* fix(browser): harden existing-session driver validation, session lifecycle, and code quality
Fix config validation rejecting existing-session profiles that lack
cdpPort/cdpUrl (they use Chrome MCP auto-connect instead). Fix callTool
tearing down the MCP session on tool-level errors (element not found,
script error), which caused expensive npx re-spawns. Skip unnecessary
CDP port allocation for existing-session profiles. Remove redundant
ensureChromeMcpAvailable call in isReachable.
Extract shared ARIA role sets (INTERACTIVE_ROLES, CONTENT_ROLES,
STRUCTURAL_ROLES) into snapshot-roles.ts so both the Playwright and
Chrome MCP snapshot paths stay in sync. Add usesChromeMcp capability
flag and replace ~20 scattered driver === "existing-session" string
checks with the centralized flag.
