip to next free beyond normalized collisions.
• Names with multiple spaces: "My Agent" duplicates to "My Agent 1"; if a normalized collision exists, increments accordingly.

Notes

• No server behavior changed; resolver normalization remains the source of truth we mirrored.
• Keeps naming behavior consistent whether duplication originates locally or via collaboration.
