Claude 13250e6752 ci(performance): give the initial-bytes ratchet slack and a labelled override ...

The exact renderer.initialBytes counter failed PRs for reasons outside
their diff: two concurrent merges left master 108 bytes over the baseline
for hours, and bundler identifier renaming moves the counter by hundreds of
bytes. PRs growing it by 243 and 302 bytes had no way to pass at all,
because the direction check refuses any raised baseline.

- Counter entries accept `slack` (integer, entry unit): the ratchet enforces
  `value + slack`, reports how much slack a measurement uses, and still
  prints the tighten hint below `value`. renderer.initialBytes gets 4096
  bytes, so growth can accumulate at most 4 KiB past the last lowered
  baseline while regressions such as +35 KB still fail.
- check-baseline-direction.mjs compares `value + slack`, treats widened
  slack like a widened tolerance, and takes `--allow-increase`, which
  reports weakened entries as ALLOWED instead of failing.
- CI passes `--allow-increase` only when the pull request (or, for a master
  push, the pull request merged as the pushed commit) carries the
  perf-baseline-increase label, read from the API so a job re-run picks up
  a label added later.

This change widens the slack itself, so its own PR needs the label.
