feat: prevent large payload bytes print when compression is ineffective

[yiweichi]

Purpose or design rationale of this PR

This PR improves the log, removing large payload bytes print when compression is ineffective. The payload is not meaningful for debugging, should be enough to barely print the length of original/compressed payload bytes.

Corresponding issue: #68

Your PR title must follow conventional commits (as we are doing squash merge for each PR), so it must start with one of the following types:

• build: Changes that affect the build system or external dependencies (example scopes: yarn, eslint, typescript)
• ci: Changes to our CI configuration files and scripts (example scopes: vercel, github, cypress)
• docs: Documentation-only changes
• feat: A new feature
• fix: A bug fix
• perf: A code change that improves performance
• refactor: A code change that doesn't fix a bug, or add a feature, or improves performance
• style: Changes that do not affect the meaning of the code (white-space, formatting, missing semi-colons, etc)
• test: Adding missing tests or correcting existing tests

Walkthrough

This PR modifies warning logs in the checkCompressedDataCompatibility function across codec versions v7, v8, and v9. The changes replace hex-encoded payload dumps with payload length metrics (payloadLen and compressedPayloadLen) in two warning log statements per file. No functional logic or return values are affected.

Changes

Cohort / File(s)	Summary
Logging updates in codec versions encoding/codecv7.go, encoding/codecv8.go, encoding/codecv9.go	Modified warning logs in checkCompressedDataCompatibility to report payload lengths instead of hex-encoded payload dumps. Two log statements per file updated: one on compression compatibility failure, one on length check failure. Purely diagnostic changes with no behavioral impact.

Estimated code review effort

🎯 1 (Trivial) | ⏱️ ~5 minutes

• Homogeneous changes applied consistently across three identical files
• Non-functional logging-only modifications
• Straightforward field substitution with no logic changes

Possibly related issues

• Excessive logging of full payload bytes in compression warning bloats log files #68: This PR directly addresses the objective of removing hex-encoded payloads from logs and replacing them with length metrics to reduce log verbosity.

Possibly related PRs

• fix: check v7 batch compressed data compatibility #52: Related modification to checkCompressedDataCompatibility in the v7 codec; should verify for potential merge conflicts or interaction with signature/control flow changes.

Poem

🐰 Logs were thick with hex-encoded dreams,
But now they flow with length-based streams,
Smaller files, cleaner sight,
A rabbit's trim delight! ✨

✅ Passed checks (3 passed)

Check name	Status	Explanation
Title check	✅ Passed	The PR title clearly and specifically describes the main change: preventing large payload bytes from being printed in logs when compression is ineffective, which aligns with the changeset modifications across three codec files.
Docstring Coverage	✅ Passed	No functions found in the changed files to evaluate docstring coverage. Skipping docstring coverage check.
Description check	✅ Passed	The PR description covers the purpose/rationale and includes linked issue, but the PR title itself is not provided separately—only the conventional commits template is shown.
