OPE46-00034: OPE46-00034: QoL: Add process filtering improvements

[andrei-hasna]

Automated task drain for OPE46-00034.

Task: OPE46-00034: QoL: Add process filtering improvements

Agent verdict: DONE
Added process owner/name filters and parent-child tree rendering to monitor ps with owner-aware collection and offline coverage.

Independent review: APPROVE

The process owner/name filters and tree rendering are correctly wired through the live local, SSH, and EC2 collection paths, preserve the existing JSON row shape and pagination, and have meaningful unit and CLI coverage. No secrets or remaining out-of-scope changes were found.

Reviewer fix applied:

• src/collectors/process-list.ts:4 originally requested GNU ps's default-width user= field. A valid owner such as systemd-network is truncated (for example, to systemd+), so monitor ps --user systemd-network returned no rows. The command now requests user:32=.
• src/collectors/process-list.test.ts:5 adds a regression assertion that fails with the original command, and line 9 verifies preservation of the long owner value.
• Removed the unrelated duplicate typecheck package s

The reviewer made corrections, committed separately.

Opened by the e2b-task-drain fleet (codex gpt-5.6-sol, effort xhigh).
