v0.8.0 — Editable roster in the knob panel

Completes the deferred half of the C5 knob GUI: the tanglebrain-gui roster card is now editable, comment-preserving, with zero new runtime dependencies.

Added

• Editable roster in the knob panel (plan §5/§9.2). A focused set of per-entry scalar fields is editable from the panel — enabled, can_orchestrate, budget_usd_month, good_at — each row with its own Save.
  • Comment-preserving, no new deps: a new tanglebrain/roster_edit.py edits the targeted value on the targeted line in place, so every inline comment, blank line, the nested invoke block, and the commented paid-API example survive byte-for-byte — no YAML round-trip library. Adding/removing/reordering entries and editing the invoke block stay hand-edits.
  • Write-safety mirrors the pricing editor: edits are validated and the candidate is re-parsed with the real loader before any write (a surgical slip can never land a malformed roster), the prior file is backed up to <state_dir>/backups/roster-<ts>.yaml, and the write is atomic. The panel sends only changed fields and confirms before overwriting the tracked config/roster.yaml.
  • New views.save_roster_view() + POST /api/roster.

Notes

• 295 hermetic tests pass; independent Critic review found no blockers.
• With this, the planned build (C0→C7 plus the deferred GUI roster-editing item) is complete.
