release v0.3.0

[KaluJo]

Summary

Cuts the v0.3.0 release rolling up the in-flight watcher /
dedup / packaging work from PRs #85, #86, #87, #88 (all merged to
main).

The 0.x minor bump (rather than 0.2.10 patch) is motivated by
the breaking signature change to pcr_core::config::pcr_dir() from
#86 — returns Result<PathBuf> instead of PathBuf. The user-facing
CLI surface (pcr <cmd> flags, exit codes, output format) is
unchanged.

Release notes preview (CHANGELOG.md)

Added

• Update-available notice on every interactive pcr run (feat: "newer version available" notice on pcr runs + start CHANGELOG.md #87)
• NOTICE file with Apache 2.0 §4(d) attribution (fix(license): restore canonical Apache 2.0 LICENSE + add NOTICE #88)
• CHANGELOG.md itself — first curated changelog for this repo (feat: "newer version available" notice on pcr runs + start CHANGELOG.md #87)

Changed

• pcr_dir() returns Result<PathBuf> instead of PathBuf (watcher correctness + perf: graceful shutdown, mtime-cached scans, single-row UPDATEs, pcr_dir fail-loud #86) — breaking for pcr-core consumers
• Cursor watcher periodic scan interval 20 s → 60 s (watcher correctness + perf: graceful shutdown, mtime-cached scans, single-row UPDATEs, pcr_dir fail-loud #86)

Fixed

• VS Code Copilot Chat dual-watch dedup + captured_at hash normalisation (vscode: stop dual-watch dupes from chatSessions + transcripts #85)
• pcr start graceful Ctrl-C shutdown (watcher correctness + perf: graceful shutdown, mtime-cached scans, single-row UPDATEs, pcr_dir fail-loud #86)
• update_draft_response no longer overwrites multiple rows (watcher correctness + perf: graceful shutdown, mtime-cached scans, single-row UPDATEs, pcr_dir fail-loud #86)
• gc::orphaned batched git cat-file --batch-check (watcher correctness + perf: graceful shutdown, mtime-cached scans, single-row UPDATEs, pcr_dir fail-loud #86)
• pcr_dir() no longer silently writes auth + SQLite to /tmp (watcher correctness + perf: graceful shutdown, mtime-cached scans, single-row UPDATEs, pcr_dir fail-loud #86)
• Claude Code state cursor advances only after successful parse (watcher correctness + perf: graceful shutdown, mtime-cached scans, single-row UPDATEs, pcr_dir fail-loud #86)
• Byte-slicing on user-supplied IDs replaced with chars().take(N) (watcher correctness + perf: graceful shutdown, mtime-cached scans, single-row UPDATEs, pcr_dir fail-loud #86)
• Cursor watcher walk skipped when no mtime / notify-pending signal (watcher correctness + perf: graceful shutdown, mtime-cached scans, single-row UPDATEs, pcr_dir fail-loud #86)
• LICENSE no longer detects as "Other" — canonical Apache 2.0 (fix(license): restore canonical Apache 2.0 LICENSE + add NOTICE #88)

Verification

• cargo fmt --all --check clean
• cargo clippy --workspace --all-targets -- -D warnings clean
• cargo test --workspace — 153 passed, 0 failed (was 128 on the v0.2.9 baseline; +25 net across the merged PRs)
• cargo build -p pcr-cli --release → ✓
• ./target/release/pcr --version → pcr 0.3.0 (rust)
