Release v3.14.0-beta.9

Fixed

• XB6/XB7: upstream OFDMA channels now correctly classified as ofdma.
  Firmware reports Channel Type: TDMA for OFDMA upstream channels because
  docsIfUpChannelType (DOCS-IF-MIB, RFC 4546) has no OFDMA value. The
  channel type is now derived from the Modulation field instead, matching
  the DOCSIS 3.1 spec. symbol_rate and the redundant modulation label are
  correctly stripped from OFDMA channels. Addresses #107.
• XB7: malformed <th> HTML normalized before parsing. Firmware emits
  <th>Label</td><td>value</td> — unclosed <th> tags that cause
  BeautifulSoup to nest sibling cells instead of treating them as a row.
  normalize_html() now rewrites the tag at the input boundary so the table
  parser sees well-formed HTML. Addresses #107.
• inject_credential_cookie auth: body is the credential cookie value.
  Firmware that uses this pattern returns a server-issued session token in
  the auth response body; browser JS sets it directly as the credential
  cookie (createCookie("credential", result)). Core now replicates this
  correctly. An empty auth response body is treated as an error — there is
  no btoa fallback. Related to #170.

Added

• inject_credential_cookie field for url_token auth. When set,
  Core sets cookie_name to the server-issued token from the auth response
  body after login. Use for firmware where the server never issues the
  credential cookie via Set-Cookie and the browser JS reads the token from
  the response body instead.
• SB8200 modem-basic golden file regression test. modem-basic.har
  now carries a synthetic auth response body so test_modem_har_replay
  exercises the full auth → fetch → parse pipeline for this variant.
