xtaci fd709b14a3 docs: fix typos and improve comments across secondary files 
- pkg.go: fix grammar in package doc (intents→intends, aims→aim,
  golang→Go)
- snmp.go: fix typos (iput→input); clarify FECShardSet and
  FECShardMin field descriptions
- kcp_trace_off.go: fix typo (ingore→no-op)
- readloop_linux.go: improve readLoop doc comment; document batchSize
  constant
- tx_linux.go: improve tx() doc comment
- entropy.go: document reseedInterval constant

No code logic changes. Comments and documentation only.

xtaci 8fd6d90d50 perf(test): reduce 1GB echo allocations and random overhead 
- Reuse buffers and use rng.Read to cut per-iteration allocations in random echo test
- Separate RNG for payload length to keep data stream deterministic
- Optimize UDP source validation by comparing UDPAddr directly to avoid per-packet String allocation

xtaci 508806662a fix: initialize source address in readLoop from remote addr 
Previously, the `readLoop` would lazily initialize the source address (`src`) based on the first incoming packet. This behavior meant that for a short window during initialization, the session might accept a packet from an arbitrary address, potentially allowing connection hijacking or address spoofing.

This change ensures that if `s.remote` is already known (e.g., in `Dial` mode), `src` is initialized immediately before entering the loop. This locks the session to the expected remote address from thefix: initialize source address in readLoop from remote addr
