Aditya Patwardhan 984ea5ad81 fix(esp_http_server): reject Content-Length above UINT32_MAX 
In httpd_parse.c, cb_headers_complete() converted the HTTP parser's
content_length (uint64_t) to the request's content_len (size_t) via an
unsafe cast through (int). On a 32-bit size_t target a Content-Length
above 4 GiB silently truncated, enabling request smuggling where the
server and an upstream proxy disagree on the body length (CWE-681).

Reject any Content-Length above UINT32_MAX with 413 Content Too Large
before any handler runs. UINT32_MAX is the largest body length the
server can represent in size_t content_len on every target, so this is
the maximum the server can support; no configuration knob is needed.

Closes SEC-102
Closes SEC-229

Sarvesh Bodakhe 76c56a7b8d fix(wifi): fix NAN availability time bitmap parsing issue 
Accept spec-legal NAN availability time bitmaps (period > 512 TU,
bitmap length > 4, full 9-bit start offset) so iPhone secured NDP
setup is no longer rejected with NDL_UNACCEPTABLE.

Fixes NAN NDP interop with the iPhone 17 series.

Sarvesh Bodakhe 7aee122f30 fix(wpa_supplicant): accept NIK follow-up key descriptor with Key Type=0 
iPhone (and hostap) set Key Type=0 in the pairing NIK follow-up Shared-Key
Descriptor (key_info=0x1340) since the NIK is not a pairwise key. We required
the pairwise bit and rejected the frame before decryption, so the NIK
exchange timed out and pairing was torn down. Require only the Encrypted
Key Data bit.

Marek FialaandCursor cf09ccd766 fix(tools): send mcp-server startup diagnostics to stderr 
idf.py mcp-server printed startup, shutdown, and error messages on
stdout. On the stdio MCP transport, stdout is the JSON-RPC channel, so
those non-JSON lines can confuse or break strict clients. Route them to
stderr like the other diagnostics in mcp_ext.py.

Marek Fiala a6c3f023a2 fix(tools): detach MCP tool subprocess stdin from JSON-RPC pipe 
idf.py mcp-server tool handlers were spawning idf.py without redirecting
stdin, so the child inherited the long-lived MCP JSON-RPC transport and
could hang indefinitely on tools/call. Pass stdin=subprocess.DEVNULL on
every spawn of idf.py.
