fix: use exact match for mcporter tool capability validation

actualTools.some(a => a.includes(t)) is a substring check —
'vector_search'.includes('search') === true, so a missing 'search'
tool would be silently masked by 'vector_search' existing.

Switch to actualTools.includes(t) for strict equality per element.
