docs: close out v0.7.0 "Resolution" release notes, bump crate versions

[doublegate]

Summary

• Restructures CHANGELOG.md's [Unreleased] into ## [0.7.0] "Resolution" - 2026-07-09, closing out the release this session's PRs docs(plan): rewrite v0.7.0-v1.0.0 ladder to front-load breadth, matching RustyNES's v1.0.0 #44/feat(ppu): implement true 512-px hi-res (Modes 5/6) output #45 landed (the breadth-inclusive ladder rewrite + true 512-px hi-res output).
• Updates to-dos/VERSION-PLAN.md's v0.7.0 heading to RELEASED and to-dos/ROADMAP.md's Release line.
• Merging this to main should trigger release-auto.yml to automatically tag and publish v0.7.0 (an empty [Unreleased] immediately followed by a real ## [X.Y.Z] heading is its trigger signal).
• Bumps every workspace crate's Cargo.toml version (and the internal path-dependency version constraints referencing them) from the placeholder 0.1.0 to 0.7.0, matching the actual project version. Requested explicitly — these were previously left pinned since nothing here publishes to crates.io and release-auto.yml keys off CHANGELOG.md structure, not Cargo.toml.

Test plan

• cargo check --workspace green, all crates now report v0.7.0
• cargo clippy --workspace --all-targets -- -D warnings clean
• cargo fmt --check clean
• Markdown integrity check on every touched doc

Pull request overview

Closes out the v0.7.0 "Resolution" release by restructuring release notes and planning docs to mark the rung as released, and aligns the Rust workspace crate versions (and internal path-dependency version constraints) to 0.7.0 so the repo’s package metadata matches the project’s tagged release versioning.

Changes:

• Restructured CHANGELOG.md to introduce ## [0.7.0] "Resolution" - 2026-07-09 immediately after an empty [Unreleased] section (the release-auto.yml trigger pattern).
• Updated planning docs (to-dos/VERSION-PLAN.md, to-dos/ROADMAP.md) to reflect v0.7.0 as released.
• Bumped workspace + all workspace crates from 0.1.0 to 0.7.0, updating internal dependency version constraints and Cargo.lock accordingly.

to-dos/VERSION-PLAN.md:333

• This section now marks v0.7.0 as released, but earlier in this document (and in .github/workflows/release-auto.yml’s header comments) it still says crate Cargo.toml versions “stay pinned at 0.1.0”. With this PR bumping crate versions to 0.7.0, those explanations become incorrect and could confuse future release automation edits (even if the trigger remains CHANGELOG structure).

### v0.7.0 "Resolution" — true hi-res output — **RELEASED 2026-07-09**

The one item from `v0.5.0`'s carried-forward PPU gap list that's genuinely bounded, with no
external unknowns (no ROM sourcing, no open-ended root-causing): full 512-px hi-res (Modes 5/6)
output. Kept as its own minor rather than folded into the accuracy-debt cluster below, matching
this project's one-theme-per-`v0.x.0` convention every prior rung has held to.
