Add X content pipeline: output gates + tweet queue + pluggable approval

Output gate (output_gate.py): Deterministic classifier that blocks system/pipeline
messages from reaching public outputs. Pattern-based detection of PR numbers,
deploy logs, diagnostics, infrastructure references.

Tweet queue (x_publisher.py): Submit drafts through output gate + OPSEC filter,
enter approval_queue, auto-post to X via Twitter API v2 on Cory's approval.

Pluggable approval stages (approval_stages.py): Extensible architecture where
adding a new approval stage = implementing ApprovalStage.check(). Current stages:
OutputGate (stage 0), OPSEC (stage 1), Human (stage 10). Designed for future
agent voting, multi-human approval, and decision markets.

Also syncs approvals.py from VPS to local repo (was deployed but never committed).

18 tests pass.
