Fuzzy completion: SHOW QUERY PROFILE fingerprint completion

[apstndb]

Summary

Add fuzzy completion for SHOW QUERY PROFILE <fingerprint> to select from cached query profiles.

Background

SHOW QUERY PROFILE requires typing a fingerprint integer. The available profiles are already fetched by SHOW QUERY PROFILES.

Design

• New completion type: fuzzyCompleteQueryProfile
• Data source: cached/fetchable query profiles (same as SHOW QUERY PROFILES)
• Uses fzfItem{Value, Label} (Fuzzy finder: introduce fzfItem for display/insert text separation #525) for display/insert separation:
  • Value (inserted): fingerprint
  • Label (displayed/searched): fingerprint with query text preview
• May need network call to fetch profiles if not cached

Acceptance Criteria

• SHOW QUERY PROFILE + Ctrl+T shows list of available query profiles
• Each entry shows fingerprint and query text snippet for identification
• Selected fingerprint is inserted into the statement

Prerequisites

• Fuzzy finder: introduce fzfItem for display/insert text separation #525 (fzfItem display/insert separation)
