Add governed Clippy policy baseline

[EffortlessSteven]

Motivation

• Establish a single, governed Clippy baseline for the workspace (panic-free tests, no silent failures, AST/slice safety, suppression governance) and track planned Rust 1.94/1.95 flips.
• Provide machine-readable policy and debt ledgers plus semantic allowlists so exceptions are structured, reviewable, and expiring.
• Surface policy verification in the repo xtask so CI/local checks can validate inheritance, MSRV alignment, and allowlist/debt hygiene.

Description

• Ratchets workspace MSRV to 1.93 and adds workspace-level lint blocks under [workspace.lints.rust] and [workspace.lints.clippy] in the root Cargo.toml.
• Adds policy artifacts policy/clippy-lints.toml, policy/clippy-debt.toml, policy/no-panic-allowlist.toml, and policy/non-rust-allowlist.toml as the machine-readable ledger and placeholders for debt/allowlists.
• Adds documentation docs/CLIPPY_POLICY.md, updates clippy.toml (repo-local config, `msrv =

Not auto-merging in this PR review pass. This appears to be a near-duplicate codex variant of #261 — same Clippy baseline scope, similar MSRV bump (1.93), similar policy/ ledger files (1789 additions across 105 files vs. 1081 across 121). The PR body is also truncated mid-sentence in the "Description" section.

See the comment on #261 for the substantive concerns about merging an MSRV bump + workspace-wide lint baseline + known-failing-gate combination in a single PR. Recommend picking the cleaner of the two variants, splitting it into a "scaffold only" PR that lands cleanly, then doing the [lints] workspace = true flip in follow-ups once existing debt is addressed.
