v1.2.1: IP-literal fast-fail + more SNIs + x.com GraphQL fix + Android SNI paste

Rollup of the three upstream-Python ports plus an Android UX polish:

- plain_tcp_passthrough: 4s connect timeout for IP literals (10s for
  hostnames). Halves Telegram DC-rotation latency when the current DC
  is DPI-dropped.
- DEFAULT_GOOGLE_SNI_POOL / DEFAULT_SNI_POOL: +maps, chat, translate,
  play, lens.google.com. More fingerprint spread, and maps/play pass
  DPI on some carriers where shorter *.google.com names don't.
- handle_mitm_request: x.com GraphQL URL truncation — strip everything
  after the first & when the path matches /i/api/graphql/.../?variables=.
  x.com's variables+features+fieldToggles blob overflows Apps Script's
  URL cap; `variables=` alone renders the timeline.
- Android SNI editor: paste-and-add now accepts a full list separated
  by whitespace / commas / newlines, dedupes, and merges with existing
  selection. Closes the "add them all at once" ask from #47.
- rlimit.rs: fence the example error log in a `text` code block so
  rustdoc stops trying to compile it.

+• x.com loading fix: truncate long GraphQL URLs that were overflowing Apps Script's URL length cap and bouncing with a generic relay error (ported from upstream Python)
+• Android SNI editor: paste a whole list of subdomains once and Add picks them all up — whitespace, comma, and newline separated all work (issue #47)
