docs(tui): add Ratatui dashboard collaborator hand-off

[timerloggedout-spec]

Implements: TUI-RATATUI-008

Follow-up documentation for the already-promoted Ratatui/Tokio dashboard.

Changes

• add integrations/ratatui-tokio-dashboard/COLLABORATING.md
• refresh the dashboard README with the current VmRSS portability behavior
• register the collaborator hand-off as proposal item TUI-RATATUI-008
• reconcile the Ratatui proposal history with PRs feat(tui): Ratatui + Tokio responsive terminal dashboard #935, fix(tui): close Ratatui dashboard implementation gaps #938, and fix(tui): make stream batching order independent #940
• document Codespaces as the interactive fallback and GitHub Actions as the repeatable Rust validation lane
• document model invariants for stream batching, dirty rendering, quit propagation, and graceful /proc fallback

Validation

The Rust implementation itself is unchanged. Documentation/proposal files were updated only; the existing merged implementation remains the validation baseline.

This PR is intentionally based on master because the dashboard implementation is already promoted there while master-staging does not contain that implementation.

Instructions

1. Address open review disposition / threads (CodeRabbit, Devin, Copilot). Ignore pure analysis-chain dumps.
2. Prefer minimal diffs; preserve Sentinel 0o600/0o700 if those files are touched.
3. Push commits to branch docs/ratatui-dashboard-collaborator. Do not retarget away from the PR base without cause.
4. If conflicts with base exist, resolve them.
5. CodeRabbit native AutoFix, fix-CI, and conflict actions are not inferred from this feedback. They require the separate trusted command-library dispatch, live SHA, and explicit branch-write confirmation.
6. Skip pure nits by default. Always address issues affecting security or required gates with minimal, independently validated fixes.
7. Non-empty diff required — empty commits are rejected.

Interpretation: commit count is context, not quality. Empty commits are explicitly measured, not silently treated as productive work. Gross churn describes work performed across history; the final base→head diff describes what remains. Review/comment/check evidence must be evaluated separately and tied to this measured head SHA.

Validation/hand-off note:

• PR head: 543dd4f99c9bd7ad253741bc8da3ecf9b0e4d14b
• Diff is documentation/proposal-only: 5 files, no Rust implementation changes.
• COLLABORATING.md now records architecture invariants, extension points, Termux/Codespaces/Actions paths, portability, security, and troubleshooting.
• README now reflects the implemented VmRSS parsing behavior instead of the obsolete fixed-page-size note.
• Proposal item TUI-RATATUI-008 and registry history are linked to docs(tui): add Ratatui dashboard collaborator hand-off #955.
• No review threads are present.
• Current GitHub PR state reports mergeable=true.

The scoped Rust implementation was already validated in the merged #940 cohort; this PR only makes that knowledge durable for collaborators.

Steward note (Grok / evidence-led)

Live master tip at comment time: 0e1fee04fc36de009a1c89bd4148794d38963dd2 (foresight briefing evidence landed).

Promotion rule unchanged: current-SHA dual-gate (repo-gate + termux-smoke) + non-CHANGES_REQUESTED.

Dispatched this session on master:

• repo-gate.yml
• termux-smoke.yml
• github-telemetry-snapshot.yml

#955 is docs-only follow-up for already-promoted Ratatui/Tokio dashboard. Do not squash until dual-gate on the PR head (or on master after rebase) is green.

Instant-fail path-unfiltered cluster (fix-on-failure, ci-sweep, agent-jules-on-issues, actions-run-watcher, swe-reference-evaluation, context-relationship-backfill) remains #772 noise: 0 jobs, parse-time failure, not dual-gate authority.

#903 HOLD. Do not pulse #175. #184 names-only.

Dual-gate PASS on live master tip

SHA 0e1fee04fc36de009a1c89bd4148794d38963dd2:

• repo-gate dispatch 36795357857 SUCCESS
• termux-smoke dispatch 36795359091 SUCCESS

This is current-SHA dual-gate evidence for master after the foresight briefing land. #955 itself still needs its PR-head checks (repo-gate already SUCCESS on earlier head ebc02845; newer head 543dd4f9 was queued). Steward will not squash until PR-head dual-gate + non-CHANGES_REQUESTED.

Telemetry dispatch 36795366127 in progress on the same tip.
