Chinesezjc 9b29d0226e fix(code-runtime-python): make the log seal incremental, scope the soft-lowering to RLIMIT_CPU, and capture memoryview
Addresses the bot's follow-up review findings on the settlement-path fixes:
- The _LogStream seal joined the WHOLE accumulated buffer past the fragment cap,
  re-copying the growing block O(B^2/cap) times for a large drip. It now seals
  only the current fragments into a _pending_blocks entry (character count
  unchanged), so a 25 M single-character drip stays O(B); the newline/flush/
  _push_bounded_prefix consumers join blocks + fragments once.
- The _clamped soft==hard lowering is scoped to RLIMIT_CPU: for RLIMIT_AS a
  one-byte soft differential would only misalign the child's applied limit with
  the host-side budget gate, with no signal to preserve. The hard == 1 blind
  spot is documented.
- send_done's fallback captures memoryview at import (_memoryview) alongside
  os.write, so a one-line rebind of the name cannot change the fallback write;
  the comment now states the module-level-captured mechanism.
