Ticket config role profile mapping is complete and merged.

Implementation:

• 767870a ticket: add workspace ticket config
• 8fab67b ticket: reject nix profile selectors
• merge commit: 9910df4 merge: add ticket config roles

Summary:

• Added .yoi/ticket.config.toml support through crates/ticket/src/config.rs.
• Added fixed Ticket roles only:
  • intake
  • orchestrator
  • coder
  • reviewer
  • investigator
• Added role config fields:
  • profile
  • optional launch_prompt
  • optional workflow
• Did not add role-level system_instruction; durable role/system behavior remains owned by the selected Profile.
• Added backend config for local Ticket storage:
  • kind = "local"
  • root = "work-items"
• Missing config defaults to local <workspace>/work-items, all role profiles inherit, no launch prompts, and documented workflow defaults.
• Unknown roles/fields, unsupported backend kinds, malformed refs, path-like profile refs, .lua, and .nix profile refs are rejected.
• Wired the configured backend root into crates/pod/src/feature/builtin/ticket.rs.
• Preserved fail-closed/no-register behavior for malformed config or unusable backend roots.
• Kept dependency direction clean: pod -> ticket; ticket does not depend on pod or manifest.

Review:

• External sibling review initially requested one blocker fix: reject *.nix profile selectors to align with SpawnPod.profile validation.
• Coder fixed it in 8fab67b and added a focused legacy.nix rejection test.
• Re-review approved with no blockers.

Non-blocker follow-ups:

• Normalize HostAuthority::TicketBackend { root } and canonical backend root consistently before relying on root strings for stricter security/audit comparison.
• Add an execution-level Pod adapter test that runs a Ticket tool against the configured backend root.
• Later role launcher should resolve Profile selectors/prompt refs/workflow refs at runtime and commit launch prompts as user/task messages.

Post-merge validation passed:

• cargo test -p ticket
• cargo test -p pod ticket --lib
• cargo test -p pod feature --lib
• cargo check --workspace --all-targets
• cargo fmt --check
• git diff --check
• ./tickets.sh doctor
• nix build .#yoi --no-link
