style(pi-shell): apply rustfmt and clippy-equivalent cleanup

[Yeachan-Heo]

Summary

• preserve the requested rustfmt process-tree formatting in crates/pi-shell/src/process.rs
• apply the single semantic-preserving clippy::question_mark cleanup required by the repository Rust check at the existing task-name conversion
• keep the change as one commit on the live dev tip and do not absorb unrelated clippy cleanup

Evidence

• Base: live dev at a9189f6cad3da50cbcc66ac47ebfae4b6da8d112
• Head: updated by the force-with-lease push after rebase
• Original formatting commit preserved: 05456b20917d9a08ef6506212b6a7ad9438a4f6d
• Changed paths: crates/pi-shell/src/process.rs only
• Scope: formatting plus one lint-equivalent maintenance change; no unrelated clippy cleanup
• Semantic proof: let Some(tid_str) = name.to_str() else { return None; }; was replaced by let tid_str = name.to_str()?;, preserving the same None behavior
• Formatting: cargo fmt --all -- --check passed
• Repository Rust check: bun run check:rs passed, including cargo fmt and workspace clippy with -D warnings
• Tests: cargo test -p pi-shell passed, 202 passed, 0 failed; doc-tests 0 passed

Closes #3682

MERGE_READY — exact-head hostile review

Head under review: ec373d1dcb20a78822f523b6c92eec9fe780e192
Base: cc5873573 (current dev, post-#3686 4c6e817 + #3687 eef2afb + main-into-dev release merge)

Verdict

CI is terminal green at the exact head: 0 failed, 0 pending, all required checks pass or skip legitimately. mergeable: MERGEABLE, mergeStateStatus: CLEAN.

Hostile-review findings (all cleared)

1. Exact recovery fidelity. crates/pi-shell/src/process.rs is byte-identical to the approved exact head 091fbbff (empty diff). The original 14-green/1-red shape is preserved; nothing unrelated was absorbed.
2. Original red root cause. The Telegram guard red was a native-authority digest mismatch (8647fbf7… manifest vs regenerated tree digest). Fixed by regenerating scripts/telegram-daemon-generation-manifest.json; the process.rs entry is now 45b22243… and --validate-current-tree passes locally.
3. Guard-mandated generation bumps. The guard treats the process.rs authority change as a protected lifecycle change for both Telegram and discord. Per policy the commit ships DAEMON_GENERATION 38 → 39 and CHAT_DAEMON_GENERATIONS.discord 20 → 21, with only those two digests plus the process.rs authority digest changed in the manifest — verified line-by-line against base. No other generation was incremented; no unrelated authority was touched.
4. Scope audit. Full diff vs base is exactly five files: process.rs (formatting/clippy-equivalent only, semantics unchanged), the two generation constants with history comments, the one pinned test expectation (DAEMON_GENERATION 38 → 39 in notifications-telegram-daemon.test.ts), and the manifest. No drive-by edits.
5. Local verification at this head. cargo fmt --all -- --check clean; bun run check:rs exit 0; cargo test -p pi-shell 202/202; guard suite 42/42; --validate-current-tree VALID; notifications-telegram-daemon + daemon-control 672/672.
6. Lease discipline. Every force-push used --force-with-lease pinned to the previously observed remote head; no user work was overwritten. Rebases raced dev twice (eef2afb → cc5873573) and were re-verified each time.

Residual risk: none identified beyond the inherent daemon-generation rollover, which is the guard's intended mechanism and is covered by the lifecycle test suites above.

gajae receipt — PR #3685 exact recovery (issue #3682)

• PR: style(pi-shell): apply rustfmt and clippy-equivalent cleanup #3685 (repair/3682-pi-shell-format)
• Exact original head: 091fbbf (14 green, 1 red: telegram guard native-authority digest mismatch)
• Final head: ec373d1
• Base at push: cc58735 (live dev, post-fix(tui): preserve restart admission after repaint failure #3686 4c6e817, fix(ask): scroll ordinary question premises #3687 eef2afb, and main-into-dev release merge)

Recovery actions

1. Rebased the single commit onto live dev (twice; dev raced eef2afb -> cc58735 during CI).
2. Regenerated scripts/telegram-daemon-generation-manifest.json: crates/pi-shell/src/process.rs native authority digest 8647fbf7… -> 45b22243… (matches current tree).
3. Guard-mandated generation bumps for the protected process.rs authority change:
   • DAEMON_GENERATION 38 -> 39 (telegram-daemon-contract.ts)
   • CHAT_DAEMON_GENERATIONS.discord 20 -> 21 (chat-daemon-control.ts)
   • Manifest digests regenerated for both; full manifest regen touched exactly 3 entries (process.rs authority, DAEMON_GENERATION, CHAT_DAEMON_GENERATIONS.discord).
4. Updated the one pinned test expectation (DAEMON_GENERATION 38 -> 39).
5. process.rs remains byte-identical to exact head 091fbbf (verified: empty diff).

Verification at final head (local)

• bun scripts/telegram-daemon-generation-guard.ts --validate-current-tree: VALID
• bun test scripts/telegram-daemon-generation-guard.test.ts: 42 pass / 0 fail
• bun run check:rs: exit 0
• cargo test -p pi-shell: 202 pass / 0 fail
• cargo fmt --all -- --check: clean
• bun test notifications-telegram-daemon + daemon-control: 672 pass / 0 fail

CI at final head

• gh pr checks 3685: exit 0 (0 failed, 0 pending); required gates pass; MERGE_READY review comment posted with verdict + signature.
• mergeable: MERGEABLE; mergeStateStatus: CLEAN.

Push discipline

• All updates via git push --force-with-lease pinned to the previously observed remote head (091fbbf -> 2f26210 -> 9962d76 -> 76d0d7c -> 9b1fb53 -> ec373d1).

Status

• HELD: merge intentionally not executed per owner directive ("Do not merge yet"). Awaiting explicit merge approval.
