chore: prepare v0.9.1 release

[snimu]

Prepares the v0.9.1 patch release. Exactly one change on top of v0.9.0: the fix for the empty Inactive section in the agents view (#1960 / ENG-5840) — the saved-session catalog now loads progressively when the view opens instead of only when a search query is typed, restoring the inactive rows that the v0.9.0 roster seed scoping removed from the view's data path.

Version bump 0.9.0 → 0.9.1 in lockstep (root + workspaces, ranges synced per RELEASING.md's manual path), lockfile refreshed minimally from main (15-line diff, no third-party drift), and the single changelog fragment folded into the coding-agent 0.9.1 section.

Validation

• root npm run check (biome, tsgo, installer render, browser smoke) — pass on the release branch after bump + aggregation
• node scripts/sync-versions.js — lockstep confirmed
• fix(coding-agent): load the saved catalog when the agents view opens #1960's own gate: fix pin fails on v0.9.0 main and passes with the fix; 226 tests green across 10 agents-view/roster/catalog files in a sandbox; measured on a 3051-session corpus (first inactive row ~10ms after view open, complete 2.2s warm)
• full-suite sandbox gate at the release base + fresh-agents-view cross-surface check per RELEASING.md: running now, result will be posted as a PR comment before merge

Release sequencing

Prepare-only: no tag, no publish. After merge: tag v0.9.1 and npm run publish.

Linear: ENG-5839 (release tracking), ENG-5840 (the regression)

Note

Low Risk
Version and changelog-only changes with no runtime code edits in this PR.

Overview
Prepares the v0.9.1 patch release with no application code in this diff—only monorepo versioning and release notes.

Bumps 0.9.0 → 0.9.1 in lockstep across the root prime-agent package, @earendil-works/pi-* workspaces, example extension packages, and package-lock.json dependency ranges. Adds a [0.9.1] entry to packages/coding-agent/CHANGELOG.md documenting the agents view regression fix (Inactive section empty until search; saved-session catalog now loads progressively on open). Removes the folded .changes/agents-view-inactive-catalog.md fragment.

Note

Prepare v0.9.1 release across all packages

• Bumps versions from 0.9.0 to 0.9.1 in the root and packages: agent, ai, tui, and coding-agent, plus example extensions
• Updates internal @earendil-works/* dependency ranges to ^0.9.1 accordingly
• Adds a 0.9.1 section to CHANGELOG.md noting a fix for the agents view Inactive section loading on fresh view

Release gate result (run at 194ae62, completed post-merge):

Full suite (CI-mirrored, sandbox): PASS — 4 failed / ~5,547 passed, failures exactly the environmental baseline (root-EACCES tools x2, config not-writable, 4603 lsof), zero new failing files. Per-package: agent 70/70, ai 341 (API-key suites skipped), tui 750/750, coding-agent shards 4,560 passed + process 11 + kernel 15, runtime python 269 OK.

Cross-surface checks (RELEASING.md, first run): 8/8 PASS on a fixture of 307 saved sessions + 6 dead subagent families + live parent with running/completed children: list live-only, list --all (all dead-family child rows present), fresh agents view with no search (Running/Idle/Inactive all populated, Inactive filled progressively — the v0.9.0 regression surface, #1960 verified live), search narrowing, subagents bar counts, resume, wake-completed-subagent by name, and a real coordinator-driven post-update restart restore (7/7 restored, views intact after).

Non-blocking pre-existing observations (not in the 0.9.1 delta): list without a daemon prints a raw ENOENT instead of a friendly empty state; CLI send/-r don't resolve dead-family child names (wake works via agents-view drill-in); a transient "Cannot list heartbeats while session worker is starting" surfaced during restart restore (cosmetic, self-healed).
