build(release): bump version to 0.6.0

[matheuswhite]

Bumps the crate version 0.5.1 → 0.6.0 in Cargo.toml and Cargo.lock. No code changes.

This prepares the v0.6.0 milestone, which is fully closed (14/14 issues). What lands with this release, relative to v0.5.1:

Features

• Auto complete at CLI #231 — native shell completions (scope completions <SHELL> for bash/zsh/fish/powershell/elvish)
• Windows installer #229 / Windows icon mode #230 — cargo-dist releases with a Windows .msi installer, Start-Menu shortcuts and per-command icons, plus icon mode: an interactive picker when serial/rtt is launched without its positional args
• Custom shortcuts file #211 — configurable keyboard shortcuts via an optional [shortcuts] table in config.toml
• Bookmarks #208 — bookmark lines (right-click to toggle) and navigate them with Tab / Shift+Tab
• Regex on search mode #209 — regex mode in search
• Navigation through command tags #177 — navigate the @tag autocomplete with the arrow keys
• Add a command to install a plugin #36 / Add a command to uninstall a plugin #37 — !plugin install / !plugin uninstall, so plugins auto-load across sessions

Fixes

• TUI is blinking #233 — the periodic full repaint no longer blinks the TUI (it promotes a sentinel back buffer instead of emitting ESC[2J)

Hardening & docs

• the release pipeline is guarded against non-maintainer releases (tag ruleset, owner-guarded crates.io publish, CODEOWNERS, tests/release_security.rs)
• every CLI flag and positional is now described in --help

Already shipped in v0.5.1 but part of the same milestone: #135 (headless mode), #207 (message filter), #217 (Claude Code skill).

Merging this does not publish anything

Since #229 the release is driven by cargo-dist on a vX.Y.Z tag, not by a push to main. So merging this PR is safe; the release only happens when the maintainer pushes the v0.6.0 tag afterwards, which then:

• builds the Linux/Windows/macOS tarballs, the shell/powershell installers and the Windows .msi, and creates the GitHub Release (release.yml),
• publishes scope-monitor 0.6.0 to crates.io (publish-crates.yml, reviewer-gated crates environment — irreversible, a version can only be yanked, not replaced).

Note on the version-guard check

This PR carries the release label, the maintainer escape hatch that allows the Cargo.toml version bump. Without it, version-guard fails any PR that changes the version field.
