prepare v0.5.0 release

[snimu]

Summary

• bumps the root and published packages from 0.4.0 to 0.5.0 with synchronized internal dependency ranges
• uses a minor release because current main includes the session action scheduler rework, which bumps the daemon protocol to 7 and schema revision to 8; older clients and daemons are rejected cleanly at connect
• finalizes the 2026-08-03 changelogs: the session action lifecycle/store rework and its user-visible fixes (active work misreported as queued, headless early exit, /compact self-consumption), plus bounded large-session loading, deleted-subagent cleanup, daemon snapshot reliability, autonomous guidance, and UI polish
• updates only version fields and internal ranges in the lockfile without mixing application code into the release diff
• main skips 0.4.1: prepare v0.4.1 release #590 was prepared before the scheduler stack (refactor(coding-agent): extract session action contract helpers #572-refactor(coding-agent): harden session action races #576) merged, so its patch framing and validation no longer describe main; it will be closed unmerged
• rebased onto main at 1793cbc to include fix(coding-agent): echo salvaged command id in daemon parse failures #592 (daemon parse failures echo the salvaged command id) and fix(coding-agent): surface seeded --goal objective to the model #593 (seeded --goal objective surfaced to the model); their changelog bullets are folded into the [0.5.0] Fixed section

Release validation

• Current main candidate installed through the public beta installer in fresh Prime Sandboxes
• Beta pointer, immutable artifact, release SHA256SUMS, and direct tarball SHA-256 matched
• prime-agent --version, status, and doctor succeeded
• Fresh unauthenticated onboarding produced clear login guidance
• IPython kernel bootstrap and persistent two-cell round trip succeeded
• Authorized headless inference invoked IPython and returned the expected result
• Durable session stop/restart/resume continuity succeeded
• Old-client/new-daemon and new-client/old-daemon mixes fail cleanly at connect (protocol 7 / schema 8)
• Daemon shutdown, restart, health, and final cleanup succeeded
• Full PR CI green
• Macroscope and Cursor Bug Bot findings reviewed and resolved/dismissed
• At least one human approval

Beta validated: v0.4.0-beta.426.1.1793cbc from main at 1793cbc (includes #592 and #593); tarball SHA-256 726dc3f0fefe3740becaa77768bf075aebabec591f21cc05ab0e44191c9b7eb4. Full checklist re-run for each rebase: 3b2d1f2 (stack head), e4a5909 (+#592: old-client rejection now immediate instead of a 30s timeout), and 1793cbc (+#593: verified --goal objective is now visible to the model on the first turn and correctly reported by -c continuations).

Local validation

• version bump via the release skill flow (root + 4 published packages), node scripts/sync-versions.js clean
• lockfile updated for version fields and internal ranges only; npm ci --ignore-scripts --dry-run clean
• git diff --check clean; example/private workspace versions untouched
• npm run check green

Guardrail

This PR is intentionally version/changelog-only. Do not merge until every release-validation checkbox above is complete.

Note

Low Risk
This diff is version and changelog metadata only; runtime risk comes from already-merged 0.5.0 behavior (daemon protocol 7 / schema 8), not from merging this PR.

Overview
Prepares v0.5.0 by bumping prime-agent and the four published workspaces (pi-agent-core, pi-ai, pi-coding-agent, pi-tui) from 0.4.0 to 0.5.0, aligning internal ^0.5.0 dependency ranges in root package.json, each package manifest, and package-lock.json.

The coding-agent changelog is finalized for 2026-08-03: unreleased notes move under [0.5.0], including the breaking session action scheduler rework (daemon protocol 7, schema revision 8), plus fixes for queued vs active work, headless early exit, /compact successor handling, and daemon parse error command IDs. agent, ai, and tui changelogs gain dated 0.5.0 section headers without new bullet content in this diff.

No application source changes—only versions, lockfile version fields, and changelog text.

Note

Bump all packages from v0.4.0 to v0.5.0 for release

Increments versions across all workspace packages (pi-ai, pi-agent-core, pi-coding-agent, pi-tui, and the root package) from 0.4.0 to 0.5.0 and updates cross-package dependency ranges to ^0.5.0. The coding-agent changelog documents breaking changes including a session input scheduling rework (protocol 7/schema 8), along with several fixes and state reporting changes.
