5. p2p: cap maxconnections at 2000

   Limit the configurable automatic peer count to 2000, leaving headroom below the default orphanage latency limit.
   
   Apply the cap before reserving file descriptors. Use saturating `int` parsing so oversized arguments cannot wrap before the cap is applied.

6. test: characterize proxy network name errors

   The `-proxy` error lowercases unsupported network names, unlike `-onlynet` and `getnodeaddresses`.
   Also cover rejection of the `tor` name removed in #34031, mixed-case `onion` acceptance, I2P exclusion, and clearing the IPv4 and name proxies together.

7. refactor: share proxy network parsing

   Use the shared network parser to select each per-network proxy, matching `-onlynet` and `getnodeaddresses`.
   Keep accepted names, proxy assignments, and error messages unchanged.

8. net: preserve network name case in proxy errors

   `-proxy` lowercases unsupported network names in its error message, unlike `-onlynet` and `getnodeaddresses`.
   Let the shared parser handle case-insensitive matching so the diagnostic retains the user's spelling.

9. doc: use onion in proxy help and examples

   `tor` was removed as a network name in #34031, but the proxy help and Tor examples still advertise it.
   Use canonical network names in the help and document `onion` with the removal reference.

    The release note adaptation for #35919 seems fine.

    All commits from all PRs are present, and all PRs are noted correctly.
