docs: add X/Twitter competitor signal guidance

[kriptoburak]

Summary

• Merge current upstream v2.0.1 and resolve the former conflict without dropping upstream changes.
• Add optional, read-only public X evidence to competitor research guidance.
• Distinguish the TweetClaw OpenClaw plugin from Xquik's remote MCP endpoint.
• Register the integration as reciprocal source and claim records under CLM-0210.
• Keep organic evidence separate from paid spend, targeting, performance, and attribution.

Independent repository fixes

• Align the Python package, core CLI, and report generator with public version 2.0.1 metadata.
• Bind the updated project metadata to the reviewed dependency inventory checksum.
• Add a regression test covering every public and runtime version surface.
• Make the native target verifier test independent of host platform subprocess calls.

Validation

• python -m pytest tests/release tests/audit/test_source_grounding.py tests/core/test_cli.py -q - 89 passed.
• python -m pytest tests/core -q - 238 passed, 1 skipped.
• python scripts/release.py audit - passed across 339 tracked files.
• Python compile, shell syntax, JSON parsing, focused release tests, and diff checks passed.

Scope

• Read-only competitor research only.
• No ad-account write behavior or credentials added.
• No organic signal is presented as paid-platform performance data.

The v2.0.1 conflict is resolved and the repaired branch is published at f3707158a34855c688f9d1a08c0ecfc0bc0ca4b0.

The final diff preserves the current upstream release, adds source-grounded Xquik competitor evidence, and fixes independent release defects: stale 2.0.0 runtime/package version values, their reviewed inventory checksum, version-parity regression coverage, and host-dependent native verifier testing.

Validation completed:

• 89 release, source-grounding, and CLI tests passed.
• 238 core tests passed and 1 optional PDF test skipped before runtime extras were installed.
• The 339-file release audit, Python compile, shell syntax, JSON parsing, and diff checks passed.

This is ready for maintainer review.
