feat: add B10 math and fused ops

[hashiqiqixian]

Summary

• add tile.axpy with destination reuse and exact pto.taxpy emission
• add fused tile.add_relu with exact pto.taddrelu emission
• add tile.pow / tile.pows with integer no-scratch and floating scratch/precision contracts
• add Python IR/DSL exports, focused UT/ST coverage, and paired English/Chinese docs
• keep B10 independent from B02-B09 so it can merge without relying on earlier batch PRs

Validation

• remote serial C++ build passed on /data/chenshenai/test2
• Ruff check and format check passed
• 6 focused IR/codegen unit tests passed
• A2/A3 task-submit hardware: taxpy, tpow, tpows all passed (3/3, one precompile worker)
• 964 header checks, 1080 English checks, and 81 docs parity checks passed
• validated against official PTOAS v0.53 installed under the task environment

PTOAS limitation

pto.taddrelu is emitted exactly and covered with a skip_ptoas=True codegen assertion. Official PTOAS v0.53 parses the op but its A2/A3 conversion marks it explicitly illegal, including for a full tile, so same-name hardware execution remains blocked upstream and is recorded as such in the status matrix.

Warning

Review limit reached

@hashiqiqixian, you've reached your PR review limit, so we couldn't start this review.

Next review available in: 59 minutes

Enable usage-based reviews in Billing to review now. Otherwise, wait until the next included review is available.
You're only billed for reviews past your plan's rate limits ($0.25/file).

How can I continue?

After more reviews become available, a review can be triggered using the @coderabbitai review command as a PR comment. Alternatively, push new commits to this PR.

To avoid repeated limits, reduce automatic review volume by pausing incremental auto-reviews earlier, using label-based review opt-in, excluding WIP or generated PR titles, or requesting reviews manually when the PR is ready. If your team needs uninterrupted high-volume reviews, an organization admin can enable usage-based reviews.

How do review limits work?

CodeRabbit enforces per-developer PR review limits for each organization. Most developers receive the normal plan review availability.

For paid Pro and Pro+ PR reviews, CodeRabbit uses adaptive limits for sustained high-volume activity. When a developer's recent PR review activity reaches the 95th percentile or higher among CodeRabbit users, additional reviews become available more gradually as earlier reviews age out of the rolling window.

Please refer docs for additional details.
