Reduce lexical search result limit and field weights

[Mbeaulne]

Description

Reduces the default number of displayed search results from 50 to 10, applying the LEXICAL_RESULT_LIMIT cap to both lexical and reranked match lists so users see a focused set of results before opting into AI judgment.

Additionally, lowers the scoring weights for implementation and metadata fields significantly — implementation base weight drops from 1 to 0.25 and its phrase bonus from 2 to 0.5 — so that incidental keyword matches in command comments or container args no longer surface above results where the word appears in a component's name, description, or inputs/outputs.

Test Instructions

1. Open the component search panel and type a broad term (e.g. train). Confirm no more than 10 results are shown before triggering AI search.
2. Search for a term that appears only inside a container command comment. Confirm that any component whose name or description contains the same term ranks above the implementation-only match.
3. Run the test suite and confirm the new tests in componentSearchV2Logic.test.ts and componentSearchIndex.test.ts pass.

Additional Comments

The LEXICAL_RESULT_LIMIT constant is now exported from componentSearchV2Logic.ts so it can be referenced directly in tests to keep the cap assertion resilient to future value changes.
