* feat(sinafinance): rewrite stock as public API adapter
Replace browser-based DOM scraping with direct Sina public APIs:
suggest3.sinajs.cn — symbol search (GBK, no auth)
hq.sinajs.cn — real-time quote (GBK, no auth)
Strategy.PUBLIC, browser: false — no Chrome or login required.
Supports A股 (sh/sz), 港股 (hk prefix), 美股 (gb_ prefix).
US MarketCap parsed from hq field [12]; formatted as T/B/M.
* feat(exit-codes): add Unix-standard exit codes to all CliError types
Introduce EXIT_CODES constant table (sysexits.h conventions) and wire
exitCode into every CliError subclass so the process exit code reflects
the semantic type of failure:
0 success (default)
1 generic / unexpected error
2 argument / usage error (ArgumentError)
66 empty result / not found (EmptyResultError, SelectorError)
69 service unavailable (BrowserConnectError, AdapterLoadError)
77 permission / auth required (AuthRequiredError)
78 configuration error (ConfigError)
124 timeout (TimeoutError)
130 Ctrl-C / SIGINT (unchanged, tui.ts)
resolveExitCode() in commanderAdapter.ts reads err.exitCode for typed
CliErrors, and falls back to pattern-matching message text for untyped
adapter errors (auth pattern → 77, not-found pattern → 66, else → 1).
Shell scripts can now distinguish error categories:
opencli spotify status || echo "exit $?" # 69 if browser not running
opencli github issues --repo x 2>/dev/null; [ $? -eq 77 ] && opencli github auth
* review: regex escape sym, fix change precision, optimize suggest type param
