test: colocate elicitation and state tests

[zatevakhin]

Scope

Publishes the independently reviewed Phase 10 state/input ownership test slice from exact head a134bbe3a70b76d53ec5733c734542c3f323392b (tree 751bfaf3d279bda17d6cf4266f796c9da2dcc5de) on base 5f0cf2ad49390610c241dfbaf7b0007f8362c096.

The approved two-commit range is:

• c0effee0682be201239d8d83cd8ccba681add194 — test: colocate elicitation and state tests
• a134bbe3a70b76d53ec5733c734542c3f323392b — test: preserve state input edge contracts

This is test-only ownership cleanup across exactly five existing source files (+876/-1321):

• move pure elicitation input tests to src/features/chat/input/elicitation.rs
• move session projection/state-transition tests to src/session_state.rs
• move delegate projection tests to src/delegates_state.rs
• retain meaningful App composition, forwarding, filesystem, routing, and application contracts in src/app.rs
• retain runtime effect-execution and failure-handling contracts in src/runtime/mod.rs

The intentional duplicate removal reduces the all-feature inventory from 1,173 to 1,148 tests without changing production behavior.

Review

Linus independently re-reviewed the corrected aggregate range through the exact head and approved it with no findings. The slice was judged safe to publish and squash-integrate after hosted CI passes on that exact SHA.

Validation

Local validation passed before publication:

• focused elicitation, session-state, delegate-state, App, and runtime suites
• repeated all-feature debug and release runs: 1,148 passing
• all-targets test coverage
• formatting, check, Clippy, and build gates
• production-code identity check
• changed-scope, manifest/dependency, and protected-path audits

Unavailable and not claimed: live ACP backend, compatible WebSocket endpoint, subprocess, terminal, clipboard, or full interactive UI smoke testing.

Integration

Use guarded squash integration with --match-head-commit a134bbe3a70b76d53ec5733c734542c3f323392b. Retain the source branch for provenance.
